Prolactin

Prolactin, produced by the pituitary gland, is a versatile hormone primarily recognized for its role in lactation and breastfeeding. Beyond its involvement in milk production, prolactin influences a range of physiological processes, including regulation of the immune system, metabolism, and behavior. It also plays a role in both male and female reproductive health by impacting sexual function and contributing to the menstrual cycle’s regularity. Even in expecting fathers, prolactin levels can experience an uptick, possibly contributing to the preparation for nurturing roles and parenthood.
