[Hypophyseal reaction state during oral contraceptiva (author's transl)].

In 5 normocyclic women, firstly taking a conventional oral contraceptive, Neogynon (50 mcg EE + 250 mcg levo-norgestrel) for 6 months, the levels of LH, 17 beta-E2 and progesterone did not rise after changeover to a dose-reduced pill, Microgynon 30 (30 mcg EE + 150 mcg levo-norgestrel). This fact indicates maintained central suppression. Examination of the hypothalamic-hypophyseal axis by the Gn-RH test (50 mcg) with Microgynon 30 showed negative results during the first treatment cycle in 13 out of 18 women. In the 6th treatment cycle only 7 Gn-RH non-reactive women were observed and after stimulation with 100 mcg Gn-RH only 5 women remained with negative Gn-RH tests. Of the 20 women who took conventional oral contraceptives over a period of 6 months to 6 years (7 took Eugynon: 50 mcg EE + 500 mcg D,L-norgestrel, 5 Lyndiol: 75 mcg mestranol + 2.5 mg lynoestrenol, 8 Neogynon, only one from the Neogynon group showed a positive result. On the other hand there was a positive reaction in 4 out of 7 women using the two step dose-reduced preparation Sequilar (11 tablets of 50 mcg EE + 50 mct levo-norgestrel and 10 tablets of 50 mcg EE + 125 mcg levo-norgestrel).

The introduction and use of Norplant implants in Indonesia.

In this study, patterns of Norplant use in Indonesia are reviewed to assess the implications of this experience for the introduction of new contraceptive methods. Data from the Norplant Use-Dynamics Study and the 1994 Indonesia Demographic and Health Survey are analyzed, and patterns of acceptance, continuation, and removal are described. Acceptance of Norplant has increased steadily since it was first introduced. The method is now used by more than 5 percent of all married women of reproductive age. Continuation rates among Norplant users are higher than among users of the IUD. One factor behind high continuation rates may be that a substantial proportion of acceptors were not told that removal before five years was possible. Results indicate that deficits occurred in the quality of service delivery and that a need exists for improved provider training, better supervision, and clearer and better-enforced guidelines regarding women's right to have Norplant removed on demand.

Preliminary experience with Norplant in an inner city population.

Norplant, the five-year subdermal contraceptive system, is the first implantable contraceptive method approved for general use in the United States. We describe the preliminary experiences of 246 U.S. women who accepted Norplant between April, 1991 and September, 1991. Norplant was well accepted among this diverse general population. Intensive counselling about side effects, especially menstrual changes, is crucial for patient satisfaction. Although 48% of acceptors experienced menstrual cycle changes and 70% experienced at least one side effect, phone calls and unscheduled visits for problems were infrequent. Adequate counselling about side effects obviates the need for a routine follow-up visit one month after insertion.

Reproductive tract infections in a family planning population in rural Bangladesh.

In contrast to social, religious, and economic determinants of acceptance and sustained use of family planning in developing countries, perceived side effects resulting from reproductive tract infections can usually be ameliorated easily and expeditiously. This population-based study examines the magnitude and nature of morbidity due to reproductive tract infections among users of various contraceptive methods and among nonusers in a rural community in Bangladesh. Overall, 22 percent of the 2,929 women surveyed reported symptoms of reproductive tract infection. Of the 472 symptomatic women examined, 68 percent had clinical or laboratory evidence of infection. Users of intrauterine devices and tubectomy were each approximately four times as likely to report symptoms and seven times as likely to have examination-confirmed infection as nonusers. The epidemiology of reproductive tract infections in this population is addressed, and the findings are discussed in terms of their potential programmatic impact.

Protection against endometrial carcinoma by combination-product oral contraceptives.

Seventy-nine patients with endometrial carcinoma were compared with 203 control subjects regarding their use of combination-product oral contraceptives (OCs). Overall, 6.3% of patients and 15.3% of control subjects had used these products. The risk of endometrial cancer for users of OCs was less than half the risk for nonusers. Five years or more of use reduced the risk to a third. Recent users were strongly protected, whereas discontinuation resulted in risks returning to those of nonusers. Furthermore, OCs with predominantly progestational effects of intermediate formulations produced greater protection than those with predominantly estrogens. This pattern of results is biologically consistent with a protective effect of combination-product OCs against endometrial carcinoma.

Intrauterine devices and pelvic inflammatory disease.

There is convincing clinical evidence that PID is more common in IUD users than in users of other contraceptive methods. There appears to be a smaller but significant increase when IUDs are compared with sexually active noncontraceptive users. However, the incidence of PID severe enough to warrant hospitalization is only of the order of 1 to 2 per 1,000 women per year. The question which remains is whether beyond this low figure of moderate and severe disease there is a much higher incidence of subclinical PID which may result in complications for IUD users. Development of a marker such as C-Reactive protein or the split complement component C3d to detect mild PID would prove invaluable in the elucidation of several crucial problems in the clinical management of women using IUDs.

