title: [The influence of bromocriptine-induced pregnancy and delivery on infertile cases with pituitary microadenoma].
abstract: Two consecutive pregnancies were induced in three hyperprolactinemic primary infertile patients bearing intrasellar microadenoma without visual disturbance. Pretreatment prolactin levels, 224 -496ng/ml, were normalized by 10-22.5mg/day of bromocriptine and the initial conceptions occurred. No abnormal sign due to pituitary enlargement was detected throughout the period of gestation and they delivered single full-term babies. Since no significant change was observed in puerperium, it was decided to give the second bromocriptine therapy. The prolactin levels, 80-190ng/ml, measured before the second therapy were apparently lower than those seen prior to the first therapy and the minimum effective dose used to induce the second pregnancy (5-7.5mg/day) was identical to 1/3-1/2 of the first one. The course of the second pregnancy of each case was also uneventful and the babies were all normal and mature. The magnitude of the rise in the prolactin level during the second pregnancy was smaller than that observed during the first pregnancy. The present longitudinal study throughout two consecutive pregnancies in three cases indicates that resolution of prolactinoma was resulted in some extent after withdrawal of stimulative factors associated with pregnancy. Hence, hyperprolactinemic infertile cases with intrasellar microadenoma can be subjected to bromocriptine therapies inducing consecutive pregnancies under intensive follow-up.
