Plasma prolactin, human chorionic gonadotropin, estradiol, testosterone, and progesterone in the ovarian hyperstimulation syndrome.

Plasma prolactin, estradiol, progesterone, and testosterone, but not HCG-beta levels, were higher in a patient who developed the ovarian hyperstimulation syndrome while undergoing ovulation induction with human gonadotropins than in two other women who also became pregnant after similar treatment without complications. These results suggest that hyperprolactinema, in association with elevated ovarian steroid levels, may be factors in the pathogenesis of this disorder.
