Definition Contraception (birth control) prevents pregnancy by interfering with the normal process of ovulation, fertilization, and implantation. There are different kinds of birth control that act at different points in the process. Unfortunately, there is no perfect form of birth control. Only abstinence can protect against unwanted pregnancy with 100% reliability.

Risk Misperception & Patients
“…incorrect perceptions of excess risk of contraceptive products may lead women to use them less than effectively or not at all.” ‘ ‘ Talking Points Gardner and Miller assert that the following factors may lead women to use contraceptives less than effectively or not at all: Problems with uneven access Prescription requirements Conflicting information on the package instructions for initiating and continuing use Incorrect perceptions of excess risk Reference Gardner J, Miller L.

Misperceptions Affect Health Decisions
1995 – Warning: possible increased risk of VTE among users of 3rd generation OCs Many women discontinued OC use Prescribing patterns changed Pregnancy and abortion numbers increased Deemed a “non-epidemic” Talking Points VTE = venous thromboembolism The negative consequences of an inaccurate perception of the risks associated with oral contraceptives played out in Europe to unfortunate effect. In 1995, the British Committee on Safety of Medicines issued a warning regarding a possible increased risk of venous thromboembolism among users of 3rd generation oral contraceptives (those containing newer progestins desogestrel and gestodene). Many women across Europe stopped taking their OCs or switched formulations. Providers changed prescribing patterns. There were 26,000 more pregnancies in Wales and England in 1996 than in 1995, with about 13,600 additional abortions. The abortion rate had been decreasing over the 5 years before to the event. It is now believed that preferential prescribing may have been responsible for at least part of the association between 3rd generation OCs and VTE; in any case, the risk appears to be small. Even if the reported increase in risk is true, it is clinically insignificant. Deemed a “non-epidemic” by some experts. References Chasen-Taber L, Stampfer M.

“The possibility of suffering
Definition of Risk ‘ ‘ “The possibility of suffering harm or loss.” Talking Points To effectively communicate about risk, it’s important to have a clear and accurate understanding of the basic statistics underlying risk comparisons. What is “risk”? Here’s a definition straight from The American Heritage Dictionary of the English Language. A risk is the possibility of suffering harm or loss.” Note that risk is the probability—or chance—of an event happening; it does not indicate certainty that it will occur.

Associations vs. Causality
An association does not always mean exposure caused outcome It could be due to random chance or bias Making a decision about causality requires that a number of criteria be met, including (among others): Strength of the association (as measured by relative risk, for example) Consistency of the association over multiple studies Temporal sequence (exposure precedes outcome) The point is that a weak association found in a single study should not be taken as concrete evidence of a cause-and-effect relationship. Talking Points The existence of a statistical association does not necessarily mean that the exposure caused the outcome. Reasons for an association without a true underlying causal relationship include random chance, bias, and other factors. Making a decision about causality requires that a number of criteria be met, including (among others): Strength of the association (as measured by relative risk, for example) Consistency of the association over multiple studies Temporal sequence (exposure precedes outcome) The point is that a weak association found in a single study should not be taken as concrete evidence of a cause-and-effect relationship.

Example of Absolute Risk
Of 100,000 women on 3rd generation OCs, 30 will develop venous thromboembolism (VTE) per year Absolute risk Talking Points As an example, of 100,000 women taking 3rd generation OCs, approximately 30 will develop VTE per year. Absolute risk = 30 per 100,000 woman-years. As you know a woman (or person) year the total of the units of time, whether weeks, months, or years, that people were exposed to a condition or were actively involved in a study. One person-year can represent a single person who was exposed for one year or an accumulation, such as two people who were each exposed for half a year. In this example the person-time units are woman-years. Reference Mills, A. Combined oral contraception and the risk of venous thromboembolism.

Absolute Risk Reduction
The difference in risk of the outcome between those exposed and those not exposed Risk in exposed – risk in unexposed Reflects the reduction in risk associated with an intervention Talking Points Absolute risk reduction is the difference in risk of the outcome between those exposed (to an intervention) and those not exposed. Absolute risk reduction = risk in those exposed – risk in those who were not exposed.

Example of Absolute Risk Reduction
Of 100,000 women on 2nd generation OCs, 15 will develop VTE per year Absolute risk reduction Absolute risk = 15 per 100,000 woman-years 15 per 100,000 woman-years Talking Points The absolute risk of VTE for 2nd generation OCs users is 15 per 100,000 woman-years. Therefore, the absolute risk reduction is the difference in absolute risk for women taking 3rd generation and for women taking 2nd generation OCs. Absolute risk reduction = 30 – 15 = 15 per 100,000 woman-years Therefore, women taking 2nd generation OCs have a risk that is 15 per 100,000 lower than women taking 3rd generation OCs Reference Mills A.

