A spermatocele refers to the cystic accumulation of semen in the male reproductive tract. Although it is thought to be caused by narrowing of the lumen of the excurrent duct with resultant cystic dilatation of the duct, the pathogenesis of the narrowing remains unknown. In the present study, we histologically examined spontaneous spermatoceles in

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. 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. The rete testis, the area where tubules coalesce and connect to efferent ductules, is shown as irregularly-shaped lumens lined by a simple cuboidal epithelium.

The male gonads, testes or testicles, begin their development high in the abdominal cavity, near the kidneys.During the last two months before birth, or shortly after birth, they descend through the inguinal canal into the scrotum, a pouch that extends below the abdomen, posterior to the penis.Although this location of the testes, outside the abdominal cavity, may seem to make them Find the perfect Testis stock photos and editorial news pictures from Getty Images.

The tunica albuginea, the fibromuscular connective tissue capsule of the testis, is thickened at the mediastinum testis, from which septa are derived to subdivide the testis into approximately 250 small, incomplete compartments, known as the lobuli testis.Tunica albuginea Lobuli testis Find the perfect Testis stock photos and editorial news pictures from Getty Images.

The volume of each component of the testis was determined as the product of the volume density and testis volume. Testicle or testis is the male reproductive gland or gonad in all animals, including humans. It is homologous to the female ovary. The functions of the testes are to produce both sperm and androgens, primarily testosterone. Testosterone release is controlled by the anterior pituitary luteinizing hormone; whereas sperm production is controlled both by the anterior pituitary follicle-stimulating hormone and gonadal testosterone.
