To investigate both the release and synthesis of gonadotropins in the anterior pituitary gland, twice administrations of synthetic LH-RH at 60 minute interval on 19 normal cycling and 5 postmenopausal women and 5 male adults were performed. Serum LH and FSH of blood samples collected at 0', 30', 60', 90' and 120' were measured by radioimmunoassays and the pituitary functions for gonadotropin release (Δ1) and synthesis (Δ2) were analysed.In preovulatory phase, postmenopausal women and adult males, of of both LH and FSH were dominant than Δ2 while Δ1 were smaller than Δ2 in the groups of follicular phase and luteal phase. These results indicated that LH-RH two step test was a more useful method as compared to single LH-RH test to investigate both release and synthesis of pituitary gonadotropic hormones.
