Prolactin

Prolactin is a hormone primarily produced by the pituitary gland, a small gland located at the base of the brain. Its main role is to stimulate milk production after childbirth. Prolactin also plays a part in numerous other bodily functions, including metabolism, immune regulation, and reproductive health in both males and females. Its levels fluctuate throughout the day and can be influenced by various physiological states and external factors. Accurate measurement provides insight into endocrine function.
