What is a prolactinoma?

A prolactinoma is a noncancerous tumor of the pituitary gland. This tumor causes the pituitary to make too much of a hormone called prolactin. The major effect of prolactinoma is decreased levels of some sex hormones — estrogen in women and testosterone in men.

In women, these tumors cause decreased libido, infertility, altered menses, and milk discharge from their breasts. In men, these tumors induce impotence and decreased libido.
