Prolaktinfrigjøring

Prolaktinfrigjøring refers to the release of prolactin, a hormone produced by the anterior pituitary gland. This hormone plays a crucial role in various physiological processes, most notably in lactation in females. The secretion of prolactin is primarily regulated by dopamine, which acts as an inhibitor. Therefore, conditions that decrease dopamine levels, such as stress, sleep, or suckling, lead to increased prolactin release.

Conversely, increased dopamine levels suppress prolactin secretion. Several factors can stimulate prolactin release, including pregnancy, breastfeeding, and certain medications. High levels of prolactin, known as hyperprolactinemia, can have various consequences. In women, this can lead to irregular menstrual cycles, infertility, and galactorrhea (inappropriate milk production). In men, high prolactin can result in decreased libido, erectile dysfunction, and infertility.

Diagnosing prolactin-related issues typically involves blood tests to measure prolactin levels, often alongside tests to identify underlying causes such as pituitary tumors or thyroid dysfunction. Treatment depends on the cause and may involve medication to lower prolactin levels or addressing the underlying condition. Understanding prolaktinfrigjøring is important for diagnosing and managing a range of endocrine disorders.
