Prolactin
Prolactin, also known as lactotropin, is a powerful hormone contributing to hundreds of essential bodily processes, most notably lactation and breast tissue development. High prolactin levels are a natural sign of pregnancy or breastfeeding, but abnormally elevated levels can cause significant symptoms in both men and women. If you are experiencing irregular periods, unexplained infertility, galactorrhea (milky discharge), or erectile dysfunction, this test is key to uncovering the underlying cause. Understanding your prolactin level is imperative for diagnosing conditions that affect reproductive health and normal lactational capabilities. Get tested to see if hormonal imbalances are contributing to your health concerns.
