By Mayo Clinic staffProlactinoma is a condition in which a noncancerous tumor (adenoma) of the pituitary gland in your brain overproduces the hormone prolactin. The major effect of increased prolactin is a decrease in normal levels of sex hormones — estrogen in women and testosterone in men.
Although prolactinoma isn't life-threatening, it can cause visual impairment, infertility and other effects. Prolactinoma is one of several types of tumors that can develop in your pituitary gland.
Doctors often are able to effectively treat prolactinoma with medications to restore your prolactin level to normal. Surgery to remove the pituitary tumor also may be an option to treat prolactinoma.
