Prolactinoma is a condition in which a noncancerous tumor (adenoma) of the pituitary gland in your brain overproduces the hormone prolactin. The major effect is decreased levels of some sex hormones — estrogen in women and testosterone in men.
Although prolactinoma isn't life-threatening, it can impair your vision, cause infertility and produce other effects. Prolactinoma is the most common type of hormone-producing tumor that can develop in your pituitary gland.
Doctors can often treat prolactinoma with medications to restore your prolactin level to normal. Surgery to remove the pituitary tumor also might be an option.
