Key Features/ Anatomical Relations

The lobules consist of one to four seminiferous tubules and interstitial tissue (consisting of blood vessels, nerves, Leydig cells, and macrophages).

Function

The lobules serve as the location for seminiferous tubules (which are responsible for the production of sperm) and Leydig cells (which are responsible for the production of testosterone).
