Abstract

Five normally menstruating women were treated in an attempt to induce development of multiple follicles. They were randomly divided into two groups. The first group, consisting of three women, was treated with a combination of follicle stimulating hormone (FSH) and human menopausal gonadotropin (hMG) (combination FSH/hMG). The second group, two women, was treated with hMG only. Following a nonconceptual cycle, the treatments were exchanged. The increment patterns of serum estradiol during the follicular phase and progesterone levels in both groups were identical. Ultrasonographic scanning revealed similar number and size of the growing follicles, which subsequently terminated in the same oocyte recovery rate in both groups (7.6 ± 3.4 oocytes/procedure in the combination FSH/hMG and 8.0 ± 2.5 in the hMG-only group). Fertilization and cleavage rates were also similar. These data indicate that high FSH/LH levels in different ratios do not alter ovarian response and oocyte fertilization potential.
