Does the pituitary gland produce testosterone

Hypopituitarism is characterized by a decreased secretion of hormones released by the anterior pituitary. For example, hypo-secretion of GH prior to puberty can be a cause of dwarfism . In addition, secondary adrenal insufficiency can be caused by hypo-secretion of ACTH which, in turn, does not signal the adrenal cortex to produce a sufficient amount of cortisol . This is a life-threatening condition. Hypopituitarism could be caused by the destruction or removal of the anterior pituitary tissue through traumatic brain injury, tumor, tuberculosis , or syphilis , among other causes. This disorder used to be referred to as Simmonds' disease but now according to the Diseases Database it is called Sheehan syndrome . [21] If the hypopituitarism is caused by the blood loss associated with childbirth, the disorder is referred to as Sheehan syndrome.

These tumors act and grow differently in every patient. A correct diagnosis and treatment plan is essential for the survival of many of us. Yes, clearly, in many they are slow growing and may cause little apparent outward damage. Regretably, many with so called "incidental" or "non-secreting" tumors often have symptoms which their physicians simply forget or are untrained to ask about. Sexual function, mental health, overall ability to function and fit in, are all vital aspects of our lives. The tumor may not "take" our life but may in fact change it to the point of lowering the patient and his or her family into a "living hell". Study, learn, seek expert help and join the PNA as we continue to bring you the REAL facts about these insidious diseases and their often fateful consequences.

Follicle-stimulating hormone (FSH) stimulates production of egg and sperm. It works alongside luteinizing hormone (LH) , which is the hormone that triggers ovulation in females and stimulates testosterone production in males. The action of adrenocorticotropic hormone (ACTH) is plain to see from its name because it stimulates the adrenal cortex to secrete hormones. Lastly, we see that the action of thyroid-stimulating hormone (TSH) is also plain to see from its name, because it is a hormone that stimulates the thyroid gland to produce hormones.

Summary . The thyroid system is regulated at many levels. Large-scale regulation is achieved via the pituitary-thyroid axis, which (with modulation provided by the hypothalamus to take into account an overall assessment of the body’s general needs), determines how much thyroid hormone the thyroid gland produces and releases. The levels of free circulating thyroid hormones that are available to the tissues are buffered, on a minute-to-minute basis, by TBG and the other thyroid-binding blood proteins. And, on an instantaneous basis, the actual binding of T3 to T3-nuclear receptors, at the site of a cell’s DNA, appears to be regulated by several intracellular proteins. This system of regulation makes sure that plenty of thyroid hormone is available at all times to the tissues, but at the same time allows for extremely fine control of the thyroid-DNA interface within individual cells.
