Sometimes called the master gland, the pituitary gland plays a critical role in regulating growth and development, metabolism, and reproduction. This gland produces prolactin and a number of other key hormones including:
Growth hormone, which as the name indicates, regulates growth.
ACTH (adrenocorticotropin hormone), which stimulates the adrenal glands to produce cortisol, especially during stressful events (surgery, etc.).
Thyroid stimulating hormone (TSH), which signals the thyroid gland to produce thyroid hormone.
Luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which regulate ovulation and estrogen and progesterone production in women, and sperm formation and testosterone production in men.
