The pituitary gland produces prolactin.
Understanding Prolactin and the Pituitary Gland
Prolactin (PRL) is a hormone primarily known for its role in milk production (lactation) in women. However, it also has other functions throughout the body. The pituitary gland, a small gland situated at the base of the brain, is responsible for the synthesis and release of this crucial hormone. Multiple sources confirm this fact:
- MedlinePlus: A prolactin (PRL) test measures the level of prolactin in your blood. Prolactin is a hormone produced by the pituitary gland. https://medlineplus.gov/lab-tests/prolactin-levels/
- Cleveland Clinic: The pituitary gland, a pea-sized gland at the base of your brain, makes and releases (secretes) prolactin. https://my.clevelandclinic.org/health/articles/22429-prolactin
- Your Hormones: Prolactin is a hormone produced in the pituitary gland. https://www.yourhormones.info/hormones/prolactin/
- UpToDate: Prolactinomas, tumors of the pituitary gland, produce excessive prolactin. https://www.uptodate.com/contents/high-prolactin-levels-and-prolactinomas-beyond-the-basics/print
- NIDDK: A prolactinoma is a noncancerous tumor of the pituitary gland that overproduces prolactin. https://www.niddk.nih.gov/health-information/endocrine-diseases/prolactinoma

The Pituitary Gland's Role
The pituitary gland plays a vital role in the endocrine system, regulating various bodily functions through hormone production and release. Its production of prolactin highlights its importance in reproductive health and other physiological processes. Disruptions in prolactin production, often due to pituitary gland tumors (prolactinomas), can lead to conditions like hyperprolactinemia.
