Affiliation 1 Department of The pituitary glands are made of the anterior lobe and posterior lobe. The anterior lobe produces and releases hormones. The posterior lobe does not produce hormones per se—this is done by nerve cells in the hypothalamus—but it does release them into the circulation. Hormones from the hypothalamus mediate interactions between the nervous and endocrine systems by controlling the activity of specific target cells in the anterior pituitary gland.
FSH, a key hormone in mammalian reproduction, is produced mainly in the anterior pituitary gland, and the target organs are the ovary and testis.

These are made in the hypothalamus and stored in the posterior pituitary. ADH Oxytocin Anterior pituitary is a gland at the base of the brain in vertebrate animals that is divided into two regions, anterior and posterior, each of which secretes important hormones. Hormones secreted by the anterior pituitary influence growth, sexual development, skin pigmentation, thyroid function, and adrenocortical function. The anterior pituitary receives signaling molecules from the hypothalamus, and in response, synthesizes and secretes seven important hormones including thyroid-stimulating hormone and growth hormone.
