Pituitary Hormones

The pituitary (hypophysis) is a small gland located near the base of the brain. The anterior and posterior parts of the pituitary gland release a large number of hormones that are crucial to the body’s objectives of survival and reproduction. These hormones trigger physiological effects in specific cells, tissues, and organs. The hormones of the anterior and posterior pituitary are particularly important for the maintenance of homeostasis in the body.

The pituitary gland releases Growth Hormone (GH), Thyroid Stimulating Hormone (TSH), Adrenocorticotrophic Hormone (ACTH), Prolactin, Follicle Stimulating Hormone (FSH), Melanocyte-stimulating Hormone (MSH), Oxytocin, and Anti-diuretic Hormone (ADH or Vasopressin). Excessive or inadequate production (or uptake) of any of these hormones can cause profound disease conditions.

Sigma-Aldrich offers a number of products to aid research focusing on the anterior and posterior parts of the pituitary gland and the hormones that they release to support the body’s physiological functioning.