Attributable Risk Similar to absolute risk reduction
Attributable risk is: The difference in risk of the outcome between those exposed and those not exposed Risk in exposed – rate in unexposed Reflects degree of risk associated with exposure Talking Points Attributable risk is the difference in risk of the outcome between those exposed and those not exposed Attributable risk = risk in exposed – risk in unexposed Similar to absolute risk reduction, but indicates degree of risk associated with exposure, rather than specifically the reduction of risk associated with an exposure Reference BMJ Collections: Comparing disease rates.

Relative Risk Used to identify an association between exposure and outcome Exposure Outcome Talking Points Relative risk Is the frequency of the outcome in the exposed group divided by the frequency of the outcome in the unexposed group Reflects the likelihood of developing the outcome based on exposure Is used to identify an association between exposure and outcome Is similar to odds ratio References Grimes DA, Schulz KF.

Odds Ratio Used to identify an association between exposure and outcome in a case-control study Similar to relative risk X Exposure Outcome Talking Points Relative risk can be calculated for cohort studies, because the underlying incidence of the condition under study is known (the incidence in the unexposed group). For case-control studies, the underlying incidence is unknown, so relative risk cannot be calculated. Instead, an odds ratio is used. We won’t go into the calculation of an odds ratio; just understand that odds ratio quantifies risk for a case-control study as relative risk does for a cohort study.

Interpreting Relative Risk
No increase in risk in exposed group compared with unexposed group Increased risk in exposed group Decreased risk in exposed group Talking Points To interpret relative risk: Relative risk = 1: no increase in risk in the exposed group compared with the unexposed group Relative risk > 1: increased risk in the exposed group Relative risk < 1: decreased risk in exposed group Therefore, the data that triggered the 1995 pill scare showed that women who took 3rd generation OCs had a risk of VTE 2 times that of women who took 2nd generation OCs.

The alternative to effective contraception is unintended pregnancy, which is in itself associated with risk. In the US approximately 470 women die each year from pregnancy-related causes (11.8 per 100,000 live births) This slide shows one of the risks associated with unintended pregnancy: venous thromboembolism.

Causes of Risk Misperception about Hormonal Contraceptives
Talking Points Risk misperception about combined hormonal contraceptives can exist for patients or providers. Risk misperception is probably caused by a number of factors, including Lack of understanding of statistics Psychological factors Media influences Factors that affect risk perception and interpretation Statistics is a complicated field, requiring a baseline of mathematical education that many people do not have. For this reason, it may be challenging for patients to fully comprehend the mathematical basis of risk calculations about effectiveness or adverse events associated with combined hormonal contraceptives. Psychological factors may influence a woman’s perception of risk. For example, ambivalent feelings about women’s sexuality—due to cultural or other influences—may induce a woman to avoid more effective contraceptive methods if they require advance planning. We’ll discuss in more detail the influence of media and other factors that affect risk perception and interpretation. - - - Original content for this slide submitted by the Clinical Advisory Committee for You Decide: Making Informed Health Decisions about Hormonal Contraception in May 2006, a joint program of ARHP and Planned Parenthood® Federation of America (PPFA).

Weighing the Risks & Benefits
Talking Points It is important to understand that for most women, the non-contraceptive benefits of combined hormonal contraceptives outweigh the potential risks. That said, smoking, hypertension, obesity, and diabetes are risk factors that must be considered when evaluating risks associated with combined hormonal contraceptives.

Pill Generations High court ruling 2002 –failed to show increase of VTE odds ratio between 3rd and 2nd generation Medicines Committee Advice 1999 The absolute risk of VTE taking third generation pills is very small & is much less than the risk in pregnancy. There is a small excess risk of 10 cases of VTE per 100,000 women compared with those taking second generation pill. Provided women are fully informed of the small risks & do not have medical contraindications, it should be a matter of clinical judgement and personal choice which COC is prescribed.