Effect of oral contraceptives on plasma androgenic steroids and their precursors.

Plasma dehydroepiandrosterone (DHEA), its sulfate ester (DHEAS), and androstenedione (A2), delta5-pregnenolone (delta5-P), and 17 alpha-hydroxypregnenolone were measured in women using estrogen-containing oral contraceptives and in female controls of similar age. All three androgenic steroids and their two C21 precursors were reduced in the oral contraceptive users compared with the controls. It is concluded that oral contraceptives cause a decrease in plasma DHEA, DHEAS, and A2, one possible mechanism for which is the inhibition of delta5-P synthesis from cholesterol.

Effects of seven low dose combined oral contraceptives on high density lipoprotein subfractions.

The effects on lipid metabolism of seven combined oral contraceptives were investigated, particularly the effects on high density lipoprotein (HDL) subfractions, which were separated by density gradient ultracentrifugation. There were no differences between the preparations in the effects on the LDL fraction, the so-called atherogenic particle, but there were marked differences in the effects on the anti-atherogenic HDL fraction, of which the effects on HDL-2 were most pronounced. After treatment with monophasic cyproterone acetate and biphasic desogestrel, the cholesterol and phospholipid contents of the HDL-2 fraction were significantly higher than those found after treatment with the other preparations. The lowest values were found after treatment with monophasic levonorgestrel, whereas monophasic desogestrel, triphasic levonorgestrel, monophasic norethisterone and triphasic gestoden induced intermediate values for these variables. The levels of HDL-2 reflect the intrinsic androgenicity of the various progestogens used in the preparations.

Continuation and compliance of contraceptive use.

Choosing a method of contraception is an important decision as regards user satisfaction, continuation of use and compliance. The issues of continuation of and compliance with contraceptive use are presented. The continuation rate of a method of contraception is the indicator of the acceptability of that method. The highest continuation rates at the end of the first year are recorded for subdermal implants, intrauterine devices (IUD), the pill and Depo-Provera. Lower continuation rates are found for periodic abstinence, male condom, female condom, diaphragm and spermicides. Continuation rates are highest for methods not affected by compliance. Compliance indicates the degree to which the patient adheres to a prescribed regimen. Lack of compliance can lead to adverse effects of contraceptive use (unintended pregnancy, side-effects, diminished non-contraceptive health benefits) and to discontinuation of the contraceptive method. Also, differences between method effectiveness and user effectiveness can largely be attributed to compliance with the prescribed contraceptive regimens. Health-care professionals have to empower the patient to increase compliance with the existing methods. In addition, the development and use of new contraceptive methods, which take into account the issues of non-compliance, should be encouraged.

IUD insertion following induced abortion.

In a multicenter survey, women who received an IUD immediately after abortion were compared with abortion patients who started using oral contraception. Additionally, women receiving a Nova T were compared with women receiving a Multiload 250. Follow-up data were gathered after 6 weeks. Pain was a common phenomenon post-abortum. In the study group of IUD users, complaints about pain were not more frequent than among controls, but if pain was experienced, it was more intense and of longer duration among IUD users. Bleeding immediately following the induced abortion was less frequent among IUD users, but if bleeding occurred, it tended to last longer. The first menstrual period after the induced abortion was heavier and more painful among IUD users. Expulsion of the IUD occurred in 10 cases (3.3%), all of them with the Nova T, none with Multiload. The study did not generate evidence for an increased risk of PID in women receiving an IUD after an induced abortion.

Contraceptive delivery in the developing world.

A strong demand for family planning exists in most developing countries and family size is falling rapidly in many of them. Effective family planning programmes offer a world-wide range of choices (including voluntary sterilisation and abortion) through a variety of distribution channels. Universal access to voluntary family planning can be achieved easily and cheaply by the turn of the century, but only if conservative medical policies are overcome and funding is greatly expanded. The international community faces a genuine choice: if it responds to current opportunities the global population will stabilize at approximately 10 billion or fewer; if it fails, population may grow to 14 billion or more. The difference between these two projections (approximately equal to the present world population of 5.4 billion) may well determine the future of the planet.

Effect of progestins on glucose and lipid metabolism.

Gestamimetic amounts of progesterone enhance basal and glucose-stimulated insulin production. Contraceptive doses of synthetic progestins cause a moderate increase or no change in glucose-stimulated insulin production, depending on route of administration and species tested. Estrogens potentiate the insulinotropic effects of progesterone and the synthetic progestins. Basal serum triglyceride concentrations are generally unaffected by progesterone or 17 alpha-acetoxyprogesterone treatment but may decrease during 19-nortestosterone administration. Glucose tolerance does not change during treatment with gestamimetic doses of progesterone alone but may improve in rats and monkeys during concurrent estrogen administration. By contrast, deterioration of glucose tolerance is observed in women treated concurrently with synthetic estrogen plus 19-nortestosterone derivatives and, occasionally, with 19-nortestosterone derivatives alone. No consistent changes in glucose metabolism have been observed after treatment with 17 alpha-acetoxyprogesterone derivatives alone. The cause of the species-related differences in glucose metabolism during 19-nortestosterone treatment is obscure.

