Ten women ages 22 to 39 years were treated with a single injection of Delestrogen on day 19 of the menstrual cycle and increasing doses of Parlodel on days 19 to 23. This treatment resulted in a shortening of the luteal phase and a decrease in the production of progesterone and had no effect on serum luteinizing hormone (LH), follicle-stimulating hormone (FSH), or prolactin levels. Side effects reported with this therapy included lethargy, dizziness, nausea, vomiting, hot flashes, depression, and nasal congestion. These preliminary clinical data suggest a combination of estrogen and bromocriptine regimen is luteolytic and may be useful as an interceptive abortifacient preparation in the human being.

In the 1974-86 period, gossypol acetate was taken as an antifertility measure by 16 men. The initial dose was 20 mg/day, with a maintenance dose of 40 mg/week. Antifertility efficacy was obtained in all 16 cases. Azoospermia persisted in 1 case where the gossypol had been taken for 8 years and discontinued for the past 2 1/2 years. Symptoms experienced in the first 2 weeks of gossypol acetate administration included dizziness, anorexia, nausea, fatigue, and stomach discomfort. Results of examinations of blood and urine; functions of the heart, liver, lung, and liver; electrolytes; external genitalia; and sexual performance were all in the normal range. Measurements of semen, plasma biochemistry, and endocrine changes also were within normal limits. However, in the 9 cases in which the average value of plasma testosterone was near the lower limit of normal, the average value of follicle-stimulating hormone was higher than normal and the testosterone/luteinizing hormone ratio was unusually low. Testis biopsy indicated that long-term gossypol treatment affected both germ cells and Sertoli cells. Leydig cells also demonstrated some damage. Gossypol acetate is, in general, considered an ideal male contraceptive because of its long-term effectiveness, reversibility, and lack of severe toxic side effects.

Depot medroxyprogesterone acetate (DMPA, Depo-Provera) is used for contraception by 8-9 million women in more than 90 countries, including the US, as of January 1993. Pharmacologically active levels of DMPA persist for 3-4 months following injection. A 150 mg dose is used most often for high contraceptive efficacy every 3 months. Norethindrone enanthate (NET-EN, Noristerat) is somewhat less widely used and is not marketed in the US. Injectables act primarily by inhibiting ovulation, lowering the levels of follicle-stimulating hormone and luteinizing hormone. Approximately 50% of women using DMPA for 1 year report amenorrhea whose occurrence is less frequent with NET-EN. Menstrual changes are the most frequent causes of discontinuation of injectables. In cases of heavy bleeding it is appropriate to undergo gynecological examination to rule out unrelated conditions, such as vaginitis, cervicitis, or cervical lesions. The use of conjugated estrogen (12.5-2.5 mg daily) for 10-21 days will minimize bleeding. Some women using injectables experience headache, dizziness, bloating of the abdomen or breast, and mood changes. Long-term use of DMPA or NET-EN can often result in 1-3 kg weight gain. The WHO Collaborative Study of Neoplasia and Steroid Contraceptives was launched in 1979 to examine cancer risks with the use of DMPA in Thailand, Mexico, and Kenya. The relative risk of breast cancer was 1.21, which was statistically not significant. In women diagnosed with breast cancer under age 35, short-term exposure to DMPA was associated with a slightly increased breast cancer risk, which, however, was not associated with duration of use. DMPA dramatically lowers the risk of endometrial cancer for at least eight years following discontinuation of its use. DMPA did not alter the risk of cervical cancer. Fertility returns in 70% of former users within 12 months; it is suitable for postpartum and lactating women, and provides other noncontraceptive benefits.