Progestins are best classified into Gonanes (Levonorgestrel, desogestrel, gestodene and norgestimate) Estranes (Norethindrone, Lynestrenol) Estranes and gonanes differ in : Bioavailability The greater the posthepatic bioavailability , the lower is the dose needed to be used. Only norethindrone, gestodene and levonorgetrel are active as such. Other progestins are prodrugs and so need to be given in higher dosages to compensate for hepatic biotransformation.
42
1st, 2nd and 3rd Generation Progestins
Serum half-lives Long serum half life is associated with more consistent cycle control and greater contraceptive protection in the event of missed pills. The shortest half life is that of norethindrone (7 hours) and the longest is that of levonorgestrel (15 hours). Relative binding affinity to the progesterone receptors. Greater relative binding affinity means that a smaller dose is needed for a consistent clinical effect to be achieved. Among OC progestin, levonorgestrel has the highest relative binding affinity followed by the active metabolite of the desogestrel. Strong Evidence suggests that all progestins effectively reduce free testosterone levels by 40-50% in average women.
43
1st, 2nd and 3rd Generation Progestins
All OCs inhibit the 5 -reductase in the skin resulting in lower levels of active dihydrotestosterone with subsequent better control of acne and hirsutism. There is no evidence to support that one class of progestin is superior to another with regard to androgen related conditions.
44
Anti-androgenic Progestogens Cyproterone Acetate-(in Diane/ Brenda)
Anti-androgen with progestogenic qualities Binds strongly to androgen receptors and prevents action of testosterone Major indication is in those with significant hirsutism or acne Takes 3 months for effect on acne and 6 months for effect on hirsuitism Can accelerate effect by adding in extra Androcur initially
45
Anti-androgenic Progestogens Drosperinone-(in Yasmin)
Yasmin-Ethinyloestradiol 30 µg and drospirenone 3mg Drosperinone related to Spironolactone Has mild diuretic effects- less fluid retention Antiandrogenic effects Weight Loss ?- mainly due to fluid loss-0.5 kg over 12 months

Emergency Contraception
WHO Study in compared the older Yuzpe method using high dose Combined Pills (Nordiol 2 X 2) with high dose progestogen-only regime(0.75 mgs LNG X2) The POP regime was found to be more effective with less side effects. Yuzpe and the WHO trial both used divided doses (12 hours), up to 72 hours after USI

52
Hot off the Presses! Lancet article published December 2002 showed
POP emergency contraception retained some effectiveness up to 120 hours (5 days) after unprotected sex A single stat dose of 1.5 mgs seemed to be slightly more effective than the divided dose Von Hertzen H et al. Lancet 2002; 360: FPA Health has now changed its Clinical Protocols on ECP to reflect this study TGA recently approved ECP as a pharmacist-supplied item
53
Absorption of oral preparations
hormones are absorbed from the upper small intestine. peak plasma levels reached within 2 hours vomiting within 2 hours of ingestion reduces the amount of hormones absorbed, & missed pill instructions should be followed during the attack and for the next 7 days. in the case of combined oral contraception, the pill free interval should be omitted if less than 7 pills remain in the packet. diarrhoea (unless severe) is unlikely to affect drug levels; there are no studies showing any pharmacological basis for failure.
54
Metabolism in the liver
Drugs which increase metabolism of EE and progestogens, during and up to one month after stopping treatment. anticonvulsants (with the exception of sodium valproate, clobazam, vigabactrin, gabapentin and lamotrigine), griseofulvin, barbiturates, ritonovir (and possibly other protease inhibitors amprenavir, indinavir, lopinavir, nelfinavir, and saquinavir)
55
Use of COC and liver enzyme inducing drugs
COC users need at least 50mcg of EE to ensure contraceptive action efficacy may be further increased by tricycling, and/or decreasing the pill free interval common practice (for which there is no evidence) to consider the absence of break through bleeding as a marker of sufficient contraceptive cover in this situation.
56
Use of progestogens and liver enzyme inducing drugs
POP users should switch to injectables or another form of contraception IUS no evidence of interaction most of its progestogenic effect is directly on the endometrium with little absorption EHC experts suggest that the dose is increased by 50% levonorgestrel 0.75 mg tablets or 3 tablets stat injectable progestogen methods are often given 2 weeks early data sheet for Depo-Provera states that no adjustment is needed
57
Powerful enzyme inducing drugs
Rifampicin and rifabutin are such powerful enzyme inducers that even short courses of 2 days of the former (used as prophylaxis in close contacts of cases of Neisseria meningitis) reduce contraceptive efficacy for a month. Longer courses may have an interactive effect for up to 2 months after stopping. Oral contraceptive methods should not be relied on during this time. The same principles should apply to injectables, implants and IUS
58
Broad spectrum antibiotics
EE is excreted into the bile; and reabsorbed into the circulation from the colon broad-spectrum antibiotics (mainly ampicillin and tetracycline)affect these bacteria accepted UK practice that COC used alone is unreliable while taking short courses of penicillins and tetracyclines and for 7 days after stopping; the pill free interval should be omitted if less than 7 pills remain in the pack when the drug is continued beyond 2 weeks, the gut flora appear to become resistant, allowing a return to reabsorption of EE. effectiveness of the POP, progestogen-only emergency contraception, injectables, implants and IUS are not affected by broad spectrum antibiotics.
59
The only drugs known to have a clinically significant impact on contraceptive efficacy
rifampicin and rifamycin, griseofulvin, some anticonvulsants topiramate, barbiturates, carbamazepine, primidone ritonovir, and in some women short courses of tetracyclines and ampicillin.