A low-dose triphasic oral contraceptive.

Controlled clinical investigations of a three-phase, low-dose oral contraceptive combination of levonorgestrel and ethinyl estradiol were conducted at 17 sites in the United States and 60 sites in the United Kingdom. A day 1 start in cycle one with no backup contraception was used. A total of 3546 female volunteers participated in 35,036 cycles. Medication was missed in 2688 (7.7%) cycles. Nine pregnancies were reported for an uncorrected use-effectiveness rate of 0.33 per 100 woman-years. Cycle control was excellent, bleeding irregularities were minimal, and the incidence of side effects was very low. No clinically significant variations in blood pressure means or weight means were observed. Carbohydrate and lipid metabolism studies were limited to 6 months and showed minimal alterations. Subject compliance with the preparation was excellent. It is concluded that this triphasic oral contraceptive with its varying ratios of levonorgestrel and ethinyl estradiol is an effective, predictable, and well-tolerated combination oral contraceptive.

Japan, Indonesia to investigate condom plant feasibility.

The Japanese government has begun investigations on the possibility of constructing a condom manufacturing plant in Indonesia in response to a request by the Indonesian government. Indonesia, which hopes to reduce its birthrate as of 1971 by 1/2 by 1990, asked for Japanese assistance in building a condom plant based on the expectation that demand for this contraceptive method, although quite low at present, will increase rapidly in the near future with stepped-up motivation campaigns. As a 1st step in the investigation, the Japan International Cooperation Agency (JICA) sent a study team of family planning experts headed by Family Planning Federation of Japan Chairman Dr. Hidebumi Kubo and including JOICFP International Division Director MR. Tameyoshi Katagiri to Indonesia from March 15-24. During its visit, the JICA team held discussions with representatives of BKKBN (the National Family Planning Coordinating Board) including its Chairman and Minister of Health Dr. Suwardjono and reached agreement on the scope and schedule of work toward determining the feasibility of building and operating a condom plant in Indonesia. In defining the scope of work and the schedule, the JICA team and the BKKBN representatives decided on specific issues to be investigated in the feasibility study to be carried out by JICA and scheduled to be completed by the end of October of this year. To be included in the feasibility study are: estimation of future domestic demand for condoms, examination of the domestic supply of latex capacity, chemicals and packaging materials, and collection of information on infrastructure relating to water, energy, transportation, etc. Actual data collection for the study is expected to begin in late May or early June. Dr. Kubo and Mr. Katagiri, upon returning to Japan, reported great enthusiasm for the project in Indonesia and expressed the hope that the plant construction will be feasible so that the country's family planning program can be given a boost and the cooperative relationship between Indonesia and Japan deepened.

Attenuation of mild hyperandrogenic activity in postpubertal acne by a triphasic oral contraceptive containing low doses of ethynyl estradiol and d,l-norgestrel.

The effect of a low dose triphasic oral contraceptive (OC) was evaluated during a 6-month treatment period in 41 patients (mean age, 25.4 +/- 0.7 yr) who had grade I-IV postpubertal acne and normal menses. The OC contained three dose levels of ethynyl estradiol and dl-norgestrel. Acne lesions were assessed, and serum androgen levels were measured during a control cycle and between days 17-21 of treatment cycles 1, 2, 3, and 6. Four patients dropped out after 3 months of treatment. Acne was significantly improved after the first OC cycle. After six cycles, the number of comedones had decreased by 79.6 +/- 3.2% (range, 50-100%) in 69.4% of the patients. Mean baseline levels of testosterone, 17-hydroxyprogesterone, and dehydroepiandrosterone sulfate were in the upper third of the normal range, with elevated individual values in 18.9%, 36.5%, and 26.8% of the women, respectively. Mean baseline levels of androstenedione, free testosterone (T), and 3 alpha-androstanediol glucuronide (3 alpha-diol-G) were above the normal range, with elevated individual values in 51.2%, 75.0%, and 85.4% of the patients, respectively. Sex hormone-binding globulin (SHBG) levels were below the normal range in 26.8% of the cases. At the end of the first OC cycle, there was a significant (P less than 0.01) decrease in all androgen precursors and a 2-fold increase in SHBG. Androstenedione and free T decreased into the normal range during OC intake. Serum 3 alpha-diol-G levels remained elevated, but had decreased by 34.5% at cycle 6 (P less than 0.05). These results show that the triphasic OC has significantly improved acne in postpubertal women for whom acne was the main manifestation of mild hyperandrogenic activity. The improvement in acne corresponded to a decrease in adrenal/ovarian androgens and free T, which led to a decreased metabolism to 3 alpha-diol-G, presumably by the sebaceous glands. The increase in SHBG is considered an estrogenic effect, and the triphasic formulation containing low dose dl-norgestrel is not androgenic but, rather, an estrogen-dominant formulation; as such, this product is recommended in women requiring contraception who also have idiopathic acne.
