Equality for the sexes?
Article Abstract:
Results from a study of male contraception carried out by the World Health Organization (WHO) showed that a new agent was highly effective. Only one pregnancy occurred in the partners of 119 subjects who had apparently complete suppression of sperm production during the 12-month study period. In addition, this single pregnancy may have been the result of fertilization from another source. The method use in the study was a weekly injection of the male hormone testosterone enanthate, which produced acne and increased aggressiveness in some men (who withdrew from the study), but had no apparent serious side effects. The next phase of the study will concentrate on men with reduced sperm production as a result of the drug, whose remaining sperm may not be functional. Sperm production was completely prevented in only 65 percent of the men in the first study. Another goal of WHO is to develop a different way of administering testosterone, since the present regimen of weekly injections is not likely to be popular. Possibilities include a thrice-yearly injectable form. The International Planned Parenthood Federation hopes the option will be available within five years. Not only is it preferable to condoms, but some groups who reject surgical methods such as vasectomy may accept injections. WHO is also developing a reversible vasectomy procedure, which is under evaluation in China. An actual 'contraceptive vaccine' for men, however, does not seem likely in the near future.
