TT3 is the main hormone that thyroid hormone does to various target organs. The serum TT3 concentration reflects the thyroid gland’s ability to function better than the thyroid gland. TT3 is an important indicator of early hyperthyroidism and the monitoring of recurrent hyperthyroidism and pseudo thyrotoxicosis.
Thyroid stimulating hormone(TSH) is a hormone secreted by adenohypophysis to promote the growth and function of the thyroid gland. The changes of TSH is noted prior to the T4 and T3 for months or years, as is of great value for the diagnosis of thyroid dysfunction and lesions.
Anti-Mullerian hormone (AMH), also known as Mullerian-inhibiting hormone (MIH), is a glycoprotein hormone structurally related to inhibin and activin from the transforming growth factor beta superfamily, whose key roles are in growth differentiation and folliculogenesis.
Estradiol (E2), is an estrogen steroid hormone and the major female sex hormone. It is involved in the regulation of the estrous and menstrual female reproductive cycles. Estradiol is responsible for developing female secondary sexual characteristics and is important in the development and maintenance of female reproductive tissues.
Prolactin is the hormone that tells the body to make breast milk when a person is pregnant or breast-feeding. Production of prolactin takes place in the pituitary gland. For those who are not pregnant or breast-feeding, there are only low levels of prolactin in the body.
Luteinizing hormone is a hormone produced by gonadotropic cells in the anterior pituitary gland. In females, an acute rise of LH ("LH surge") triggers ovulation and development of the corpus luteum. In males, where LH had also been called interstitial cell‒stimulating hormone (ICSH), it stimulates Leydig cell production of testosterone. It acts synergistically with follicle-stimulating hormone (FSH).
FSH is synthesized and secreted by the gonadotropic cells of the anterior pituitary gland, and regulates the development, growth, pubertal maturation, and reproductive processes of the body. FSH and luteinizing hormone (LH) work together in the reproductive system.
