Landscape of reversible long-term
contraception• The contraceptive landscape in the US is continuing to change
• Several options are currently available– Copper T IUD– Levonorgestrel-releasing IUS– Single-rod progestin-only implant
IUD=intrauterine device; IUS=intrauterine system
![Page 4: Long-Term Reversible Contraception :](https://reader035.fdocuments.in/reader035/viewer/2022062407/56812de4550346895d933b9e/html5/thumbnails/4.jpg)
IUDs and implants currently available in
the United States
*Data suggest that this device may be effective for up to 7 years. NA=not available. Adapted from Peterson HB et al. N Engl J Med. 2005; 353:2169-2175.

Single-rod etonogestrel
(progestin)-releasing implant
• Implantable contraception has recently returned to US
• Highly effective, convenient, long-acting method of contraception
• Provides “insert it and forget it” contraceptive efficacy for up to 3 years
![Page 7: Long-Term Reversible Contraception :](https://reader035.fdocuments.in/reader035/viewer/2022062407/56812de4550346895d933b9e/html5/thumbnails/7.jpg)
Copper T IUD
• FDA recently liberalized package labeling for the copper T IUD– Nulliparous and multiparous women now deemed
appropriate candidates– Restrictive language regarding a history of pelvic
inflammatory disease has been removed
• Highly effective, convenient IUD• Approved for up to 10 years of use
![Page 8: Long-Term Reversible Contraception :](https://reader035.fdocuments.in/reader035/viewer/2022062407/56812de4550346895d933b9e/html5/thumbnails/8.jpg)
Levonorgestrel-releasing IUS
• New reports of off-label noncontraceptive applications of levonorgestrel-releasing IUS– Effective for menorrhagia, including that
associated with fibroids1-6 – Efficacy for symptoms of uterine adenomyosis7
– Comparable GnRH-a for symptomatic pelvic endometriosis8

Contraception and compliance
• Compliance is difficult with contraception that requires daily attention
• Need to move toward “forgettable” contraception
• All 3 methods being discussed provide highly effective contraception without the attendant risks and irreversibility of sterilization
![Page 10: Long-Term Reversible Contraception :](https://reader035.fdocuments.in/reader035/viewer/2022062407/56812de4550346895d933b9e/html5/thumbnails/10.jpg)
Use of IUDs: contraception and beyond
• Many progestin-releasing IUDs are placed off-label for noncontraceptive benefits– Treating menorrhagia, including that associated
with uterine fibroids
• Patients can achieve their goals– Long-term, highly effective, convenient birth
control– Treatment of heavy bleeding without an invasive
and irrevocable surgical procedure
![Page 11: Long-Term Reversible Contraception :](https://reader035.fdocuments.in/reader035/viewer/2022062407/56812de4550346895d933b9e/html5/thumbnails/11.jpg)
Case 1: Contraception and relief of menorrhagia
• Busy 29-year-old lawyer with 6-month-old child
• Thinking of becoming pregnant again in several years
• Heavy menstrual flow and an irregular but not grossly enlarged uterus on bimanual exam
• Ultrasound reveals several small intramural fibroids
![Page 12: Long-Term Reversible Contraception :](https://reader035.fdocuments.in/reader035/viewer/2022062407/56812de4550346895d933b9e/html5/thumbnails/12.jpg)
Contraceptive options that reduce menorrhagia
• Oral contraceptives or DMPA– Oral contraceptives make periods shorter and more
predictable– Amenorrhea often results with long-term injectables
• Extended-cycle rings or pills might be difficult with a busy lifestyle
• Single-rod etonogestrel-releasing implant is characterized by erratic spotting and bleeding
• Copper T IUDs lead to increased menstrual blood loss
• A progestin-releasing IUD makes sense for a woman with baseline menorrhagia
![Page 13: Long-Term Reversible Contraception :](https://reader035.fdocuments.in/reader035/viewer/2022062407/56812de4550346895d933b9e/html5/thumbnails/13.jpg)
Use of a progestin-releasing IUD for
treatment of menorrhagia• Effective in women with fibroids and normal uterine
cavities1-3
• One report also showed promising results in women with uterine cavities distorted by submucosal fibroids4
• A few small intramural fibroids should not present a problem with insertion

Important tips when inserting an IUD
• Do not open IUD package until you:– Confirm patient’s desire to proceed with insertion– Perform bimanual exam: place speculum, place
antiseptic on cervix and upper vagina, place cervical tenaculum, and sound the uterus
• In resource-poor areas where full ultrasound evaluation may not be available– Gently sweep uterine sound laterally at fundus– Ensure that IUD is placed at fundus where IUD
arms can open up comfortably and maintain correct placement

Bleeding reduction with LNG-IUS vs NSAID vs tranexamic
acid
LNG-IUS=levonorgestrel-releasing intrauterine system; NSAID=nonsteroidal anti-inflammatory. Reproduced with permission of Milsom I et al. Am J Obstet Gynecol. 1991;164:882.

