Prolactin
Unexplained fatigue, low libido, irregular periods, or unexpected breast changes? These could be signs of abnormal prolactin levels. Prolactin is a hormone best known for its role in supporting milk production in women, but it also plays a role in hormonal balance for both sexes. In women, high prolactin can affect menstrual cycles and fertility, while in men, it may lead to reduced testosterone, erectile dysfunction, or decreased sex drive.

Essential information about your test
What's in the test
What we measure:
- Prolactin - Prolactin is a hormone made by the pituitary gland that plays an important role in reproductive and hormonal health. Its main job is to trigger milk production after childbirth, which is why levels naturally rise during pregnancy and breastfeeding. In men, prolactin helps regulate testosterone levels and reproductive function. Outside of these roles, elevated prolactin can signal a hormonal imbalance affecting fertility, libido, or sexual health in both women and men.
