Clomiphene-dexamethasone treatment of clomiphene-resistant women with and without the polycystic ovary syndrome

Abstract

We used clomiphene and dexamethasone in 40 infertile women to treat chronic anovulation resistant to the use of clomiphene alone. Eighteen (45%) of the women had the polycystic ovary (PCO) syndrome; the remaining 22 (55%) had clomiphene-resistant anovulation from idiopathic causes. Both groups of women were similar in regard to age, parity, duration of infertility and absence of other causes of infertility besides chronic anovulation. Ovulation could be induced in approximately 90% of the women in each group. Altogether, 19 of 36 women (52.8%) conceived without any side effects or complications. The cumulative probability of conception at nine months of treatment was 87.5% in PCO patients and 46% in the non-PCO group. Clomiphene plus dexamethasone was highly effective in the treatment of clomiphene-resistant anovulation associated with infertility in women with and without the PCO syndrome.
