Low Testosterone (Low T)Read the Low Testosterone (Low T) article » What is testosterone?Testosterone is a steroid hormone which is made in the testes in males and in the ovaries in women (a minimal amount is also made in the adrenal glands). Testosterone has two major functions in the human body.
Testosterone production is regulated by hormones released from the brain. The hypothalamus and pituitary gland located in the brain produce hormonal signals that ultimately result in the production of testosterone. The hypothalamus is located just above the brain stem, and among its many functions, it produces gonadotrophin releasing hormone (GRH). GRH then travels a short distance to the pituitary gland, which is located in the base of the brain, and stimulates this gland to release FSH (follicle stimulating hormone) and LH (luteinizing hormone). These hormones travel through the bloodstream to activate the sex organs in both men and women. Subsequently, these hormones have a role in regulating testosterone levels in the bloodstream. The majority of testosterone circulates in the blood bound to a carrier protein (many hormones that are produced in one area and affect another area have a carrier protein that helps their travel through the bloodstream). In this case the carrier protein is called "sex hormone binding globulin," or SHBG. When testosterone is being carried by SHBG, it is considered "bound". Bound testosterone does not play an active role in the body; only the unbound or "free" testosterone is able to enter the differen...

A prolactinoma produces an excessive amount of the hormone prolactin. Prolactin is a natural hormone which supports a woman's normal lactation (breastfeeding). Prolactinomas are the most common type of pituitary tumor. Symptoms of prolactinoma are caused by pressure of the tumor on surrounding tissues or by excessive release of prolactin from the tumor into the blood (causing a condition known as hyperprolactinemia).
What is the normal function of prolactin?Prolactin stimulates the breast tissues to enlarge during pregnancy. After delivery of the baby, the mother's prolactin level falls unless she breastfeeds her infant. Each time the baby nurses from the breasts, prolactin levels rise to maintain milk production. What is the pituitary gland?Sometimes called the master gland, the ... Other Related Low Testosterone ArticlesEmergency Contact for Napa
