The use of gonadotropins for induction of ovulation.

There has been impressive progress in the treatment of anovulation with gonadotropins in the last two decades. At the present time most patients can be helped. The treatment is expensive and complicated. To obtain good results with the fewest complications, patients should be closely monitored by measuring urinary or plasma estrogen levels, and treatment should be given only in centers where the estrogen assay is readily available. Severe hyperstimulation is avoidable, but the high rate of multiple gestations remains unavoidable. Possibly with sonographic monitoring of follicular development this problem will be solved.
