Prolactin is a hormone that plays an essential role in several bodily functions, including lactation, reproduction, and metabolism. While there are no exact synonyms for the word "prolactin," different terms are often used to refer to this hormone, depending on the context. Some common alternatives include lactogenic hormone, luteotropic hormone, mammotropic hormone, and lactotropin. Medical professionals and researchers may also use other technical terms to describe prolactin, such as anterior pituitary hormone, prolactotropic hormone, and PRL. While these names may differ slightly, they all refer to the hormone that regulates lactation, among other important functions in the human body.
