Definition: Adenohypophysis is a group of cells in the hypothalamus that produce sex hormones, including estrogen, testosterone, and progesterone. The term is also used to refer to the gland itself, which contains these substances. The adenohypophysis is located on the surface of the pituitary gland, just above the anterior pituitary gland. It receives its blood supply from the anterior pituitary gland. The hormones produced by the adenohypophysis include estrogen and testosterone. Estrogen helps to stimulate the growth of secondary sexual characteristics in females and to maintain a normal reproductive function in males. Testosterone is responsible for the development of male secondary sex characteristics, such as facial hair, chest growth, and the ability to gain weight. The production of these hormones is regulated by the hypothalamus. The hypothalamus coordinates the release of these hormones and stimulates the pituitary gland to secrete them at appropriate intervals. In summary, the adenohypophysis is a group of cells in the hypothalamus that produce sex hormones. It receives its blood supply from the anterior pituitary gland and has two main functions: stimulating secondary sexual characteristics and regulating the growth and development of male secondary sex characteristics.
