Luteal phase quality was evaluated in 32 patients wih nonstimulated cycles after laparoscopic oocyte recovery for in vitro fertilization. A luteal phase deficiency occurred in two cases (6.2%), the mean duration of the luteal phase was 13.5 +/- 1.3 days in 30 patients, and two patients developed amenorrhea of 23 and 43 days respectively after laparoscopy in spite of normal progesterone values 7 and 9 days after oocyte recovery. Six embryo transfers were performed after fertilization and regular cleavage of the obtained oocytes. No pregnancy resulted from the embryo transfers, although the patients had apparently normal luteal phases. In one patient there was a transient beta-subunit human chorionic gonadotropin (beta-hCG) elevation in serum. Luteal phase deficiency should not be main cause of a nonsuccessful embryo transfer. However, a prophylactic luteal phase support after oocyte recovery and embryo transfer in nonstimulated cycles is proposed.
