title: Acute menopausal transition associated with clomiphene therapy: Two case reports.
abstract: Two patients presenting with anovulation and secondary infertility were treated with clomiphene citrate. Intermittent blood samples were obtained for the first three months of therapy in each case. One patient failed either to ovulate or menstruate in response to clomiphene and the other patient had only two episodes of cyclical bleeding before she too became amenorrhoeic. Hormonal analyses revealed that both women had undergone a rapid and precocious menopausal transition which has persisted throughout the subsequent three years.