History of Intrauterine Contraception
1909: Grafenberg develops ring-shaped IUD device 1967: "T" shaped device developed 1962: 1st international conference on IUDs; designs for plastic spiral and plastic loop presented Talking Points The first version of the modern intrauterine contraceptive was developed in 1909 by a German gynecologist and sex researcher named Ernst Grafenberg. It was a ring-shaped device made of silver wire and silkworm gut. It wasn’t widely used until the 1920s. Plastics became widely available in the 1950s and became very useful in the development of new forms of intrauterine contraception. A flurry of activity at The Population Council resulted in the First International Conference on Intrauterine Contraception in 1962, where Drs. Marguiles and Lippes introduced the intrauterine plastic spiral and intrauterine plastic loop. 1964: Bernard Berelson, vice president of The Population Council, at the Second International Conference states, “This simple device can and will change the history of the world.” 1967: Scientist at The Population Council developed "T" shaped device. Since 1960, nine intrauterine contraceptives have appeared on the US market. References Richter R. Ein mittel zur verhuntung der Konception. Deutsche Med Wochenschr. 1909;35: Grafenberg E.

1988: Copper T 380 IUD available in the U.S. Today: Only 2% of US women use IUDs 2001: LNG IUD available in the U.S. Talking Points The copper T IUD (brand name ParaGard®) was approved by the Food and Drug Administration (FDA) in 1984 and has been available for use in the United States since 1988. Since 2005, DuraMed Pharmaceuticals, Inc., a division of Barr Pharmaceuticals, Inc., has marketed ParaGard. In 2000, the levonorgestrel (LNG) IUD (brand name Mirena) became available in the US. It is marketed by Berlex Inc. Reference Mosher WD, Martinez GM, Chandra A, et al.

Dispelling Common Myths About IUDs
In fact, IUDs: Are not abortifacients Do not cause ectopic pregnancies Do not cause pelvic infection Do not decrease the likelihood of future pregnancies Are not large in size Talking Points IUDs are not abortifacients; they prevent fertilization. IUDs do not increase the risk of ectopic pregnancy; rather, they decrease the risk of both ectopic and intrauterine pregnancy. However, IUDs are more efficient at preventing uterine than ectopic pregnancy, so that compared with other methods, a higher fraction of pregnancies that occur with an IUD are ectopic. A survey of ob/gyns shows that although attitudes toward the safety and effectiveness of the IUD are very positive, most respondents believe that a long-term causal relationship exists between the modern copper T IUD and PID. The truth is that IUD use, in properly selected patients, does not increase the risk of PID. Untreated pelvic infection is the most common cause of infertility; IUD use is not associated with infertility. The 2001 New England Journal of Medicine article by Hubacher et al., as well as others, confirms the overall benign impact on women who use copper IUDs. Some women are hesitant to use the IUD because they perceive it to be larger than it actually is. In truth, both types of IUD are small and can fit in the palm of the hand.

Dispelling Common Myths About IUDs (continued)
In fact, IUDs: Can be used by nulliparous women Can be used by women who have had an ectopic pregnancy Do not need to be removed for PID treatment Do not have to be removed if actinomyces-like organisms (ALO) are noted on a Pap test Talking Points: A 4-year study found that IUD failure and expulsion rates were lower for nulliparous than parous women. Another study that evaluated three types of IUDs in nulliparous women found low failure and expulsion rates. According to the World Health Organization’s Medical Eligibility Criteria for Contraceptive Use, nulliparity is considered a condition for which the advantages of using an IUD generally outweigh the theoretical or proven risks. IUD use in women with a previous ectopic pregnancy is appropriate but reflects off-label use. IUD users who develop an STI or PID should be tested for relevant organisms and treated with appropriate antibiotic therapy. Clinical guidelines state that removal of the IUD is not necessary unless symptoms fail to improve within 72 hours of the start of treatment. Actinomyces-like organisms (ALO) normally exist in the female genital tract and are sometimes identified on Pap tests. Current recommendations state that symptomatic women with a finding of ALO from a Pap or other test should be treated with appropriate antibiotics and the IUD should be removed (after the patient has begun antibiotics). Asymptomatic women require neither IUD removal nor antibiotic therapy. References: Duenas JL, Albert A, Carrasco F. Intrauterine contraception in nulligravid vs. parous women.

