Abstract
Treatment with a combination of luteinizing hormone-releasing analogue (GnRHa, Buserelin) and pulsatile administration of hMG (Group I) were used to induce ovulation in nine patients with polycystic ovary syndrome (PCO). The same patients were also treated with pulsatile hMG administration alone (Group II). Ovulation was observed in all twelve treatment cycles in Group I, and there were two pregnancies. In Group II, ovulation occurred in 22 of 26 treatment cycles. Ovarian hyperstimulation occurred in one cycle of Group I and in 5 of 26 cycles of Group II. The total dose per cycle of hMG to indcue ovulation in Group I was significantly lower than that needed when only pulsatile hMG administration was used. In response to Buserelin administration, the concentrations of serum luteinizing hormone (LH) and follicle stimulating hormone (FSH) increased transiently and then declined to the normal range observed in the early follicular phase. The concentrations of FSH increased in response to hMG administration, resulting in a normal LH/FSH ratio. The present data demonstrated that pulsatile subcutaneous administration of hMG in addition to Buserelin was effective in inducing follicular maturation and ovulation in patients with PCO with a lower incidence of serious side-effects.
