It connects the testicle to the vas deferens in the male reproductive system. The epididymis serves as an interconnection between the multiple efferent ducts at the rear of a testicle (proximally), and the vas deferens (distally). Its primary function is the storage, maturation and transport of sperm cells.
A testicle or testis (pl. testes) is the gonad in all male bilaterians, including humans, and is homologous to the ovary in females. Its primary functions are the production of sperm and the secretion of androgens, primarily testosterone. The release of testosterone is regulated by luteinizing hormone (LH) from the anterior pituitary gland.
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 visceral layer of tunica vaginalis of testis (lamina visceralis tunicae vaginalis testis) [4] is the portion of the tunica vaginalis that covers the testis and epididymis. It is the superficial-most of the three layers that constitute the capsule of the testis, with the tunica albuginea of testis situated deep to it.
By the time the testis is in the scrotal sac, the gubernaculum is no more than a remnant of scar like tissue. [10] Male germ cells formed in the testes are capable of special DNA repair processes that function during meiosis to repair DNA damages and to maintain the integrity of the genomes that are to be passed on to progeny.

The septa testis are fibrous partitions of the testis dividing the testis into compartments - the lobules of the testis. The septa are formed by extensions of the tunica albuginea - the dense fibrous connective tissue surface covering of the testis - into the substance of the testis. The septa converge towards the mediastinum testis. [1]
The connective tissue of the tunica albuginea testis extends into the substance of the testis to form fibrous partitions - the septa testis. [1] At the posterior aspect of the testis (where the serosa of testis is deficient to allow for the attachment of the epididymis), the tunica albuginea extends into the testis to form the mediastinum ...
Sertoli cells function to nourish the developing sperm cells. They secrete androgen-binding protein, a binding protein which increases the concentration of testosterone. There are two types: convoluted and straight, convoluted toward the lateral side, and straight as the tubule comes medially to form ducts that will exit the testis.
