Hormonal contraception. ACOG Technical bulletin. Number 198-October 1994 (replaces No. 106, July 1987) American College of Obstetricians and Gynecologists.

Oral, injectable, and implantable contraceptives offer women safe, effective, and reversible fertility regulation. In some cases, their use also confers important noncontraceptive benefits. By individualizing counseling and recommendations based on relevant behavioral and medical considerations, clinicians can maximize their patients' success with hormonal contraceptives. Even in women with relative contraindications to the use of hormonal contraceptives, the risks associated with pregnancy may be sufficiently great so as to warrant their use.
