Rete testis

Detailed explanation-1: -testes are composed largely of seminiferous tubules-coiled tubes, the walls of which contain cells that produce sperm-and are surrounded by a capsule, the tunica albuginea. Seminiferous tubules may constitute up to 90 percent of the testis.
Detailed explanation-2: -(i) Each testes has highly coiled 250 compartments called seminiferous tubules.
Detailed explanation-3: -A human has approximately 750-1200 seminiferous tubules. They are in charge of sperm production, maintenance, and storage. The testes contains seminiferous tubules. Sertoli cells surround and support germ cells as they differentiate and develop into mature Seminiferous tubules.
Detailed explanation-4: -There are about 250 lobules in each testis. Each lobule contains 1 to 4 highly coiled seminiferous tubules that converge to form a single straight tubule, which leads into the rete testis. Short efferent ducts exit the testes.
Detailed explanation-5: -The seminiferous tubules are the site of spermatogenesis where germ cells develop into spermatozoa in close interaction with Sertoli cells.
