Leydig cells release a class of hormones called androgens (19-carbon steroids). [8] They secrete testosterone, androstenedione and dehydroepiandrosterone (DHEA), when stimulated by the luteinizing hormone (LH), which is released from the anterior pituitary in response to gonadotropin releasing hormone which in turn is released by the hypothalamus.
The Leydig cells produce testosterone under the control of LH. LH binds to LH receptors on the membrane surface of Leydig cells. LH binds to LH receptors on the membrane surface of Leydig cells. Binding to this receptor causes an increase in cyclic adenosine monophosphate (cAMP), a secondary messenger, which allows cholesterol to translocate ...
Inhibin can bind specifically to testicular interstitial cells throughout development and may be an important regulator of Leydig cell testosterone production or interstitial cell function. [8] The inhibin beta B subunit joins the α subunit to form a pituitary FSH secretion inhibitor. Inhibin has been shown to regulate gonadal stromal cell ...
Testosterone is also synthesized in far smaller total quantities in women by the adrenal glands, thecal cells of the ovaries, and, during pregnancy, by the placenta. [158] In the testes, testosterone is produced by the Leydig cells. [159] The male generative glands also contain Sertoli cells, which require testosterone for spermatogenesis.
LH binds to the interstitial cells, causing them to secrete testosterone. Testosterone is required for normal spermatogenesis and inhibits the hypothalamus. Inhibin is produced by the spermatogenic cells, which, also through inactivating activin, inhibits the hypothalamus. After puberty these hormones levels remain relatively constant.
Interstitial cell refers to any cell that lies in the spaces between the functional cells of a tissue. Examples include: Interstitial cell of Cajal (ICC) Leydig cells, cells present in the male testes responsible for the production of androgen (male sex hormone) A portion of the stroma of ovary; Certain cells in the pineal gland; Renal ...
There may be some link with cognitive function as well,” says Jamie Stanhiser, ... “Testosterone doesn’t drop off like estrogen does—it goes down a linear decline,” says Casperson ...
Between tubules (interstitial cells) exist Leydig cells [10] – cells localized between seminiferous tubules that produce and secrete testosterone and other androgens important for puberty (including secondary sexual characteristics like facial hair), sexual behavior, and libido. Sertoli cells support spermatogenesis. [11]
