What is (are) Prolactinoma ?
The pituitary gland, sometimes called the master gland, plays a critical role in regulating growth and development, metabolism, and reproduction. It produces prolactin and other key hormones including
                
- growth hormone, which regulates growth  - adrenocorticotropin (ACTH), which stimulates the adrenal glands to produce cortisol, a hormone important in metabolism and the body's response to stress  - thyrotropin, which signals the thyroid gland to produce thyroid hormone, also involved in metabolism and growth  - luteinizing hormone and follicle-stimulating hormone, which regulate ovulation and estrogen and progesterone production in women and sperm formation and testosterone production in men
                
The pituitary gland sits in the middle of the head in a bony box called the sella turcica. The optic nerves sit directly above the pituitary gland. Enlargement of the gland can cause symptoms such as headaches or visual disturbances. Pituitary tumors may also impair production of one or more pituitary hormones, causing reduced pituitary function, also called hypopituitarism.
