Prolactin is a hormone produced by the pituitary gland, located at the base of the brain. It plays a key role in various functions, primarily related to reproduction and lactation. While it is most commonly associated with milk production in breastfeeding women, prolactin is also present in men and non-pregnant women, where it has other important roles.
Prolactin matters for health because it helps regulate important biological processes, including reproductive functions and metabolism. Abnormal levels of prolactin can lead to various health issues. High levels in women can cause menstrual irregularities, while elevated levels in men can lead to decreased testosterone and infertility. Monitoring prolactin levels can be important in evaluating certain health conditions.
The basic function of prolactin in the body includes stimulating breast milk production after childbirth. It also plays a role in the development of breast tissue during pregnancy. Beyond lactation, prolactin influences sexual satisfaction and affects the immune system. Therefore, maintaining balanced prolactin levels is essential for overall health.
In summary, prolactin is an important hormone with significant roles in lactation and reproductive health. Understanding its function can help in identifying and managing various health concerns related to hormone levels.
