WebFeb 4, 2024 · Leydig cells. Testosterone-secreting Leydig cells (named after Franz von Leydig, b. 1821), also called "interstitial cells," occur in clusters within the interstitial tissue () of the testis.. Leydig cells may be recognized not only by their location within the testicular interstitium but also by their round nuclei and extensive acidophilic cytoplasm. WebFunctions of Fetal Leydig cells. Although fetal Leydig cells are lost before adult Leydig cells start developing, they are involved in the development of the male reproductive tract (male sexual characteristics) in the embryo. Along with fetal Sertoli cells, fetal Leydig cells have been shown to produce androgens. A process called steroidogenesis.

WebMar 26, 2024 · Testosterone is synthesized by the Leydig cells of the testes as the end product of an elegant series of hormonal interactions known collectively as the HPG axis . The hypothalamus, located in the forebrain, secretes gonadotropin releasing hormone in a pulsatile fashion which then travels via the hypophyseal-portal system to reach the … WebIn both sexes, LH stimulates secretion of sex steroids from the gonads. In the testes, LH binds to receptors on Leydig cells, stimulating synthesis and secretion of testosterone. Theca cells in the ovary respond to LH stimulation by secretion of testosterone, which is converted into estrogen by adjacent granulosa cells.

WebSpermatogenesis is a multi-step process of male germ cell (Gc) division and differentiation which occurs in the seminiferous tubules of the testes under the regulation of gonadotropins – Follicle Stimulating Hormone (FSH) and Luteinising hormone (LH).
