RESUMEN
An earlier report (1) of an adverse effect of high doses of oxytocin on human memory included results of studies on women receiving oxytocin as part of the treatment to induce 2nd trimester therapeutic abortion. These women served as their own controls. We have now been able to study a group of women who have been treated in all ways like the original group, with the exception that they did not receive oxytocin. The results from this external control corroborate the finding that oxytocin affected memory.

The authors evaluated the effectiveness of a school-based sex education program in decreasing rates of sexual intercourse, improving birth control use, and decreasing the incidence of pregnancies among teenagers 16 years of age and younger. Twenty-one schools received either the McMaster Teen Program or the conventional didactic sex education program. Preprogram, the mean age of the students was 12.6 years. There were no statistically significant differences between groups in time to first sexual activity for males, chi 2(1) = 2.93, p = 0.09; time to first sexual activity for females, chi 2(1) = 0.50, p = 0.48; and time to first pregnancy, chi 2(1) = 1.90, p = 0.17. Significantly more experimental group males reported always using birth control at year 1 (difference 8.9%; 95% confidence interval [CI] = 0.4, 17.4). Limitations of the program that may have influenced the results were the exclusion of contraception information and its short duration.

"The purpose of this study is to develop and test a multivariate, multidimensional exploratory model of successful and unsuccessful contraceptive use." The data concern 200 sexually active females who visited an obstetrics and gynecology department in Hamilton, Ontario, Canada. The authors conclude that successful contraceptive use has to be seen in a multidimensional context and is not simply a problem concerning contraceptive information. They also conclude that early sexual socialization and education, generally in the family setting, is important in the development of sexually responsible behavior.