Safety: IUDs Do Not Cause PID
PID incidence for IUD users is similar to that of the general population Risk is increased only during the first month after insertion Preexisting STI at time of insertion, not the IUD itself, increases risk Talking Point The presence of a preexisting sexually transmitted infection (STI) at time of insertion, not the IUD itself, increases the risk of PID.

Rate per 1,000 woman years N = 20,000 women 1.6 9.25 <21 days of use 21 days - 8 years of use Talking Points Longer duration of IUD use is associated with a lower rate of pelvic inflammatory disease. Among approximately 20,000 women using the device for 21 days to 8 years, incidence of the disease was approximately 1 per 1000 woman-years, as opposed to a rate of nearly 10 in 1000 woman-years among women using the IUC for 20 days or less.

Risk of Fetal Abnormality
IUD is extra-amniotic No increase in birth defects for copper IUD Talking Points As shown in case-series reports, there is no increase in the incidence of birth defects in infants born at term with a copper or progesterone IUD left in place for the duration of the pregnancy. There are no data for the levonorgestrel intrauterine contraceptive. In a case-control study reported by the Centers for Disease Control and Prevention, IUDs left in place during pregnancy were not associated with an increased incidence of limb reduction defects in infants. This evidence suggests that there is no causal association between the retention of an IUD during pregnancy and an increased risk of birth defects. References Atrash HK, Frye A, Hogue CJR.

Safety: IUD Does Not Cause Infertility
IUD is not related to infertility Chlamydia is related to infertility Tubal infertility by previous copper T IUD use and presence of chlamydia antibodies, nulligravid women Talking Points Background: Previous studies of IUDs, many no longer in use, suggested that copper IUDs might cause tubal infertility, decreasing the use of this method in nulligravid women. Hubacher et al. enrolled 1,895 women in a case-control study: 358 women with primary infertility with tubal occlusion documented by hysterosalpingogram, 953 women who were infertile without tubal occlusion (infertile controls), and 584 primigravid women (pregnant controls). Information was obtained about the women’s past use of contraceptives including copper IUDs, previous sexual relationships, and history of STIs. Each subject had antibody testing for Chlamydia trachomatis. Stratified analysis and logistic regression analyses were employed. Results: Odds ratio for tubal occlusion associated with previous use of a copper IUD was 1.0 (95% CI, 0.6–1.7) using infertile controls. When the primigravid women served as controls, the odds ratio was 0.9 (95% CI, 0.5–1.6). Odds ratio for tubal occlusion associated with chlamydia was 2.4 (95% CI, 1.7–3.2). Conclusions: Previous use of a copper IUD is not associated with increased risk of tubal occlusion among nulligravid women; rather, chlamydial infection is.

Safety: IUDs May Be Used by HIV- Positive Women
No increased risk of complications compared with HIV-negative women No increased cervical viral shedding WHO Category 2 rating Talking Points A 1999 study in Kenya found that copper IUD insertion did not significantly change the shedding of HIV-infected cervical cells. WHO gives both the copper T and the levonorgestrel IUD a Category 2 medical eligibility rating, suggesting that the benefit of women with HIV infection using an effective contraceptive method outweighs potential risk of infection. Category 1: A condition for which there is no restriction for the use of the contraceptive method. Category 2: A condition where the advantages of using the method generally outweigh the theoretical or proven risks. Category 3: A condition in which the theoretical or proven risks usually outweigh the advantages of the method. Category 4: A condition which represents unacceptable health risk if the method is used (i.e., contraindications). References World Health Organization.

IUD Insertion After Spontaneous or Induced Abortion
May be safely inserted immediately after spontaneous or induced abortions Not recommended after septic abortion Talking Points Intrauterine contraception may be safely inserted immediately after spontaneous or induced abortions of a routine nature. Event rates following first-trimester terminationexpulsion, pregnancy, and removals for medical reasonsare comparable to those found in studies in which the device was inserted during or immediately after menses. The shorter the period of gestation at the time of spontaneous or induced abortion, the lower the event rates after IUD insertion. Insertion of a copper T IUD is contraindicated after septic abortion. Package labeling for ParaGard recommends that insertion of a copper T IUD be delayed until involution of the uterus is complete.

