Prolactin (PRL) is secreted by the anterior pituitary gland. In women, it regulates lactation, menstrual cycles, and ovulation. In men, prolactin also plays a role in maintaining sexual function and hormonal balance.
Abnormal prolactin levels may cause amenorrhea, infertility, galactorrhea, or sexual dysfunction, making it an important marker for reproductive and endocrine health.
A venous blood sample is analyzed for serum prolactin levels. Results are interpreted with other sex hormones, imaging, and clinical history.
