Prolactin is a hormone that’s responsible for lactation, certain breast tissue development and milk production. Higher-than-normal levels of prolactin in your blood can cause certain symptoms, such as irregular periods, infertility and erectile dysfunction.
Prolactin is a polypeptide hormone responsible for lactation, breast development, and hundreds of other actions needed to maintain homeostasis. The chemical structure of prolactin is similar to the structure of growth and placental lactogen hormones.
The primary function of prolactin in fish is osmoregulation, [25] i.e., controlling the movement of water and salts between the tissues of the fish and the surrounding water.
How it works in the body. Prolactin encourages mammary glands in the breast to grow and develop. It nurtures breast tissue in the mammary glands called “mammary alveoli,” where...
Prolactin is a hormone named originally after its function to promote milk production in mammals in response to the suckling of young after birth. It also plays a key role in breast development during pregnancy.
Prolactin is one of the hormones produced by the anterior pituitary gland. It has a variety of roles but is particularly important in breast development and production of breast milk in females. This article will discuss prolactin, how its secretion is regulated and relevant clinical conditions.
The principal role of prolactin in mammals is the regulation of lactation. Prolactin is a hormone that is mainly synthesized and secreted by lactotroph cells in the anterior pituitary...
prolactin, a protein hormone produced by the pituitary gland of mammals that acts with other hormones to initiate secretion of milk by the mammary glands. On the evolutionary scale, prolactin is an ancient hormone serving multiple roles in mediating the care of progeny (sometimes called the “parenting” hormone).
Prolactin is a protein hormone of the anterior pituitary gland that was originally named for its ability to promote lactation in response to the suckling stimulus of hungry young mammals. We now know that prolactin is not as simple as originally described.
Prolactin’s functions include the regulation of behaviors that include maternal care, anxiety, and feeding as well as lactogenesis, hepatic bile formation, immune function, corpora lutea function, and more generally cell proliferation and differentiation.
