Abstract
Bromocryptine treatment was administered to 15 patients with amenorrhea and galactorrhea (AG) and to 1 patient with amenorrhea. All of them had increased plasma PRL levels. Of these 16 patients, 4 had a normal sella turcica (ST; group STO), 4 had a slight enlargement (group ST +), and 7 had a clear enlargement of ST (ST++) but no evidence of suprasellar extension. Ovulation was restored in 15 patients by bromocryptine treatment only. In one patient, ovulation resumed only after human pituitary gonadotropin treatment in combination with bromocryptine. There was no correlation between basal prolactinemia, PRL stimulability or suppressibility, the size of ST, or the efficiency of bromocryptine treatment. Every patient with normal LH response to either LRH or clomiphene or both resumed ovulation. Ovulation resumed in 3 patients among the 4 with abnormal LH response to either LRH or clomiphene or both. Among the 14 who desired pregnancy, 13 became pregnant. To date, 12 patients (ST++, 5; ST+, 3; STO, 4) have delivered normal babies. The courses of pregnancy were normal. During pregnancy, no change of ST was noted on lateral and frontal skull x-ray performed in every patient at trimonthly intervals. There was no change in the sellar index in 10 patients after pregnancy, as compared to the pretreatment status. In the presence of a pituitary adenoma or in patients with hyperprolactinemia and amenorrhea and galactorrhea, bromocryptine treatment may cure sterility without pituitary complication during pregnancy.
