Seminiferous tubules are located within the testicles, and are the specific location of meiosis, and the subsequent creation of male gametes, namely spermatozoa.
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 ...
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.

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).
Cross-section of a seminiferous tubule of the testis of a rat (250x) The function of Sertoli cells in the Amniota and Anamniota is the same, but they have slightly different properties when compared to each other. Anamnionts (fish and amphibians) employ cystic spermatogenesis in order to produce sperm cells. [22]
In mammals, spermatozoa are produced in the seminiferous tubules and flow into the epididymal duct. The end of the epididymis is connected to the vas deferens. The vas deferens ends with an opening into the ejaculatory duct at a point where the duct of the seminal vesicle also joins the ejaculatory duct. [1]
High-power view of a seminiferous tubule with normal spermatogenesis. Spermatogenesis is the process by which haploid spermatozoa develop from germ cells in the seminiferous tubules of the testicle. This process starts with the mitotic division of the stem cells located close to the basement membrane of the tubules. [1]
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.
