testicular germ cells and cell debris in the epididymal lumen is a very sensitive indicator of disrupted spermatogenesis in the testis and subtle disturbances of 

Eventually, the sperm are released into the lumen and are moved along a series of ducts in the testis toward a structure called the epididymis for the next step of sperm maturation. Structure of Formed Sperm Sperm are smaller than most cells in the body; in fact, the volume of a sperm cell is 85,000 times less than that of the female gamete. The testicles (also called the testes; a single testicle is called a testis) are ovoid structures about 5 centimeters in length and 3 centimeters in diameter.

They are composed of developing sperm cells surrounding a lumen, the hollow center of the tubule, where formed sperm are released into the duct system of the testis. Specifically, from the lumens of the seminiferous tubules, sperm move into the straight tubules (or tubuli recti), and from there into a fine meshwork of tubules called the rete testes.

Lumen is built with testing in mind.

17  A vas deferens runs down from the anterior end of each testis to join the oviduct.

The principal androgen produced by the testes is testosterone. The production of testosterone by the testes is stimulated by  generative changes in both testes.
