Seminiferous tubules are located within the testicles, and are the specific location of meiosis, and the subsequent creation of male gametes, namely spermatozoa.
It is located in the walls of the seminiferous tubules and supplies nutrients to sperm. [5] They are responsible for the differentiation of spermatids, the maintenance of the blood-testis barrier, and the secretion of inhibin, androgen-binding protein and Müllerian-inhibiting factor. [citation needed]
The walls of seminiferous tubules are lined with primitive germ layer cells and by Sertoli cells. [1] The barrier is formed by tight junctions, adherens junctions and gap junctions between the Sertoli cells, which are sustentacular cells (supporting cells) of the seminiferous tubules, and divides the seminiferous tubule into a basal compartment (outer side of the tubule, in contact with blood ...
Peritubular myoid cells surround the seminiferous tubules. [9] 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 are a type of sustentacular "nurse" cell found in human testes which contribute to the process of spermatogenesis (the production of sperm) as a structural component of the seminiferous tubules. They are activated by follicle-stimulating hormone (FSH) secreted by the adenohypophysis and express FSH receptor on their membranes.
Each lobule is contained in one of the intervals between the fibrous septa which extend between the mediastinum testis and the tunica albuginea, and consists of from one to three, or more, minute convoluted tubes, the seminiferous tubules (tubuli seminiferi).
Leydig cells, also known as interstitial cells of the testes and interstitial cells of Leydig, are found adjacent to the seminiferous tubules in the testicle and produce testosterone in the presence of luteinizing hormone (LH).
The seminal tract is a part of the male reproductive system and consists of seminiferous tubules (tubuli seminiferi recti, rete testis, efferent ducts), epididymides , Vas deferens and ejaculatory ducts.
