Hormonal male contraception: progress and prospects for the 21st century.

During the second half of the 20th century, progress in developing novel, practical contraceptive methods for men has lagged significantly behind developments for women. Despite the lack of reliable, reversible methods, men throughout the world continue to be strongly involved in family planning but a greater involvement will require more attractive and reliable contraceptive options for men. The closest to fruition are hormonal methods the features of which are reviewed. Landmark WHO contraceptive efficacy studies have established that hormonally-induced azoospermia provides highly effective and reversible contraception for at least 12 months with minimal short-term side effects. Even among the small subgroup of men who remain oligozoospermic during hormonal suppression, good contraceptive efficacy is achieved. The present goals are to develop improved second generation hormonal regimens which provide more uniform azoospermia to obviate the need for monitoring of sperm output and to develop long-acting depot testosterone formulations used alone or with additional gonadotrophin suppressive agents such as progestins or GnRH antagonists. Significant obstacles to progress are the flight of industry from contraceptive R&D dur to the financial deterrent posed by the product liability crisis as well as the low priority accorded male reproductive health. Together those will determine whether the range of contraceptive options available to our children in the 21st century will improve, or whether the historically recent unbalanced increase in reliance on women for family planning will continue.

A study of knowledge and attitudes towards contraception among health care staff in Kelantan (Malaysia).

OBJECTIVE: To study the knowledge, attitudes and practices on various contraceptive methods among all government health clinic staff in the state of Kelantan. DESIGN: Questionnaire-based study. SETTING: All government health clinics in the state of Kelantan which are health facilities located outside the general hospital and seven district hospitals. SUBJECTS: All 711 nursing staff employed in government health clinics in Kelantan state (sisters, staff nurses, assistant nurses and midwives). METHOD: Pretested, prestructured proforma was sent out to all the nursing staff employed in all peripheral health centres to be completed by them and returned the same day via the medical officer in charge of that district. RESULTS: Most of the respondents were more than 30 years of age, married, multiparous and working for more than 5 years. Eighty to ninety percent practised contraception, with the majority of midwives preferring pills and the majority of staff nurses preferring condoms. Thirty to forty percent from all groups felt that folk methods are effective, and should be encouraged. Only about 50% of staff nurses are well informed on all contraceptive methods, but among assistant nurses and midwives, this figure is only 33%. A high proportion felt that the nursing curriculum deals inadequately with this subject. CONCLUSION: The first step towards achieving success in our family planning programme lies in imparting more information to this target group of health workers, by incorporating more lectures during training and sending them for courses.

The effects of desogestrel and ethinylestradiol combination in normal and hyperandrogenic young girls: speculations on contraception in adolescence.

Hormone profile and ovarian morphology were studied in two groups of adolescents (group 1:19 girls with slight signs of hyperandrogenism; group 2: 14 normal adolescents) in basal conditions and during a contraceptive combination of 30 micrograms ethinyl estradiol (EE) and 150 micrograms desogestrel (D). Treatment was associated with a low incidence of side effects in both groups. In group 1, acne generally improved within 12 months while hirsutism was only reduced in some subjects (58%) after 12 months of therapy (basal hair score 8.50 +/- 1.60 vs 5.81 +/- 1.53 p less than 0.001). Significant falls in plasma levels of LH, total and free testosterone and an increase in sex-hormone-binding globulin levels were observed during treatment especially in group 1. High percentage of multifollicular ovaries (75%) characterized hyperandrogenic subjects. Ovarian volume and number of follicles, higher in group 1 than 2 in basal conditions, showed a significant reduction in both groups and normal ovarian morphology was restored in hyperandrogenic subjects. Considering the high incidence of hyperandrogenemia in adolescence and its implications, our data suggest that the EE.D combination suits adolescent biological condition and is one of the suitable contraceptive methods in adolescents which also has therapeutic effects.

Contraception survey: Denmark 1988.

In 1988 a survey** was conducted in 1,033 women living in Denmark, whose ages ranged from 15 to 44 years. The main aims of the study were to identify the influence, if any, of demographic and socioeconomic factors on contraceptive use and to assess the women's knowledge of selected facts concerning their own fertility. The study's additional objectives were to gain insight into factors influencing communication on the subject of contraception, such as advice obtained from professional counsellors, general information dissemination and discussion between partners, and to investigate women's attitudes and opinions regarding contraceptive methods and their use. The results are discussed in relation to the findings of other studies on the use of contraceptives both worldwide and in a number of European countries. The Danish findings are also examined in the context of possible action to reduce the relatively high rate of legally induced abortions in Denmark.

