The signs and symptoms of hypopituitarism vary, depending on which hormones are undersecreted and on the underlying cause of the abnormality. The diagnosis of hypopituitarism is made by blood tests, but often specific scans and other investigations are needed to find the underlying cause, such as tumors of the pituitary, and the ideal treatment ...
Hypogonadotropic hypogonadism (HH), is due to problems with either the hypothalamus or pituitary gland affecting the hypothalamic-pituitary-gonadal axis (HPG axis). [1] Hypothalamic disorders result from a deficiency in the release of gonadotropic releasing hormone ( GnRH ), while pituitary gland disorders are due to a deficiency in the release ...
Kisspeptin is a protein that regulates the release of GnRH from the hypothalamus, which in turn regulates the release of LH and, to a lesser extent, FSH from the anterior pituitary gland. Kisspeptin and its associated receptor KISS1R are known to be involved in the regulation of puberty.
Hypergonadotropic hypogonadism (HH), also known as primary or peripheral/gonadal hypogonadism or primary gonadal failure, is a condition which is characterized by hypogonadism which is due to an impaired response of the gonads to the gonadotropins, follicle-stimulating hormone (FSH) and luteinizing hormone (LH), and in turn a lack of sex steroid production.

The symptoms depend on what part of the pituitary is affected. Lymphocytic adenohypophysitis (LAH) occurs when the anterior pituitary cells are affected by autoimmune inflammation resulting in either no symptoms, adrenal insufficiency (if the ACTH producing cells are affected), hypothyroidism (if the TSH producing cells are damaged), or ...
The failure to breastfeed and amenorrhea no more periods, were seen as the syndrome (a collection of symptoms), but we now view Sheehan's as the pituitary failing to secrete 1-5 of the 9 hormones that it normally produces (the anterior (front) lobe of the pituitary produces FSH, LH, prolactin, ACTH (Adreno-cortico-trophic hormone),TSH (Thyroid ...
Follicle-stimulating hormone (FSH) is a gonadotropin, a glycoprotein polypeptide hormone. [1] FSH is synthesized and secreted by the gonadotropic cells of the anterior pituitary gland [ 2 ] and regulates the development, growth, pubertal maturation , and reproductive processes of the body.
Hemorrhage from a Rathke's cleft cyst, a remnant of Rathke's pouch that normally regresses after embryological development, may cause symptoms that are indistinguishable from pituitary apoplexy. [4] Pituitary apoplexy is regarded by some as distinct from Sheehan's syndrome , where the pituitary undergoes infarction as a result of prolonged very ...
