THE ROLE OF GONADOTROPINS IN OVULATION INDUCTION

Currently two types of gonadotropin preparations are commercially available for ovulation induction: menotropins and follicle-stimulating hormone (FSH). Proper use of these agents is directed by many factors. Concern about the FSH-luteinizing hormone ratio and the bioconsistency of the preparations suggests the use of FSH in most situations. Regimens based on short-term incremental increases in gonadotropin dose (based on frequent sonographic and biochemical monitoring) seem to produce the highest pregnancy rates. Individualization of the patient's ovulation induction course on the basis of history of medication use and the reasons for ovulation induction therapy are also essential to optimize outcomes.