The effect of user fees on the utilization of family planning services. A clinical study.

A new fee structure was introduced to the Advanced Training and Research in Fertility Management Unit in 1992. The study looked at the effect of the new fees on attendance and the choice of contraceptive methods through an examination of clinical records and a questionnaire survey. There was a decline in attendance of roughly 28 per cent between 1992 and 1993. The decline affected mainly new clients and those who accepted injectables. A reduction in the price of injectables is suggested since the fee for this short-term method is more in line with those charged for long-term and permanent methods.

Vaginal rings for contraception in lactating women.

Contraceptive methods for breastfeeding women should be safe for the mother and infant and should not interfere with lactation. Progestin-only methods meet these conditions and can be used from the sixth week postpartum. Because all progestins are excreted in milk, those that are insufficiently active by the oral route are preferable to avoid any possible effect on the baby. These steroids, however, must be administered to the mother by a non-oral route. Initially, progesterone was administered subdermally to test this concept. Subsequently, a progesterone vaginal ring was developed to be used continuously for 3 to 4 months and replaced with a new device, as needed, until weaning. Clinical trials have shown a high contraceptive efficacy (over 98.5%) and safety. The gross continuation rate of this method is approximately 40% at 12 months of use, with use-related problems being the main reason for discontinuation (26.8%). Currently, a Nestorone vaginal ring is under development, delivering 50 microg of Nestorone per day. It may be used continuously for up to one year, even if weaning occurs earlier. Both of these progestin-only rings prolong lactational amenorrhea to 10 to 12 months, which represents a health benefit and convenience for many women. The registration of the progesterone vaginal ring, developed as a contraceptive method to be used exclusively during lactation, has been approved in Chile and Perú. The fact that it is a user-controlled long-term contraceptive that delivers a natural hormone makes it an attractive option for many women.

Natural family planning effectiveness in Belgium.

The aim of the study was to check, in a European environment, the practical efficiency and the acceptability of a recent natural family planning (NFP) method. This method includes a double check to detect the beginning as well as the end of the fertile phase of the menstrual cycle. Up to now, 71 women of reproductive age have been registered. They agreed to provide their symptothermal charts and related information. Average age is 32 years. Average fertility is 2 children/woman. Fifty-nine percent of the participants have a professional occupation. The same percentages are found in those accepting a contraceptive method (oral contraceptives or intrauterine devices). Until today 1240 cycles (103 women-years) of experience have been gathered. The average participation was 17.5 cycles/woman. No method failure has been reported. One unintended pregnancy due to unprotected sexual intercourse during the fertile phase occurred (user failure). Overall Pearl Index (PI) was 0.96. In 84% of the cycles, no protected intercourse was reported (NFP only). According to PI, practical efficiency of the NFP method analyzed was 1.31. Sexual abstinence during the fertile phase was found in 71.4% of the cycles.

Contraception in women with IDDM. An epidemiological study.

OBJECTIVE: To study whether suitable contraceptive methods to women with diabetes mellitus in fact are applied. RESEARCH DESIGN AND METHODS: A questionnaire survey on the use of contraceptives in all 18-to-49-yr-old women (n = 261) with IDDM in Funen County, Denmark, and an age-comparable control group, (n = 287) was performed. Data were collected from 1987 to 1990. Response was achieved from 94% diabetic women and 88% control subjects. RESULTS: The overall use of contraception in diabetic women (77.1%) was almost identical to that of control subjects (73.6%). Compared with control subjects, significantly fewer diabetic women were using the OCP (P < 0.005) and partner sterilization (P < 0.05), whereas more diabetic women were sterilized (P < 0.0005). Among diabetic contraceptive users, the IUD, female sterilization, condoms, and the OCP each accounted for roughly 20%. Diabetic women using the OCP were predominantly young, and most had never been pregnant; approximately 20% of them used high-dose formulations. Sterilization was frequently used by older diabetic women, and most of these women had 2 or more children; 27% of the diabetic women using an IUD were nulligravidae. Further, 18% used a method with an unsuitable high failure rate. CONCLUSIONS: Our study demonstrates that diabetic women are not sufficiently advised concerning use of contraception.

