2 s e x u a l i t y a n d u. c a Unintended pregnancies with various contraceptive methods Numbers given are pregnancies for every 1000 women during first year of use Unintended Pregnancies Adapted from Trussell et al, 2004.

3 s e x u a l i t y a n d u. c a Female reproductive system Fallopian tube Ovaries Uterus Cervix Vagina

4 s e x u a l i t y a n d u. c a Female reproductive system Fallopian tube Ovary Uterus Bladder Clitoris Urethra Vagina Cervix Rectum

5 s e x u a l i t y a n d u. c a Female menstrual cycle

6 s e x u a l i t y a n d u. c a How does it work? Causes changes in the lining of the uterus Prevents the sperm from fertilizing the egg Decreases the ability of the sperm to penetrate the cervical mucus Failure rate: 8 per 1000 women per year Intrauterine device (IUD) What is it? A T-shaped device with a copper wire around it It is inserted into the uterus by a physician in the doctors office Two threads may be felt in the vagina, so a woman can check for herself to ensure that the IUD is still in place

7 s e x u a l i t y a n d u. c a What are the advantages? 1. Long-acting contraceptive; can be left in place for up to five years 2. No daily contraceptive routine required; device provides five years of contraception 3. Does not contain estrogen 4. Does not interfere with intercourse 5. May reduce the risk of endometrial cancer 6. May be suitable for women who are breastfeeding Intrauterine device (IUD)

8 s e x u a l i t y a n d u. c a What are the disadvantages? 1. Possible side effects include irregular bleeding or spotting in the first months after insertion 2. Perforation of the uterus may occur at the time of insertion but this is rare 3. May increase menstrual bleeding or menstrual cramping 4. May be expelled from the uterus. This happens in 2–10% of IUD users 5. Does not protect against STIs Intrauterine device (IUD)

9 s e x u a l i t y a n d u. c a Female sterilization Tubal occlusion Having your tubes tied What is it? A surgical procedure to close or block the fallopian tubes Techniques include: Laparoscopy – special instruments are inserted through two tiny incisions (less than 1 cm long) in the abdomen Mini-laparotomy – also requires a small cut in the abdomen Hysteroscopy – use of a thin telescope inserted into the uterus Fallopian tubes may be blocked by using one of the following: A clip or a ring Cautery (an electric current) Removing a small piece of each tube Hysteroscopy for the insertion of tubal plugs (Essure) How does it work? The fallopian tube is blocked and therefore the sperm and egg cannot meet Failure rate: 5 per 1000 women per year EssureCauterization Clips Ligation Sites of Sterilization

10 s e x u a l i t y a n d u. c a What are the advantages? 1. No daily contraceptive routine required; nothing to remember 2. Private 3. Does not interfere with intercourse 4. No significant long term side effects Female sterilization

If pregnancy occurs, there is a higher chance that it will be an ectopic pregnancy 5. Does not protect against STIs Female sterilization

12 s e x u a l i t y a n d u. c a Female condom How does it work? Placed in the vagina before intercourse Lines the vagina completely, preventing direct contact between the penis and the vagina and preventing the exchange of body fluids Sperm is trapped in the condom, which is thrown away after intercourse A new condom should be used for each repeated act of intercourse Failure rate: 210 per 1000 women per year What is it? Soft, disposable, polyurethane sheath Available in drugstores without a prescription

13 s e x u a l i t y a n d u. c a What are the advantages? 1. Available widely without a prescription 2. No daily contraceptive routine or continued use required 3. Woman remains in charge of placement and use 4. Protects against some STIs Female condom

14 s e x u a l i t y a n d u. c a What are the disadvantages? 1. Must be available at time of intercourse 2. Requires proper insertion technique 3. Flexible inner ring may cause discomfort for some 4. More expensive than the male condom and not available in all stores 5. Makes a noise during intercourse 6. May slip or break during intercourse 7.

15 s e x u a l i t y a n d u. c a Female barrier methods How do they work? A pelvic examination by a qualified health care professional is required for fitting diaphragms and cervical caps Inserted into the vagina and fit over the cervix When positioned properly, they block the entry to the uterus so sperm cannot enter and fertilize the egg Spermicide should be reapplied for each repeated act of intercourse Failure rate: per 1000 women per year What are they? Intravaginal barrier methods that are used together with a spermicide The diaphragm is a latex dome with a flexible steel ring around its edge (a non-latex diaphragm is also available) The cervical cap is thimble-shaped silicone cap Positioned into the vagina (diaphragm) or over the cervix (cervical cap) before intercourse Must be left in the vagina for 6–8 hours after intercourse Cervical Cap Diaphragm Diaphragm and Cervical Cap

16 s e x u a l i t y a n d u. c a What are the advantages? 1. Does not contain hormones 2. Can be used by women who are breastfeeding 3. Some protection against certain STIs Female barrier methods
