Timing of onset of contraceptive effectiveness in Norplant implant users. II. Effect on the ovarian function in the first cycle of use.

The objective of this study was to time the onset of contraceptive effectiveness in Norplant implant users, when the capsules were inserted beyond the first 7 days of the cycle, based on the immediate effect on the ovarian activity. A total of 42 healthy women requesting Norplant implant contraception were enrolled at clinics in Santo Domingo, Dominican Republic, and in Baltimore, Maryland. Implants were inserted on days 8-13 of the menstrual cycle.

Timing of onset of contraceptive effectiveness in Depo-Provera users. II. Effects on ovarian function.

Objective: To determine the timing of onset of contraceptive effectiveness after the first injection of 150 mg of depot medroxyprogesterone acetate (DMPA) administered between days 8 and 13 of the menstrual cycle.

Design: Descriptive, prospective study.

Setting: A tertiary university referral center.

Timing of onset of contraceptive effectiveness in Norplant implant users. Part I. Changes in cervical mucus.

Objective: To provide scientific data regarding the changes in cervical mucus within the first hours to days after Norplant implant insertion and to estimate when the cervical mucus is hostile enough to suggest a contraceptive effect.

Design: Multicenter, clinical descriptive study.

Setting: Family planning clinics.

Timing of onset of contraceptive effectiveness in Depo-Provera users: Part I. Changes in cervical mucus.

Objective: To evaluate the changes in cervical mucus within the first hours or days after depot medroxyprogesterone acetate (MPA) injection so as to estimate the time at which cervical mucus becomes hostile enough to prevent pregnancy.

Design: Multicenter, clinical descriptive study.

Setting: Family planning clinic.

Treatment of bleeding problems associated with progestin-only contraceptives: survey results.

Simple, well-documented, effective and inexpensive management approaches are needed for the short-term control of bleeding in progestin-only contraceptive (POC) users. Long-term continuation may improve if acceptable approaches are found to ameliorate these short-term bleeding problems. Family planning providers and researchers were surveyed on the treatment regimens they used for POC-associated bleeding disturbances.