IUD for Postpartum Use May be safely inserted in postpartum women
Copper T IUD LNG IUD Within 48 hours postpartum OR After 4 weeks once uterus is involuted 6 weeks postpartum Talking Points Many clinicians postpone insertion of intrauterine contraception until 12 weeks postpartum because of concerns that earlier insertion may lead to higher rates of expulsion and more complications. However, copper T IUDs may be inserted safely as early as 4 weeks postpartum. Some suggest that the IUD may be safely inserted immediately after delivery of the placenta. Immediate postpartum insertion provides an opportunity for women to secure effective contraception at a convenient time. Early postpartum insertion—between 48 hours and 4 weeks postpartum—is associated with a higher rate of expulsion and perforation and is not generally recommended. Package labeling recommends that IUDs should not be inserted until involution of the uterus is complete. References Treiman K, Liskin L, Kols A, Rinehart W. IUDs—an update.

IUD Use During Lactation
Effectiveness not decreased Uterine perforation risk unchanged Expulsion rates unchanged Decreased insertional pain Reduced rate of removal for bleeding and pain LNG comparable to copper T in breastfeeding parameters Talking Points Chi et al. assessed copper T IUD use during lactation in 559 breastfeeding women and 590 non-breastfeeding women. Results indicate that the device is at least as effective in women who are breastfeeding as in those who are not. Expulsion rates are similar in lactating and non-lactating women. However, pain at insertion as well as removals for pain and bleeding are lower in women who are breastfeeding than in those who are not. In this study, no cases of uterine perforation occurred in either group. A more recent study found that the LNG IUD is comparable to the copper T in rates of breastfeeding continuation, complete weaning, full breastfeeding, and partial breastfeeding and did not affect infant growth or development.

Checklist for STI Risk Assessment
Circle appropriate answer Yes No Is the client < 25 years old? 1 Is she currently living apart from her husband or partner? During the last year, has she had bleeding between periods or bleeding or spotting within 24 hours after sex? Is her school education < secondary level? Talking Points An algorithm was created for categorizing women’s risk for STIs before insertion of an IUD. The authors found it performed reasonably well at identifying women at low current risk of cervical infection. It performed as well as more complex algorithms and without a physical exam. Conclusion: The algorithm can be used in identifying appropriate candidates for an IUD in settings of moderate to high STI prevalence and where laboratory testing for STIs is not available.

Scoring STI Risk Assessment
Recommended action Low cervical infection population (<10%) High cervical infection population (=10%) Counsel/refer for IUD insertion without any reservations If score is 0–2 If score is 0 Consider presumptive treatment for chlamydia/ gonorrhea (if available) or counsel/refer to use another contraceptive If score is 3+ If score is 1+ Talking Points Because the overall prevalence of cervical infection may vary widely by region, the authors suggest placing the total score into a low cervical infection category or a high cervical infection category, depending on the background prevalence of cervical infection in a particular clinic population. The algorithm suggests the following actions based on the total score: Counsel/refer patients for IUD insertion if your clinic has a low cervical infection prevalence and they have a score of 0–2, or if you have a high cervical infection population and they have a score of 0. Consider treating patients presumptively for STIs if available or counseling/referral to another birth control method if their score is 3+ in the former population (low cervical infection prevalence) or 1+ in the latter population (high cervical infection prevalence).

LNG IUS: Mechanism of Action
Fertilization inhibition: Cervical mucus thickened Sperm motility and function inhibited Endometrium suppressed Weak foreign body reaction induced Ovulation inhibited (in some cycles) Talking Points The picture on the slide is just a schematic, so it is not anatomically proportional. The mechanism of action of the levonorgestrel intrauterine system is similar to that of LNG implants or LNG-containing mini-pills. As with other methods, thickening of the cervical mucus (1) and inhibition of sperm motility and function are the primary role (2). The LNG intrauterine system does not usually inhibit ovulation (3), but the pregnancy rate and the ectopic rate are extremely low, suggesting that a primary endometrial effect as the mechanism of action is unlikely. The endometrial atrophy which is a consequence of the high endometrial levels of LNG leads to the substantial decrease in menstrual flow and absence of bleeding in some women noted in users of this form of intrauterine contraception. A weak foreign-body effect is also noted. It is important to some patients that the LNG IUS mechanisms of action are all pre-conception. They prevent fertilization rather than disrupt implantation (a common misconception). Sources Jonsson B, Landgren B-M, Eneroth P. Effects of various IUDs on the composition of cervical mucus.

LNG IUS: Comparison to Sterilization
Talking Points Because the LNG IUS failure rate is comparable to that of sterilization, it could be viewed in this context as reversible sterilization, not just reversible contraception. Even though this schematic depicts a difference, there is no significant statistical difference between the Nova T and LNG IUS. These data are from the largest study. Other studies have even lower failure rates. Sources Andersson K, Odlind V, Rybo G.

