title: The efficacy of every-other-day administration of gonadotropin-releasing hormone in women with hypothalamic amenorrhea: gonadotropin-releasing hormone treatment can induce clomiphene responsiveness.
abstract: The efficacy of every-other-day gonadotropin-releasing hormone administration was investigated in clomiphene-human chorionic gonadotropin (hCG) resistant, anovulatory women with hypogonadotropism or normogonadotropism. One hundred micrograms of gonadotropin-releasing hormone was injected intramuscularly three times a week for four weeks (one course). Ten of 11 hypogonadotropic patients responded to clomiphene or clomiphene-hCG after one to three courses of gonadotropin-releasing hormone treatment. Once the patients were converted to clomiphene responsiveness, ovulatory response continued without additional treatment, and all four patients who desired pregnancy conceived. Among eight normogonadotropic women, four with amenorrhea of one year or less became clomiphene-hCG responders after one or two courses of gonadotropin-releasing hormone treatment. They were subsequently treated with gonadotropin-releasing hormone after every one or two ovulatory cycles. One of the four women who desired to be pregnant conceived. We conclude that intramuscular gonadotropin-releasing hormone treatment is effective in inducing responsiveness to clomiphene, especially in hypogonadotropic anovulatory women. In normogonadotropic women, gonadotropin-releasing hormone treatment may be useful in those who have been amenorrheic for less than a year.
