Video - Prolactinoma

A prolactinoma is a benign pituitary gland tumor that produces high levels of the hormone prolactin. Prolactin then suppresses the gonadotropin-releasing hormone resulting in symptoms like amenorrhea, galactorrhea, hypogonadism, gynecomastia, and erectile dysfunction in males. Treatment involves the use of dopamine agonist agents like bromocriptine which reduces the size of the tumor and lowers prolactin levels. In some cases, surgery or radiation therapy may also be required.
