Abnormal Prolactin Levels and Pituitary- Gonadal Axis in the Puerperium

from the Departments of Obstetrics and Gynecology and of Clinical Chemistry, Herlev Hospital, and the Department of Obstetrics and Gynecology YA, Rigshospitalet, Copenhagen, Denmark

Abstract

To investigate the influence of breast-feeding and prolactin secretion on the pituitary-gonadal function, 3 different groups of patients were studied during the first 8 weeks of the puerperium. Group A comprised patients with hyperprolactinemia and secondary amenorrhea who conceived while on a regimen of bromocriptine. Group B was composed of normal lactating women. Group C comprised nonlactating women treated with bromocriptine. Group A patients had a normal decline in serum prolactin levels during the early postpartum period, but serum prolactin remained completely unaltered after clearance of placental estradiol. In group B suckling increased serum prolactin and suppressed luteinizing hormone. This pattern was not seen in group A. Group C patients had a rapid postpartum normalization of the pituitary-gonadal axis. The results indicate that in relation to lactation the pituitary function is rather autonomous in hyperprolactinemic patients.
