Problems in measuring the effectiveness of infertility therapy.

Couples consulting for infertility are a highly select group, and this makes the evaluation of the effectiveness of a type of therapy difficult. The most obvious selection results from the time they have been unsuccessfully waiting for a conception. Because fecundability is variable from one couple to another, the monthly probability of conceiving after 2 or 3 years of waiting time is low, but the proportion of couples who will conceive within 1 year is still significant and can be predicted. However, in most cases, couples submitted to a specific treatment include hypofertile and totally sterile couples, in unknown proportion. This fact makes difficult the measurement of the effectiveness of therapy, and procedures including control groups should be used. An example of such a process is given.

Contraceptive practices and trends in France.

CONTEXT: Contraceptive use has been legal in France for the past 30 years, and patterns of use changed substantially from the 1960s to the 1980s. Given the rapidity with which use patterns change and the possible impact of rising concern about infection with HIV and other sexually transmitted diseases, it is important to determine trends of contraceptive practice into the 1990s. METHODS: A total of 5,900 French households were selected in 1994 for inclusion in the Fertility and Family Survey. Respondents were questioned about their contraceptive use patterns and family formation status. The results were compared with those of comparable surveys conducted in 1978 and 1988. RESULTS: Two-thirds of French women used some form of reversible contraceptive method in 1994. Oral contraceptive use has grown steadily in France: About 40% of women aged 20-44 reported using the pill alone or combined with another method in 1994, compared with 34% in 1988 and 28% in 1978. Condom use has also been on the rise: Nearly 8% of women were using condoms alone or combined with another method in 1994, up from 5% in 1988 and 6% in 1978. IUD use has declined from 19% in 1988 to 16% in 1994, and both male and female sterilizations remain rare. CONCLUSIONS: Contraceptive behavior in France appears unique among developed countries, with fairly high levels of oral contraceptive use--even among older women--relatively high levels of IUD use and little reliance on either male or female sterilization. As with other countries, however, condom use has climbed in recent years, and is especially common at first intercourse.
