ResumoSerum concentrations of seven different hormones were analyzed during 189 singleton conception cycles. One hundred nine women were treated with human menopausal gonadotropin (hMG), 52 women received clomiphene citrate (CC), and 28 became pregnant spontaneously. Serum progesterone (P) levels in hMG-treated women started to increase on day 18 of the cycle and reached peak concentrations between days 28 and 32 of the cycle. Serum estradiol (E2) concentrations paralleled the P patterns. In hMG-treated women, there were significant correlations between serum E2 and P concentrations and the number of the mature follicles observed before ovulation (both P < 0.01). CC-treated and spontaneous conception cycles revealed significantly lower serum levels of P, E2, testosterone, 17α-hydroxyprogesterone, and prolactin, compared with hMG-treated cycles (P < 0.05). Elevations of the gonadal steroids in hMG-treated women possibly reflect the multiple corpora lutea formed after multiple ovulations.
