This study was conducted to evaluate the prevalence of transient hyperprolactinemia in infertile women with luteal phase deficiency. One hundred fifty-one luteal phase deficiency patients and 11 controls had serum prolactin (PRL) measured daily for 3-4 days near ovulation. Thirty-three subjects (21.9%) had transient hyperprolactinemia, with PRL above 20 ng/mL for 1 or 2 days, and were studied further. The blood samples of these 33 subjects and of the controls were also analyzed for LH and FSH. Plasma progesterone was measured on the fourth, seventh, and tenth days after ovulation in both groups. The mean (+/- SD) of the mid-cycle integrated LH surge (125.0 +/- 23.0 mIU/mL; N = 26) and the sum of three plasma progesterone levels (23.8 +/- 4.5 ng/mL; N = 21) in the luteal phase deficiency women were significantly (P less than .001) lower than those of the controls (LH 158.7 +/- 13.8 mIU/mL; progesterone 33.8 +/- 6.5 ng/mL). All 33 luteal phase deficiency subjects with transient hyperprolactinemia were treated with bromocriptine at a dose ranging from 1.25-5 mg/day to maintain mid-cycle PRL levels between 5-15 ng/mL. Both the integrated LH surge and the sum of three progesterone levels increased significantly (P less than .05) during bromocriptine treatment, to 142.6 +/- 22.4 mIU/mL (N = 20) and 28.2 +/- 6.2 ng/mL (N = 18), respectively. Fourteen of the 33 patients conceived. The cumulative probability of conception was 31% for six cycles and 45% for 12 cycles of treatment.(ABSTRACT TRUNCATED AT 250 WORDS).