NSAIDs are therapeutic but not useful as a
prophylactic• NSAIDs reduce bleeding among women with and
without organic pathology of the uterus• They are not as effective as the levonorgestrel-
releasing IUS• A Cochrane Review indicated NSAIDs are effective
for treating pain and bleeding related to IUD use1
• A large study of 2019 first-time IUD users showed that prophylactic ibuprofen had no effect on IUD removal rates due to pain or bleeding2
• NSAIDs are not recommended as a prophylactic, but rather as a therapeutic measure after insertion

Breast-feeding and combination hormonal contraception
• OB-GYNs have been comfortable recommending nonhormonal or progestin-only contraceptives to breast-feeding mothers
• WHO studies in early 1980s regarding use of combined oral contraceptives1
– Minor effects on quantity and quality of breast milk– No effect on infant growth was seen
• During early months when using the levonorgestrel-releasing IUS, very low serum levels are observed
• No problem offering any of the nonhormonal or progestin-only methods

Case 1: Resolution
• Patient chose levonorgestrel-releasing IUS• Experienced 4 months of erratic spotting• At 9 months post-insertion
– No more days of heavy bleeding– Menstrual cramps decreased substantially
• Patient satisfied with contraceptive decision
![Page 19: Long-Term Reversible Contraception :](https://reader035.fdocuments.in/reader035/viewer/2022062407/56812de4550346895d933b9e/html5/thumbnails/19.jpg)
Case 2: Birth control for the overweight
woman • A 38-year-old patient referred for sterilization
by primary care physician• Interested in long duration of use• Height: 65 inches (5’5”) tall• Weight: 190 pounds• BMI: 32
BMI=body mass index.
![Page 20: Long-Term Reversible Contraception :](https://reader035.fdocuments.in/reader035/viewer/2022062407/56812de4550346895d933b9e/html5/thumbnails/20.jpg)
Why sterilization?
• Effective nonsurgical methods exist• Laparoscopic sterilization presents technical
issues in obese women– Thick abdominal walls– Anesthesia risks– Other surgical risks
• Convenience of sterilization is appealing….• But other long-acting and efficacious medical
therapies should be explored
![Page 21: Long-Term Reversible Contraception :](https://reader035.fdocuments.in/reader035/viewer/2022062407/56812de4550346895d933b9e/html5/thumbnails/21.jpg)
DVT risk and recommended therapy
• Combination hormone contraception is associated with elevated DVT risk
• Age and obesity are also independent risk factors• Recently updated ACOG guidelines1
– Obesity in women >35 years suggests use of progestin-only and/or intrauterine contraceptives
– Discourages use of combination contraceptives• Neither the copper T IUD, the levonorgestrel-
releasing IUS, nor the single-rod progestin-only implant is contraindicated
ACOG=American College of Obstetricians and Gynecologists; DVT=deep venous thrombosis.1. ACOG, Committee on Practice Bulletins-Gynecology. Obstet Gynecol. 2006;107:1453-1472.

Case 2: 10-year follow-up
and resolution • Patient chose the copper T IUD• 10 years later at age 48, should the IUD be
removed? • Studies from the United Nations and Brazil indicate
high efficacy of copper T IUD after the 10-year window1,2
• Spontaneous fertility beyond age 45 is rare and the IUD becomes even more effective
• Keeping IUD for a few more years may be indicated

Case 3: A young woman seeking long-term contraception
• 18-year-old patient• Unintended pregnancy and abortion 16
months ago• Occurred after being prescribed oral
contraceptives• Wants information regarding long-term
contraception
![Page 24: Long-Term Reversible Contraception :](https://reader035.fdocuments.in/reader035/viewer/2022062407/56812de4550346895d933b9e/html5/thumbnails/24.jpg)
What are the options?
• Oral contraceptives have many benefits but compliance is an issue
• The patch and the ring are also options• Important to remember: a highly effective
method of birth control is important to the patient– Implant is easy to use and remove– Either IUD is also a good option– DMPA should also be considered; however
adolescent women tend to start and stop
![Page 25: Long-Term Reversible Contraception :](https://reader035.fdocuments.in/reader035/viewer/2022062407/56812de4550346895d933b9e/html5/thumbnails/25.jpg)
Bone density and DMPA
• Highly effective contraception for hundreds of thousands of US teens– May be in part responsible for declines in
pregnancy and abortions among adolescent women in the United States1
• WHO literature review determined there should be no time limitations with use of DMPA for women of any age2
• The FDA may have overreacted

IUDs, monogamy, and STDs
• Hormonal IUDs may not be neutral in terms of risk of infection
• May be positively protective• Study showed a lower risk of IUD removals
due to upper genital tract infection with hormonal IUD vs copper IUD1
• Women at risk of acquiring STDs may want to use hormonal IUD as opposed to copper IUD
STDs= sexually transmitted diseases. 1. Toivonen J et al. Obstet Gynecol. 1991;77:261-264.

Case 3: Resolution
• Patient chose etonogestrel (progestin)-releasing implant
• Experienced some unpredictable episodes of spotting and bleeding
• Understands need for condoms to protect against STDs
• At age 21 she will have to reassess because implant is only effective for 3 years
