Spontaneous pregnancy after a pregnancy induced by treatment in hyperprolactinemic women.
The relationship between spontaneous pregnancy of hyperprolactinemic patients after a first pregnancy induced by treatment and their serum prolactin levels was examined. Of the 100 patients with hyperprolactinemia studied, 74 became pregnant after treatment; namely, 20 transsphenoidal adenomoidectomy for pituitary prolactinoma (group 1), 26 on treatment with bromocriptine for pituitary prolactinoma (group 2), and 28 on treatment with bromocriptine for hyperprolactinemia without prolactinoma (group 3). After delivery in the first pregnancy, the rates of menstrual restoration and subsequent spontaneous pregnancy in group 1 (72.2% and 75.0%) were significantly (p less than 0.05) higher than those in group 2 (32.0% and 25%) and group 3 (13.6% and 18.2%). The serum levels of prolactin after the first pregnancy and weaning were significantly (p less than 0.05) lower in patients with subsequent spontaneous pregnancy than in patients without spontaneous pregnancy in each group, and the levels in patients with spontaneous pregnancy were significantly (p less than 0.05) lower in group 1 (15.2 +/- 8.8 ng/ml) than in group 2 (46.6 +/- 2.9 ng/ml). These data suggest that the transsphenoidal adenomoidectomy for pituitary prolactinoma may be better than bromocriptine treatment for recovery of reproductive function.
