A prolactinoma is a benign tumor of the pituitary gland that secretes the hormone prolactin. Prolactin is the hormone that stimulates the breast to produce milk in women.
Signs and symptoms of a prolactinoma are caused by the excessive levels of the hormone prolactin. In women, these symptoms and signs can include
- absence of menstruation,
- irregular menstrual periods,
- loss of libido,
- vaginal dryness, and the
- production of breast milk in women who are not nursing.
The most common associated symptom in men is impotence. Men are more likely to experience headaches or vision problems caused by the size of the tumor since changes in menstruation are more likely to signal the presence of the tumor in women.
Cause of prolactinoma
The exact cause of prolactinoma is unknown, and most cases develop in people with no known family history of the condition.
