1 Newer Intra-Uterine Contraceptive Devices

3 Family Planning alone could bring more benefits to more people at less cost than any other single technology now available to the human race. UNICEF

4 Contraceptive Use Indian Scenario There has been consistent improvement in the levels of contraceptive use in the country over time. However, these changes have not necessarily brought along corresponding decline in fertility levels for various reasons The data from the NFHS I and II indicate that the contraceptive prevalence rate for India was about 41 per cent during that increased to slightly over 48 per cent by the end of the last century, an increase of 7 per cent points in 6 years which is not significant and is the main reason for our mammoth population growth

5 Unintended vs. Intended Pregnancies Henshaw SK. Fam Plann Perspect. 1998;30: Unintended 49% Intended51% Unintended births (22.5%) Elective abortions (26.5%)

6 Unmet Need in India Millions of women would prefer to avoid becoming pregnant either right away or ever, but are not using any contraception These women have an unmet need –Awareness –Access –Availability Unmet need for family planning (NFHS-3)Unmet need for family planning (NFHS-3) Spacing 7.3% Limiting 7.3% Total 14.6%

7 Everything changes continually. What is history but a record of change? Mahatma Gandhi

8 Evolution of IUCDs 1 st generation : Lippes Loop 2 nd generation : copper containing 3 rd generation : progesterone containing Progestasert Levonorgestrel (Mirena) 4 th generation : frameless IUD GyneFix (copper) FibroPlant ( levonorgestrel)

9 Evolution of Cu-IUCD 2nd generation : copper containing Cu-T 200 Multi-load 250 –375 Nova –T Newer Cu-380A

10 Currently there are 100 million IUCD users in the world, 80 % of them are in China

11 IUD: Work-up History: –STDs, Sexual History, Ectopic Examination: – Size / Configuration of Uterus –Cervical Cultures –Pap Smear Counseling

12 IUD: Mechanisms of Action NOT ABORTIFACIENT!!!!!!!! Prevents Conception –local Foreign body reaction –Sperm Transport Inhibited –Sperm Survival / Capacitation Diminished Prevents Implantation

13 Cu IUD typically comprise a solid plastic frame loaded with copper wire and/or copper sleeves very effective –(pregnancy rates <2%) Once inserted, protects for 3-10 years depending on type of IUD Easy to insert and remove Does not protect from STDs

14 New Cu-IUD: Overview ParaGard (CuT380A) Very Effective (~ TL) Reversible However- Monogamy Essential Does Not Protect Against STDs Can Remain for 10 Years

15 Cu-IUD: Complications PID: Usually secondary to Insertional Contamination –Unproven Role for Prophylactic ABx Menorrhagia Expulsion Perforation (< 0.1%) Failure: IUD Should be Removed ??Ectopic

16 LNG IUS pure levonorgestrel in the vertical 20 micrograms per day into the endometrium approved for five years of use menstrual bleeding, overall a reduction by 90%

17 LNG – Mechanism of action Endometrium suppressed Cervical mucous thickening Sperm motility and function affected Weak foreign body reaction Rare cases inhibits ovulation Johnson et al, Contra: 1991,43;447 Videla-Ribero et a l, Contra:1997,46;217

18 Randomized studies Years Comparison Pearl index Reference of use n methodLNG-IUS Luukkainen et al., Nova-T0.1 Sivin et al., Cu T Faundes et al., Cu T 3800 Andersson et al., Nova-T0.1 Indian Council, Cu IUDs0 Wang et al., Norplant0.3

19 Apprehension caused by amenorrhea can be minimized by appropriate counselling User satisfaction strongly correlates with counselling Backman et al. Br J Obstet Gynaecol 2000;107:

20 LNG counseling – bleeding patterns 1-4 months irregular bleeding 2-6 months amount and duration of bleeding 20% will have amenorrhoea at the end of one year Overall significant reduction in the bleeding

21 LNG IUS Main reasons for premature removal were Bleeding problems5.4 % Amenorrhea1% Pain2.5% Acne1%

22 Benefits of local action of LNG No significant change in: –Blood pressure –Serum lipids –Coagulation factors –Carbohydrate metabolism –Liver function

28 LNG – other health benefits Reduction in Amount and duration of bleeding Incidence of ectopic pregnancies Menstrual cramps Non-contraceptive benefits Treatment of DUB and menorrhagia In HRT for endometrial protection

29 Other newer IUCDs

30 The design characteristics of the frameless IUD (fixed, frameless and flexible) are responsible for the low expulsion, high effectiveness and high continuation rates. Insertion is easy and safe in the hands of trained providers and appears to be as reliable and effective as when inserted at interval

31 GyneFix The expulsion rate of 8.4% and removal rate for bleeding and/or pain of 9.0% at 12 months within acceptable ranges for framed intrauterine devices does not affect future fertility in nulliparous and parous women Masters T, et al Eur J Contracept Reprod Health Care 2002 Jun;7(2):65-70

32 Gynefix The frameless intrauterine device (IUD) dispenses with the frame in the classical IUD and holds the device in the uterus by anchoring one end of a nylon thread in the fundal myometrium, to which copper sleeves are attached There are insufficient data to show that problems of early expulsions have been overcome with the new introducer used in GyneFix. Apart from that, the frameless device performs similarly to TCu380A, and appears to have a lower pregnancy rate in later years, although the absolute difference is small.

33 Gynefix Insertion

34 Newer IUCDs To Come T shaped LNG Gynefix Fibrofix Fibroplant

35 FibroPlant the FibroPlant levonorgestrel intrauterine system (IUS), releasing 14 microg of levonorgestrel/day. Strong endometrial suppression is the principal mechanism explaining both the effect on menstrual blood loss and the contraceptive performance of the IUS Eur J Contracept Reprod Health Care 2001 Jun;6(2):93-101

36 Conclusion Intrauterine contraception is the most cost-effective reversible method of contraception increasingly attractive due to the development of new technologies that not only enhance the performance of the intrauterine device (i.e. efficacy is now close to 100%), but also reduce the rate of expulsion and the number of removals for medical reasons Eur J Contracept Reprod Health Care 2000 Dec;5(4):
