title: Ovulation induction with pulsatile luteinizing releasing hormone in women with clomiphene citrate-resistant polycystic ovary-like disease: clinical results.
abstract: Eighty-four treatment units were given to 11 women with clomiphene citrate-resistant polycystic ovarian disease (PCOD). PCOD was defined as oligomenorrhea elevated luteinizing hormone (LH), normal follicle-stimulating hormone (FSH), and preference-elevated androgens. Luteinizing-releasing hormone (LRH) was administered intravenously via a portable infusion pump. Doses varied between 5 and 40 micrograms/pulse given at 60-, 90-, or 120-minute intervals. In 11 women, 85 treatment units (TUs) were completed, of which 74 were ovulatory, showing no specific advantage of any particular pulse dose or pulse interval. Five pregnancies occurred in three women. Two women did not ovulate during 52 and 284 consecutive days of therapy, respectively. Oligomenorrheic patients with PCOD can be made more regular by means of LRH, not necessarily leading to a regular menstrual cycle. In general, LRH is sufficient for luteal support. No signs of hyperstimulation were observed, although two patients incidently developed unilocular cysts with a maximum diameter of 8 cm. Ovulation induction with LRH in PCOD is possible, although the disease itself does not change during therapy. This may be further evidence that altered hypothalamic LRH secretion is more the result, rather than the cause, of the phenomenon of PCOD.
