Multicenter Study Comparative Study Clinical Trial Controlled Clinical Trial
Patient acceptability and satisfaction with Lunelle monthly contraceptive injection (medroxyprogesterone acetate and estradiol cypionate injectable suspension).
The results from a User Satisfaction Questionnaire, Treatment Assessment Questionnaire, and Global Well-Being Schedule questionnaire administered to women participating in an open-labeled, nonrandomized, parallel, controlled study comparing a new monthly injectable contraceptive containing 25 mg of medroxyprogesterone acetate (MPA) and 5 mg of estradiol cypionate (E2C) (MPA/E2C) (Lunelle Monthly Contraceptive Injection) and a triphasic norethindrone (0.5, 0.75, 1.0 mg)/0.035 mg ethinyl estradiol (NET/EE) oral contraceptive (Ortho-Novum 7/7/7) are reviewed. Approximately 85% of all 1103 women enrolled in the comparative trial completed their initial and final questionnaires. To better assess the comparison of a new and extant method of contraception, outcome data were divided among MPA/E2C users and new and previous oral contraceptive (OC) users. ⋯ In general, MPA/E2C was well accepted by women in the study group. Their attitudes and perceptions are similar to those of women who were starting OCs for the first time. These data support the premise that MPA/E2C may become a well accepted, first-line contraceptive option for women in the US.

A case of uterine perforation which occurred two months after the insertion of a Gynefix, a frameless filiform copper intrauterine device fixed into the fundal myometrium is described. Laparoscopic removal of the device had to be performed. The incidence of this complication is unknown. The appropriateness or need of assessing echo-graphically the myometrial thickness before the insertion and of controlling its correct position after the insertion remains uncertain.

The "pop-out" technique is a method of levonorgestrel implant removal that uses digital pressure to direct implants through a small skin incision. This technique was developed, theoretically, to cause less bruising and patient discomfort by avoiding the use of instruments. The pop-out technique is the primary method used for levonorgestrel implant removal in the Magee-Womens Hospital resident clinic. ⋯ Only 0.7% (7/1,008) of levonorgestrel implants were fragmented during removal. This review shows that the "pop-out" method is a reasonable alternative to other proposed methods of primary implant removal. The difference in the level of expertise of the attending physician may significantly influence removal time when training clinicians in levonorgestrel implant removal.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
A comparative study of two contraceptive vaginal rings releasing norethindrone acetate and differing doses of ethinyl estradiol.
Two combined contraceptive vaginal rings (CVR) each releasing approximately 1 mg norethindrone acetate (NET-Ac) and either 20 micrograms or 15 micrograms ethinyl estradiol over 24 h were tested at three clinic sites in Los Angeles, San Francisco, and Sydney. A total of 61 women were enrolled to use the ring on a schedule of 3 weeks in/1 week out for four treatment cycles. Serum estradiol, progesterone, norethindrone (NET), and ethinyl estradiol (EE) levels were assayed twice weekly in all four treatment cycles. ⋯ Side effects were infrequent and similar to those reported with other steroidal contraceptive methods. Three women complained of vaginal discharge, one with accompanying itch and one with a vaginal Candida infection in cycle 1. Overall, both of these EE/NET-Ac rings performed well, with only minor and mainly nonsignificant differences in effect on serum EE, NET, E2, and progesterone levels and lipids, and on vaginal bleeding patterns.

Multicenter Study
Efficacy, bleeding patterns, and side effects of a 1-year contraceptive vaginal ring.
A combined contraceptive vaginal ring designed to last 12 months was tested at three clinic sites. This ring released approximately 1 mg of norethindrone acetate (NET-Ac) and 20 micrograms of ethinyl estradiol (EE) daily. A total of 60 women were enrolled to use the ring in a schedule of 3 weeks in/1 week out. ⋯ All changes remained within normal limits and were similar to those seen with many oral contraceptives. It appears that this ring may perform slightly differently in different populations, but is a highly satisfactory method of contraception for many women. Minor modifications in design could provide higher levels of steroid release and in the later months of the ring life span would assure continuing high levels of contraceptive protection for heavier women.