The church, the state and women's bodies in the context of religious fundamentalism in the Philippines.

After almost 500 years of Spanish colonial rule, Canon law and laws of Spanish origin continue to dominate Philippine family, civil and penal law. Most if not all of these laws place serious limitations on the realisation of women's sexual and reproductive rights. Since 2002, the current president, Gloria Mocapagal Arroyo, has increasingly substituted church dogma for state policy, i.e. revoking the reproductive health and family planning policies of her predecessor, rejecting all modern contraceptive methods as forms of abortion, limiting government support for family planning to providing natural methods to married couples, and restricting access to emergency contraception. This article reflects on which advocacy methods will best serve the goals of sexual and reproductive rights when conservative church interests dominate state policy, as is currently the case in the Philippines. Religious fundamentalists, at one and the some time, argue for religious accommodation of their views by the state on the grounds of religious freedom but refuse to entertain, let alone accommodate, a plurality of views on women's sexuality. Thus, it is not enough to base a case in support of sexual and reproductive rights on the separation of church and state since, even though the State claims it is secular, it still manages to impose restrictions and control over women's bodies.

Barriers to modern contraceptive use in rural Peru.

This paper examines Quechua-speaking Indians' choice of contraceptive methods and discusses barriers to the use of modern contraceptives. A study conducted in a Peruvian highland community shows that contraceptive choice is strongly related to a couple's life experiences, their contact with urban centers, their economic status, and their emphasis on cultural values. Among contraceptive users, husbands are concerned with family size and encourage their wives to seek information about the use of modern contraceptives. A discrepancy in attitudes exists between spouses: the men's positive attitude toward modern contraception contrasts with the women's traditional desire for a large family. In this study population, modern contraception is a novelty that has reached only a few families. The majority of the couples practice natural and traditional family planning methods, which are not reliable. Villagers do not use modern contraceptives as a result of cultural barriers created by family planning services that do not take into account the lifestyle of these people, insufficient knowledge of human physiology, comments from dissatisfied users, and women's reliance on their reproductive role for self-esteem.

Estimating the efficacy of medical abortion.

Comparisons of the efficacy of different regimens of medical abortion are difficult because of the widely varying protocols (even for testing identical regimens), divergent definitions of success and failure, and lack of a standard method of analysis. In this article we review the current efficacy literature on medical abortion, highlighting some of the most important differences in the way that efficacy has been analyzed. We then propose a standard conceptual approach and the accompanying statistical methods for analyzing clinical trials of medical abortion and to explain how clinical investigators can implement this approach. Our review reveals that research on the efficacy of medical abortion has closely followed the conceptual model used for analysis of surgical abortion. The problem, however, is that, whereas surgical abortion is a discrete event occurring in the space of a few minutes or less, medical abortion is a process typically lasting from several days to several weeks. In this process, two events may occur that are not possible with surgical abortion. First, the woman can opt out of the process before a fair determination of efficacy can be made. Second, the process of medical abortion allows time for surgical interventions that may be convenient for the clinician but not strictly necessary from a medical perspective. Another difference from surgical abortions is that, for medical abortions, different medical abortion protocols specify different waiting periods, giving the drugs less time to work in some studies than in others before a determination of efficacy is made. We argue that, when analyzing efficacy of medical abortion, researchers should abandon their close reliance on the analogy to surgical abortion. In fact, medical abortion is more appropriately analyzed by life table procedures developed for the study of another fertility regulation technology; contraception. As with medical abortion, a woman initiating use of a contraceptive method can change her mind after some period of exposure and opt out. Also, as with medical abortion, a contraceptive can fail, usually with the risk of failure depending heavily on whether or not the woman follows the protocol for that method precisely. Finally, as with medical abortion, medical conditions may arise that necessitate discontinuing use of the contraceptive method. In both cases, these medical conditions are sometimes open to interpretation or subject to the skill, judgment, or experience of the clinician involved. The appropriate information to collect for a multiple decrement life table analysis of medical abortion includes data on compliance with the protocol, timing of the event of interest (abortion) when it is observable, and, because we argue that these should be regarded as events of interest, a typology of any surgical interventions that are conducted during the woman's participation in the study.