124
Plasma Concentrations of Levonorgestrel
Talking Points The graph on the slide is a schematic that contrasts the plasma concentrations of “bolus” administration of oral mini-pills and combined OCs with the sustained release of LNG that occurs in the IUS and the LNG implant. At this level of plasma concentration, ovarian hormonal function is maintained. About 85% of cycles are ovulatory at the end of one year, and estrogen levels are normal. As noted earlier, although plasma concentrations are low, endometrial concentrations are high. The effects of the hormone are thus targeted to where they are needed, not spread systemically. With the low-dose LNG IUS, LNG is detected in the serum 15 minutes after insertion. After an initial higher concentration, LNG reaches a steady state in several weeks. LNG IUS has a lower plasma concentration than implants. For short periods, combined OCs produce serum concentrations 50 times those of the low-dose products.

Endometrial suppression effect is not immediate Takes three months for full effect on the endometrium Spotting is common during this time Talking Points The effects of LNG IUS on menstrual bleeding are comparable to climbing a mountain. The spotting can be rough going for the first three months, but once the patient gets past that time, the bleeding patterns are very acceptable.

LNG IUS: Potential Contraindications
Pregnancy or suspicion of pregnancy Active cervical or endometrial infections Uterine anomaly Complete list included in the package labeling Talking Points Pregnancy is a contraindication whether it is known or suspected. The uterine abnormality may be a distorted uterine cavity, either congenital or acquired. Infected abortion is a contraindication only if it occurred within the last three months. Any bleeding of unknown etiology is included.
137
LNG IUS: Potential Complications
Expulsions Most occur during the first six months after insertion The five-year cumulative expulsion rate is 4.9 per 100 women Perforations Occur at the time of insertion Rare events, fewer than one per thousand Talking Points Expulsion rate higher immediate post-abortion than interval insertion No data on immediate post-partum insertion Recommend insertion six weeks post-partum Source Andersson K, Odlind V, Rybo G.

LNG IUS: The Inserter
140
LNG IUS: Insertion Different insertion technique than other intrauterine contraception New, one-handed insertion Requires hands-on training Efficacy and user continuation dependent on skillful insertion Talking Points The principal difference in insertion between the LNG IUS and other is the IUS inserted through the cervix with T arms folded upward, and copper devices are inserted with the T arms folded down. The two types of intrauterine contraception have very different insertion techniques and devices. Well-trained providers will have lower expulsion rates and fewer complications.
143
LNG IUS: Counseling Efficacy Return to fertility Side effects
Changes in bleeding patterns Non-contraceptive health benefits Safety Insertion and follow-up Talking Points Counseling for the LNG IUS should include discussion about non-contraceptive health benefits such as reduction in bleeding, prevention of anemia, benefits of hormone therapy, mitigation of tamoxifen-induced endometrial affects Reduction in bleeding is more than a “side effect” of this product. It may be considered a health benefit to many women and it is useful to present it to the patient in this context.

LNG IUS Counseling: Absence of Bleeding
Local effect No proliferation of endometrium This is expected. It is not a sign of: Pregnancy Ovarian or pituitary dysfunction Menopause Rapid return to menstruation after removal Talking Points Patients should understand that no individual can be guaranteed a 90% reduction in blood loss; that is a group figure. However, marked reduction is likely for all women. Differentiate between bleeding and spotting. Many patients may be confused and perceive spotting as bleeding. Understanding what spotting is and that it is a short-term problem can help motivate continuation of use.

151
LNG IUS Counseling: Insertion
Steps in the insertion process Pelvic and speculum exam Sensations produced by tenaculum Paracervical anesthesia, if needed Sensations of IUS as it is inserted Measures you will take for her comfort Talking Points Briefly describe the steps during the insertion process, including sensations she might experience. The clinician can provide an overview of these before the insertion as well as keep her informed of the process along the way. Letting the patient know she has permission to ask the clinician to slow down or stop may give her a degree of comfort for having some control during the insertion procedure. If there are other comfort measures that the clinician uses—such as offering paracervical anesthesia—describe these to the patient as well.
152
LNG IUS Counseling: Post-Insertion
Schedule a follow-up visit at 1 – 3 months post-insertion Check for partial or complete expulsion Address any questions or concerns Talking Points A follow-up visit can be scheduled from one to three months to check the placement of the device. Most importantly to determine if she has questions or concerns about her method. If she is unhappy with the system or experiencing side effects, provide appropriate counseling. Reassure her when side effects will diminish and let her know she can discontinue the method if she continues to be unhappy with it.

