19001717 . Prolactin is a hormone produced by the pituitary gland that plays a key role in various physiological functions.
. Its primary purpose is to stimulate milk production (lactation) in women after childbirth. Prolactin levels naturally rise during pregnancy and breastfeeding to prepare and maintain milk supply. It also has a role in regulating reproductive health by influencing ovulation and menstrual cycles, as high levels can inhibit ovulation.
. In men and non-pregnant women, prolactin is involved in maintaining overall reproductive health, although its exact function is less defined. Elevated prolactin levels, a condition called hyperprolactinemia, can lead to symptoms like irregular menstrual cycles, infertility, or reduced libido.
. Prolactin testing is often performed to evaluate unexplained infertility, galactorrhea (milk secretion in non-pregnant individuals), or symptoms of pituitary gland disorders.
