[Indication and effect of bromocriptine in euprolactinemic amenorrhea--comparison with clomiphene].
Effect of bromocriptine on induction of ovulation and occurrence of pregnancy was examined in patients with normoprolactinemic ovulatory disturbances. The patients under study (53 in number) were divided into two groups, A and B, depending on the effect clomiphene had on the ovulatory responses and the occurrence of pregnancy. Of the group A, patients (21 in number), who had failed to show any ovulatory response to clomiphene, 8 patients ovulated on bromocriptine alone. Three out of 13 patients who complained of sterility became pregnant. Three out of 8 patients who had not ovulated on bromocriptine therapy alone ovulated on a combination of bromocriptine and clomiphene, and 2 out of these 3 cases became pregnant. Of the group B patients (31 in number), who had failed to become pregnant in spite of ovulatory responses to previous clomiphene therapies, 7 out of 23 became pregnant, who complained of sterility when on bromocriptine alone. Out of 12 cases who had failed to get pregnant on the bromocriptine alone, 2 patients became pregnant on the combination of bromocriptine and clomiphene. These data may indicate that the bromocriptine or the combined therapy of bromocriptine and clomiphene is useful for the treatment of patients with ovulatory disturbances or sterility who do not respond to the clomiphene therapy.
