What are the symptoms of prolactinoma?

The symptoms of prolactinoma may vary depending on the size of the tumor and the sex of the affected person. In some cases, especially when the tumor is still small, prolactinoma may not cause any noticeable symptoms. When symptoms occur in women, they often begin with irregular menstrual periods or a complete stop to menstrual periods. Women may also start producing breast milk, even if they're not pregnant or nursing. Men with prolactinoma may experience erectile dysfunction and, occasionally, decreased body hair. In both men and women, prolactinoma may cause low bone density, low sex drive, and infertility. If the tumor grows large enough to press on the optic nerve, it may cause headaches and problems with vision.
