Serum FSH level may be an indicator of the functional potential of the ovary. The basic control of LH and FSH is by a negative feedback system involving the hypothalamus, anterior pituitary, and ovary. Basal serum FSH on day 3 of previous cycles in 36 patients underwent ovarian stimulation with a combination of GnRH agonist and FSH and hMG in an IVF program were evaluated. The results in this study show that a high basal serum FSH level is associated with a higher cancellation rate, a lower peak serum E2 level, lower number of oocytes retrieved and a lower clinical pregnancy rate.
