The hormone-producing gland in the brain (pituitary gland) overproduces prolactin, decreasing the levels of some sex hormones. It's caused by a noncancerous tumor on the gland. Common symptoms include breast discharge and irregular menstrual periods in women. Men may experience decreased sexual desire and breast enlargement. Prolactinoma can cause impaired vision and infertility. Treatments include medications, surgery, and radiation.
