title: Serum progesterone levels in women treated with human menopausal gonadotropin and human chorionic gonadotropin for in vitro fertilization.
abstract: For evaluation of the adequacy of luteal function after in vitro fertilization-embryo transfer (IVF-ET), serum progesterone (P) levels were measured on days 3, 7, and 10 after laparoscopic follicle aspiration. Fifty-six infertile patients were treated during 86 cycles with human menopausal gonadotropin-human chorionic gonadotropin (hMG-hCG) for stimulation of follicular development. Serum estradiol (E2) levels were measured daily during hMG-hCG treatment. P levels were determined in 67 cycles. The mean (+/- standard deviation [SD]) of the sums of 3 P levels was 55.63 +/- 24.13 ng/ml. There were 11 pregnancies. The mean of the sums of 3 P levels of pregnant patients was 64.45 +/- 26.23 ng/ml and of 56 nonpregnant cycles was 53.90 +/- 23.35 ng/ml. The duration of luteal phase varied from 9 days to 15 days. The mean of the sums of 3 P values of patients with different luteal phase lengths ranged from 28.8 ng/ml to 60.51 +/- 25.68 ng/ml. The mean of the sums of 3 P levels of women with normal luteal phase and that of women with luteal phase defect by endometrial biopsy study were used as controls for comparison. There was poor correlation (r = 0.3441) between E2 peak levels and P levels; the sum of 3 P levels did not indicate luteal phase inadequacy in IVF-ET patients; and the majority of the nonpregnant cycles (32/56) showed a luteal phase of 11 days or less, in spite of adequate P levels.(ABSTRACT TRUNCATED AT 250 WORDS)
