What's Tested
  • Prolactin

    Prolactin is a hormone released by the pituitary gland that plays a key role in both male and female reproductive systems. It is responsible for stimulating milk production, breast development and other bodily functions. This test measures the amount of prolactin in the blood. Prolactin levels typically rise during pregnancy and breastfeeding. Certain medicines can also increase prolactin levels. Elevated levels of prolactin can interfere with testosterone production, which may lead to a decrease in sperm production. High prolactin levels may also contribute to symptoms such as low libido, irregular menstruation, infertility, unexplained lactation and other health conditions.

FAQ

  • The prolactin level can provide important information related to reproductive health. An elevated prolactin level in women can indicate conditions such as hyperprolactinemia, which can lead to symptoms such as irregular or absent menstruation (amenorrhea), infertility or unexplained lactation outside of pregnancy or childbirth. In men, it can lead to symptoms such as low libido, erectile dysfunction, change in muscle mass and low energy. Testing your prolactin level can help you and your healthcare provider evaluate these symptoms.
