Prolactin (PRL)
PRL tumors are the most common pituitary tumor, accounting for between 35 and 45 percent of all cases. In women, PRL stimulates the breasts to produce milk. Excess PRL production causes inappropriate production of milk (galactorrhea), irregular menstrual cycles or cessation of menses (amenorrhea) and infertility. In men, excess PRL leads to impotence and infertility. This pituitary tumor occurs more frequently in women and is commonly found during their childbearing years. In men, it is usually discovered after age 50.
Prolactin secreting tumors often can be successfully treated with medication only. When this does not benefit the patient and tumors are small, radiosurgery may be considered.