Myth: IUD Prevents Implantation
Most evidence now suggests that all IUDs induce a foreign body reaction that is spermicidal, preventing fertilization Today’s intrauterine contraceptives have other mechanisms of action that prevent fertilization Talking Points Studies found an absence of any detectable hCG in the sera of 30 users of non-medicated IUDs over a thirty-month period, which suggests that disruption of implantation is not a major mechanism Other mechanisms of action that prevent fertilization include thickening the cervical mucus and creating a barrier to sperm penetration.

Tubal Sterilization: FDA-Approved Methods
The most widely used occlusion methods are typically performed on the isthmic portion of the fallopian tube: Partial salpingectomy Clips Silicone rings Electrocoagulation Micro-insert Talking Points In a partial salpingectomy the fallopian tubes are cut and tied with suture material. The Pomeroy technique, a widely used version of partial salpingectomy, involves tying a suture around the base of a small loop of the tube and cutting off the top segment of the loop. As the tube heals, the suture is absorbed and the two ends separate. This technique requires no special equipment; it can be performed with only scissors and suture. Any obstetrician/gynecologist, family practitioner, or surgeon with operating privileges can perform this procedure, as can physician assistants in some states. With clips, the fallopian tubes are blocked by clamping down and cutting off the blood supply, causing a small amount of scarring or fibrosis that prevents fertilization from occurring. The two most common clips are the Filshie clip, made of titanium, and the Hulka clip, made of plastic. Clips are easy to use, but each type requires a special applicator. They have the highest rates of tubal reversal because they destroy the smallest amount of Fallopian tube. Silicone rings, like clips, also block the tubes mechanically. A small loop of the fallopian tube (much like the Pomeroy procedure) is created, and the stretched ring is advanced over the loop to the base. When the ring is released, it stops the blood supply to that small loop, with resultant scarring that blocks passage of the sperm or egg. The most common of these is the Falope Ring, although the Yoon ring is also popular. Electrocoagulation uses electric current to coagulate or burn a small portion of each fallopian tube. Unipolar coagulation passes current through the forceps applied on the tubes, and the current leaves a woman’s body through an electrode placed under her thigh. Because it was associated with sparking, this approach is no longer recommended. In bipolar coagulation, current passes only between the two ends of the forceps. Bipolar coagulation is safer than the unipolar technique, but it is associated with higher ectopic pregnancy rates than the Pomeroy procedure. - - - Original content for this slide submitted by the ARHP Clinical Advisory Committee for New Developments in Contraception: Permanent Options for Women in October Original funding received from Conceptus, Inc. through an unrestricted educational grant.

Transcervical Sterilization: Advantages to the Patient
No incision Absence of a scar preserves privacy Less invasive Less discomfort Faster recovery Efficacy Talking Points: For women with medical conditions such as heart disease and obesity procedure may be safer, partly because of routine use of local anesthesia, particularly. Some of these women are ineligible for conventional tubal sterilization. Because no incision is necessary, it's less invasive, women have less discomfort and recover faster, and the absence of a scar preserves their privacy. - - - Original content for this slide submitted by the ARHP Clinical Advisory Committee for New Developments in Contraception: Permanent Options for Women in October Original funding received from Conceptus, Inc. through an unrestricted educational grant.

Micro-Insert: Mechanism of Action
Expansion of outer coil for acute anchoring Space filling/mechanical blockage of tubal lumen Tubal occlusion by tissue in-growth into and around the micro-insert Long-term nature of tissue response not known beyond 24 months Talking Points: There is a three fold explanation for the Essure device’s mechanism of action: First the expandable outer coil is responsible for acute device anchoring; second the device provides both space filling and mechanical blockage of the tubal lumen; and finally occlusion is achieved as a result of a tissue in-growth from the tubal mucosa into and around the Micro-Insert.

The Introduction of a New Contraceptive Method to the Market
New contraceptive methods usually considered newsworthy Consumers increasingly well informed around options and their rights to informed choice The growing number of options available makes it increasingly difficult for health practitioners to do justice to the pros and cons of each method in the available time.
192
Contraceptive Counselling
The trend to an increase in available contraceptive options seems likely to continue along with an acceptance that the consumer has a right to accurate, comprehensive and balanced information from their health provider Any clinician attempting to counsel a patient around contraceptive choice will need to put this counselling within the broader context of the person’s past experiences, cultural background and belief systems A person will rarely persist with a contraceptive method they do not feel is right for them - they will simply feel their practitioner has not heard them In the area of contraception the clinician is often the adviser, sometimes the supplier, but, if they have any sense at all, never the decider.
