Birth Control (Contraception): Resource Overview

Birth control methods to prevent pregnancy include progestin-only pills and injections; combined estrogen and progestin pills, patches, and the vaginal ring; long-acting reversible contraception (LARC) including the intrauterine device (IUD) and implant; barrier methods including the diaphragm, sponge, cervical cap, and condom; fertility awareness including rhythm method; emergency contraception including pills and the copper IUD; and tubal sterilization. Ob-gyns, physicians whose primary responsibility is women’s health, are dedicated to providing scientific information and access to contraception for their patients.

Here are the key publications and resources for ob-gyns, other women’s health care providers, and patients from the American College of Obstetricians and Gynecologists (ACOG) and other sources.

Program: Long-Acting Reversible Contraception

ACOG’s LARC Program works to reduce unintended pregnancy in the US by providing information and guidance on the most effective reversible contraceptive methods. This page provides a broad range of materials including clinical guidance, educational materials, and notices of upcoming LARC Program meetings and events.

Committee Opinion: Increasing Access to Contraceptive Implants and Intrauterine Devices to Reduce Unintended Pregnancy

“Increasing Access to Contraceptive Implants and Intrauterine Devices to Reduce Unintended Pregnancy,” issued by ACOG in October 2015, expands the 2009 recommendation that LARC be offered as first-line contraceptive methods.

Committee Opinion: Access to Contraception 

"Access to Contraception," issued by ACOG in January 2015, reviews barriers to contraceptive access including knowledge deficits, a restrictive legal and legislative climate, and cost and insurance coverage. It also offers strategies to improve access to contraception.

Committee Opinion: Depot Medroxyprogesterone Acetate and Bone Effects

"Depot Medroxyprogesterone Acetate and Bone Effects," issued by ACOG in June 2014, addresses the association between the use of the contraceptive depot medroxyprogesterone acetate (DMPA) and the loss of bone mineral density (BMD). It emphasizes that these effects should not discourage clinicians from prescribing DMPA and provides recommendations for counseling patients.

Committee Opinion: Access to Postpartum Sterilization

“Access to Postpartum Sterilization,” issued by ACOG in July 2012 (reaffirmed 2016), notes that postpartum tubal sterilization is one of the safest and most effective methods of contraception, and calls on obstetrician-gynecologists to identify and eliminate barriers to its use. The guideline recommends that postpartum sterilization be considered an urgent surgical procedure.

Practice Bulletin: Benefits and Risks of Sterilization (members only)

“Benefits and Risks of Sterilization,” issued by ACOG in February 2013 (reaffirmed 2015), reviews the evidence for the safety and effectiveness of female sterilization in comparison with male sterilization and other forms of contraception.

Practice Bulletin: Emergency Contraception (members only)

“Emergency Contraception,” issued by ACOG in September 2015, provides clinicians with evidence-based guidelines for the use of emergency contraception. The levonorgestrel-only regimen is more effective and associated with less nausea and vomiting than the combined estrogen-progestin regimen. The copper IUD is another effective option.

Practice Bulletin: Long-Acting Reversible Contraception: Implants and Intrauterine Devices

“Long-Acting Reversible Contraception: Implants and Intrauterine Devices,” issued by ACOG in November 2017, provides evidence-based guidelines, including appropriate candidate selection for the use of IUDs and contraceptive implants, the most effective reversible contraceptives.

Committee Opinion: The Limits of Conscientious Refusal in Reproductive Medicine

“The Limits of Conscientious Refusal in Reproductive Medicine,” issued by ACOG in November 2007 (reaffirmed 2016), considers the issues raised by conscientious refusals in reproductive medicine, including contraception. In the provision of services, the guideline emphasizes, the patient’s well-being must be paramount.

Committee Opinion: Brand Versus Generic Oral Contraceptives

“Brand Versus Generic Oral Contraceptives,” issued by ACOG in August 2007 (reaffirmed 2015), acknowledges that generic oral contraceptives approved by the FDA have been shown to be bioequivalent and pharmaceutically equivalent to the branded product. However, because of possible effects on patient compliance and other considerations, ACOG supports patient or clinician requests for branded oral contraceptives.

Committee Opinion: Over-the-Counter Access to Oral Contraceptives

“Over-the-Counter Access to Oral Contraceptives,” issued by ACOG in October 2019, weighs the risks versus the benefits of over-the-counter access to oral contraceptives. The guideline concludes that oral contraceptives should be available over-the-counter.

Committee Opinion: Access to Emergency Contraception

“Access to Emergency Contraception,” issued by ACOG in July 2017, discusses barriers to access to emergency contraception methods, which are used to prevent pregnancy in the first few days after unprotected sexual intercourse, sexual assault, or contraceptive failure. This guideline recommends increasing access to emergency contraception, including removing the age restriction for over-the-counter access.

Committee Opinion: Adolescents and Long-Acting Reversible Contraception: Implants and Intrauterine Devices

“Adolescents and Long-Acting Reversible Contraception: Implants and Intrauterine Devices,” issued by ACOG in October 2012 (reaffirmed 2016), recommends the use of IUDs and the contraceptive implant as first-line contraceptive options for sexually active adolescents.

Practice Bulletin: Noncontraceptive Uses of Hormonal Contraceptives (members only)

“Noncontraceptive Uses of Hormonal Contraceptives,” issued by ACOG in January 2010 (reaffirmed 2016), covers the use of hormonal contraceptives in treating menstrual bleeding, dysmenhorrhea, premenstrual dysphoric disorder symptoms, menstrual migraines, ovarian cysts, and acne. The guideline also reviews evidence for their effect on bone mineral density, as well as prevention of endometrial and ovarian cancers.

How I Practice Video Series: Contraception

“Contraception,” a video in the How I Practice series, issued in July 2012, features Eve Espey, MD, FACOG, who describes her clinical approach. She discusses birth control with women of child-bearing age at every opportunity and recommends effective methods, especially LARC methods.

Book of Guidelines Supplement: Reproductive Health Care for Adolescents with Disabilities (members only)

Committee Opinion: Adolescent Pregnancy, Contraception, and Sexual Activity

"Adolescent Pregnancy, Contraception, and Sexual Activity," issued by ACOG in May 2017, discusses sexuality education and contraceptive options for adolescents, including long-acting reversible contraception, condom use, and birth control pills.

Committee Opinion: Comprehensive Sexuality Education

"Comprehensive Sexuality Education," issued by ACOG in November 2016, explains the importance of medically accurate, evidence-based, and age-appropriate sexuality education, which should provide information about reproductive development, contraception (including long-acting reversible contraception methods) to prevent unintended pregnancies, and prevention of sexually transmitted infections (STIs).
