Title: Serum luteinizing hormone during ovulation induction with human menopausal gonadotropin for in vitro fertilization in normally menstruating women
Abstract: Sixteen cycles in 14 normally menstruating women, stimulated with human menopausal gonadotropin in order to recruit more than one follicle for a successful in vitro fertilization process, were adequately monitored to identify the appearance of the spontaneous luteinizing hormone (LH) surge. Daily serum LH determinations, increased to every 4 hours in the presumptive preovulatory period, showed that in these women the endogenous estrogen-triggered LH midcycle peak did not occur at the expected time. It is hypothesized that the mechanism responsible for this suppression is a negative feedback mediated by an increased circulating protein with an inhibin-like action.
