âHyperâ ( meaning over, super, or excess) or in this case Hyperprolactinemia â meaning one has an excess of prolactin or high prolactin levels. Hyperprolactinemia is a condition where non-pregnant women (or men) have too much or an excess of prolactin in their bodies.
During pregnancy, high circulating concentrations of estrogen and progesterone increase prolactin levels by 10- to 20-fold. However, at the same time, estrogen, as well as progesterone, inhibit the stimulatory effects of prolactin on milk production.hysiologic levels of prolactin in males enhance luteinizing hormone-receptors in Leydig cells, resulting in testosterone secretion, which leads to spermatogenesis. Prolactin also stimulates proliferation of oligodendrocyte precursor cells.
