[Unexplained sterility. Treatment with superovulation and intrauterine insemination]

Fifty couples with unexplainable sterility, were selected for study. They were treated following a uniform treatment protocol, consisting in inducin superovulation by human menopausic gonadotropins hormones, followed by intrauterine insemination with husband's fresh semen. One hundred and thirty six cycles of treatment, were obtained; 15 pregnancies were achieved, corresponding to 30% of the total of couples, and to 11% of amount of treatment cycles. These figures were similar to other author's, and similar to the ones obtained by intrauterine gametes transference. It is concluded that this a new alternative of treatment that may be used before IGT, or in places where there is not such methodology.