The comparative trial of TCu 380A IUD and progesterone-releasing vaginal ring used by lactating women.

The objective of this paper was to compare the efficacy, acceptability, safety, and bleeding pattern of TCu 380A intrauterine device (IUD) and progesterone-releasing vaginal ring used by breastfeeding women. The study population included 97 breastfeeding women using IUD and 100 women using vaginal ring. Of the IUD users, no insertion failure, perforation, or accidental pregnancy occurred in 12 months. There was one IUD expulsion. There were no discontinuations of IUD due to medical reasons other than expulsion. The total discontinuation rate was 2.3%. In the ring group, no accidental pregnancy occurred. The major reasons for discontinuation were ring use-related problems and vaginal problems. The total discontinuation rate was 65.4% within 1 year. The frequency of any one complaint among the ring users was higher than that among the IUD users. There were no differences in the proportion of women having no sexual activity and in the weight of their babies between the two groups. Compared with the IUD users, the median number of bleeding/spotting (B/S) episodes and B/S days of the vaginal ring users were fewer; consequently, the mean length of B/S-free interval was longer in all four reference periods; the mean length of B/S episode and segment were the same; the occurrence of amenorrhea was more frequent; in contrast, the proportions of normal bleeding patterns were fewer. The frequencies of prolonged bleeding, frequent bleeding, and infrequent bleeding patterns did not differ between the two groups. The percentage of irregular bleeding was fewer only in the first two reference periods. It is concluded that the TCu 380A IUD and progesterone-releasing vaginal ring used by breastfeeding women are safe and effective. The higher discontinuation rate of the ring users was mainly because of use-related problems. Breastfeeding women with TCu 380A IUD had better tolerance and acceptability. The TCu 380A IUD does not, but the progesterone-releasing vaginal ring does, suppress the recovery of ovarian function. However, once return of menstruation occurred, there were no differences in bleeding patterns between the two contraceptive methods.

Return of fertility in various types of IUD users.

The assessment of reversibility of a contraceptive method is of importance to both providers and users. Ninety-one women who discontinued IUD use because of desire of pregnancy were followed up for pregnancy and its outcome. Cumulative pregnancy rates at 3, 6, 12, and 18 months after IUD removal were 61.5%, 87.9%, 92.3%, and 96.7%, respectively. Mean interval from IUD removal to conception was 4.4 months (range, 1-18 months). These findings add further evidence that fertility of women is not impaired by use of IUDs as a spacing method.

Contraception and the prevention of sexually transmitted diseases.

Sexually transmitted diseases (STDs) are a major cause of ill health in women and their sexual partners and children. Contraceptive methods alter in various ways the risk of acquiring STD but assessment of the odds ratio is difficult due to the many confounding factors. Spermicides have been reported to kill a wide range of bacteria and viruses including HIV in vitro and to protect in vivo from infection by gonorrhoea, chlamydia and pelvic inflammatory disease (organisms unspecified). Spermicides will not cure pre-existing infections. Condoms and diaphragms will give some protection from bacterial and viral infections in all parts of the genital tract. Hormonal contraception and tubal ligation give protection to the upper genital tract but not the cervix. Carcinoma of the cervix follows the same pattern as STDs. The risk of pelvic infection in intrauterine device users is discussed in the chapter by Bromham (pp 100-123, this issue).

Pelvic inflammatory disease: a review with emphasis on antimicrobial therapy.

Pelvic inflammatory disease accounts for 5%-20% of hospital admissions for gynecologic problems and is associated with health care costs of more than 1 billion dollars annually. This article reviews the epidemiology, polymicrobial etiology, and diagnosis of this disease state. Special consideration is given to in vivo and in vitro studies of antimicrobial therapy, including both established regimens and expanded-spectrum beta-lactam antibiotics. The adjunctive modalities reviewed include treatment of sexual contacts, removal of intrauterine devices, use of alternative contraceptive methods associated with a reduced risk of disease, and surgery. Although understanding of pelvic inflammatory disease has increased markedly, investigation of its various aspects is both necessary and ongoing. In particular, well-designed, controlled, comparative clinical trials of new treatment regimens must be performed to verify a true advantage of these therapies.
