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.

Bowel wall vascularity and peristaltic movement also are visible. Figure 8 Each testis is a compound tubular gland contained within a thick connective tissue coat called the tunica albuginea that also contains myofibroblasts that rhythmically contract. The basal compartment is closest to the basement membrane whereas the adluminal compartment is closer to the lumen of the seminiferous tubule.

The finding should not be confused with artifactual sloughing of germ cells caused by squeezing of the testis during necropsy dissection. These cells have abundant cytoplasm and extend from the basement membrane to the lumen. Sertoli cells have a characteristic oval nucleus with a dark nucleolus. The cytoplasmic contents and blood-testis barrier are better visualized under the electron microscope.

At 17, 23 and 28 days of age development of the seminiferous tubules, as judged by the formation of tubule lumens, was more extensive in the treated testes than in contralateral and sham operated controls. Tubule diameters were not necessarily correlated with lumen formation.

Testis is composed of convoluted seminiferous tubules in a stroma with Leydig cells Three layers: outer serosa (tunica vaginalis, extension of peritoneal cavity) with mesothelial cells; tunica albuginea (tough fibrous septa that extends into testis and separates it into 250 lobules of 1 - 4 seminiferous tubules), inner tunica vasculosa shows: a single seminiferous tubule, spermatogenesis, spermatogonia, spermatocytes (with chromosomes), spermatids, spermatozoa, and lumen. - testis stock pictures, royalty-free photos & images south african ground squirrel, goesciurus inauris, male in breeding condition, large testicles, central kalahari game reserve, botswana - testis stock from tubule to tubule depending in the stage of the spermatogenic cycle.
