title: Initial experiences with subcutaneous pulsatile human menopausal gonadotropin administration: successful induction of ovulation in patients with polycystic ovarian disease.
abstract: Human menopausal gonadotropin (hMG) was administered to 10 patients with polycystic ovarian disease (PCOD) who had failed to ovulate in response to clomiphene citrate. Five patients (group 1) were treated with intramuscular hMG injections daily, on an individually adjusted regimen. Five others (group 2) were stimulated with subcutaneous hMG in a pulsatile fashion by means of a portable infusion minipump. The pulse doses ranged between 3.5 and 7.7 IU FSH per pulse at a constant frequency of 90 minutes. Sixteen of 18 treatment cycles were ovulatory, 9 under intramuscular, and 7 under subcutaneous treatment. A total of two patients conceived with singleton pregnancies, one in each treatment group. Neither ovarian hyperstimulation nor complications of injections were noted. The amount of subcutaneous hMG required to achieve ovulation was significantly less (46.5%; P less than .001) than that needed with intramuscular administration. However, there were no differences in the duration of stimulation periods, the lengths of luteal phases, or serum E2 and gonadotropin levels between the groups. In conclusion, pulsatile subcutaneous hMG administration may be an alternative delivery mode for patients with PCOD.
