The rete testis (/ ˈ r iː t i ˈ t ɛ s t ɪ s / REE-tee TES-tis; pl.: retia testes) is an anastomosing network of delicate tubules located in the hilum of the testicle (mediastinum testis) that carries sperm from the seminiferous tubules to the efferent ducts. It is the homologue of the rete ovarii in females. [1]
The lobules are conical in shape, the base being directed toward the circumference of the organ, the apex toward the mediastinum testis. 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 ...
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.
The efferent ducts (also efferent ductules, ductuli efferentes, ductus efferentes, or vasa efferentia) connect the rete testis with the initial section of the epididymis. [1] There are two basic designs for efferent ductule structure: a) multiple entries into the epididymis, as seen in most large mammals.
Ultrasound image showing tubular ectasia of the rete testis as an incidental finding in an 81 year old male. Rete tubular ectasia, also known as cystic transformation of rete testis [1] is a benign condition, usually found in older men, involving numerous small, tubular cystic structures within the rete testis.
The male reproductive system includes testes, rete testis, efferent ductules, epididymis, sex accessory glands, sex accessory ducts and external genitalia. [3]Testosterone, an androgen, although present in both males and females, is relatively more abundant in males.
At nine weeks, male differentiation of the gonads and the testes is well underway. Internal changes include the formation of the tubular seminar Chris tubules in the rete testis from the primary sex cord. Developing on the outside surface of each testis is a Phibro muscular cord called the gubernaculum. This structure attaches to the inferior ...
It is the homologue of the rete testis in males. [2] It is a narrow hilus , at which nerves and vessels enter the ovary . In the medulla of the mammalian ovary near the hilus are small masses of blind tubules or solid cords—the rete ovarii—which are homologous with the rete testis in the male.
