Illustration of the Lobules of Testis

The Lobules of Testis are small, compartment-like structures found within the testes, the male reproductive organs responsible for the production of sperm and testosterone. Each testis is divided into numerous lobules, which contain the seminiferous tubules where sperm production takes place.

Anatomy

The testes are divided into about 200-300 conical lobules by thin fibrous septa. Each lobule contains one to three tightly coiled seminiferous tubules where sperm production occurs. The lobules and seminiferous tubules are surrounded by a layer of connective tissue called the tunica albuginea.

Function

The primary function of the lobules of testis is to provide a structured environment for the production and maturation of sperm. The seminiferous tubules within the lobules are the site of spermatogenesis, the process by which sperm cells are produced.

Clinical Significance

Abnormalities or damage to the lobules of testis can lead to conditions such as testicular torsion, testicular cancer, and infertility.
