Clomiphene citrate therapy for male infertility.
We have summarized 697 reported cases of the use of clomiphene citrate for the improvement of semen quality. Basal levels of gonadotropins are useful criteria for the differential diagnosis of hypo- and hypergonadotropic hypogonadism. Patients with an intact hypothalamic-pituitary-gonadal axis are most likely to respond to clomiphene citrate. Twenty-five mg. per day, administered in a cyclic fashion for a period of six to nine months, caused the greatest improvement. A higher dose (50 mg. per day) may be effective in men who do not respond to 25 mg. During the course of therapy gonadotropin levels and semen samples should be analyzed periodically. This drug is not currently approved for use in men; the incidence of side effects, particularly with long-term treatment, is unknown.
