Women with polycystic ovary syndrome (PCOS) undergoing ovulation induction appear to be extremely sensitive to gonadotropin stimulation and at increased risk for ovarian hyperstimulation syndrome. To determine granulosa cell responsiveness to recombinant human FSH (r-hFSH), dose-response studies were conducted in 16 individual PCOS patients and 7 normal(More)
In PCOS women with insulin resistance, hyperinsulinemia may contribute to inappropriate gonadotropin secretion. To determine whether insulin influences gonadotropin release in PCOS, pulsatile LH secretion and gonadotropin responses to GnRH were evaluated before (phase 1) and during (phase 2) insulin infusion. In phase 1, 11 PCOS and 9 normal women on(More)
BACKGROUND AND OBJECTIVE In polycystic ovary syndrome (PCOS) inappropriate gonadotrophin secretion is characterized by increased pulse frequency and amplitude, elevated 24-h mean serum concentrations, and greater responses to GnRH. While the mechanism(s) responsible for this increased release of LH are not well understood, enhanced LH secretion has been(More)
CONTEXT In women with polycystic ovarian syndrome (PCOS), the relationship of insulin to LH secretion and responses to GnRH remains unresolved. A rigorous analytical examination of this relationship has not been performed. OBJECTIVE Our objective was to determine the relationship of basal LH secretion and responses to GnRH, insulin, and other endocrine(More)
Women with polycystic ovary syndrome (PCOS) are known to exhibit insulin resistance with compensatory hyperinsulinemia. To determine the role of hyperinsulinemia on follicle function in PCOS, we examined 24-h estradiol (E(2)) responses to recombinant human FSH (r-hFSH), 75 IU, before and during insulin infusion both before and after administration of(More)
It has been reported in women with polycystic ovary syndrome (PCOS) that LH secretion is not altered by insulin infusion. To determine whether insulin resistance may have precluded an effect of insulin, pulsatile LH secretion and gonadotropin responses to GnRH were examined in PCOS women (n = 9) before and after pioglitazone treatment (45 mg/d) for 20 wk in(More)
BACKGROUND Orthodox Jewish women are prohibited from participating in sexual intercourse from the start of menstruation to 7 days after the end of flow, when they participate in a ritual bath. CASE Two orthodox Jews with ovulation prior to initiating sexual intercourse were treated with oral contraceptives to delay ovulation. CONCLUSION Oral(More)
