17 The Newest Implantable: A Single Rod Etonogestrel subdermal implant 68 mgImplanon is a 3 year progestin-only subdermal implant containing etonogestrel- the active metabolite of desogestrel. It is inserted between the biceps and triceps in the non-dominant arm. It should be inserted or removed only by those clinicians who have received proper training.
18 Design of ENG Rod 40 mm 2 mm Core: 40% Ethylene vinyl acetate (EVA) 60% Etonogestrel (68 mg)Implanon is 40 mm in length and 2 mm in diameter. It is composed of a solid core of Evatane with the crystals of etonogestrel imbedded within the core. Surrounding the core is a thin layer of evatane (0.06mm thick) that controls the rate which etonogestrel is released.Rate-controlling membrane: (0.06 mm)100% EVA6

All clinicians involved were proficient and experienced with the removal and insertion techniques for both subdermal systems. As the data shows, Implanon was about 4 times faster to insert and about 5 times faster to remove.Removal*Insertion time = time needed for incision (if any) and placement; removal time = time needed for anesthesia, incision, and removal.Mascarenhas L.

22 Bone Mineral Density and ENG Rod Head-to-head study of ENG rod with non-medicated IUD (copper)No differences in BMD changes between 2 groupsAuthors concluded that although ENG rod is a progestin-only method, no bone loss occurs during useBecause some progestin-only methods cause a decrease in bone over time, a BMD study was done during the clinical trials which compared Implanon with a non- medicated copper IUD. During and at the conclusion of the study, no differences in BMD was noted between the two groups and it was concluded that Implanon has no detrimental effect on bone density. This is primarily due to the fact that although ovulation is effectively inhibited, endogenous estrogen production by the ovaries is not significantly affected.Beerthuizen R, et al. Hum Reprod. 2000;15:118–122.
23 Etonogestrel/Ethinyl Estradiol Vaginal Ring The etonogestrel/EE ring is a flexible, soft, transparent ring with an outer diameter of 54 mm and a cross section of 4 mmThe etonogestrel/EE vaginal ring is a new, highly effective contraceptive method recently approved by the FDA

25 Vaginal RingPatient ManagementPatient inserts ring and it is supposed to remain in the vagina for 3 weeksRing is removed during the fourth week, menstrual period should beginIf ring is removed or slips out of place for > 3 hrs, back-up contraception is necessary for 7 daysThe ring must be kept in place for three consecutive weeksRemove the ring three weeks after insertion on the same day of the week as it was inserted, and at about the same timeYour menstrual period will usually start two to three days after the ring is removed and may not have finished before the next ring is inserted. To continue to be protected from pregnancy, you must insert the ring one week after the last one was removed, even if your menstrual bleeding has not stoppedIt should be noted that the ring can be expelled from the vagina while removing a tampon, moving the bowels, straining, or with severe constipationIf the ring slips out and it has been out less than three hours, you should still be protected from pregnancy. The ring should be re-inserted as soon as possible. If it has been out of the vagina for more than three hours, you may not be protected from pregnancy. You must use an additional method of birth control, such as male condoms or spermicide, until the ring has been in place for seven days in a row
26 Summary Good cycle control Vaginal RingSummaryGood cycle controlIrregular bleeding was rare (2.6% - 6.4% of evaluable cycles)Withdrawal bleeding occurred (97.9% % of evaluable cycles)Compliance with the regimen was met in 90.8% of cyclesThis study demonstrated that the ring is an effective method of contraception with good cycle control. It is easy to use, well-tolerated and well- accepted by usersThe ring has a good bleeding profile. Irregular bleeding occurred in only 2.6% – 6.4% of the cycles. The irregular bleeding that occurred consisted mainly of spotting only; breakthrough bleeding was reported in only 0.4% – 1.1% of the cyclesCompliance to the regimen was high (90.8%)Roumen FJ, et al.

After 6 cycles, the overall probability of pregnancy with the patch was half that of the OC (0.6% vs 1.2%) while the method failure probability of pregnancy was nearly the same (0.4% vs 0.6%)OC416772.181.25*User failure plus method failure**Failure when taken as directedAudet M, et al.

The polyethylene is compounded with barium sulfate, making it radiopaque.A “sleeve” or reservoir on the vertical stem of the T-body contains 52 mg of levonorgestrel dispersed in polydimethylsiloxane.
