Explanation:

Gonads are the primary sex organs in the male which are the two testes.

Each testis is surrounded by the dense connective tissue capsule called tunica albuginea which is responsible for the thickening on the posterior side and forms mediastinum testis.  

From this region, the septa penetrate and divide it into about 250 pyramidal compartments (testicular lobules) . Each lobule is containing the sparse connective tissue with the endocrine interstitial cells that secrets testosterone, and also contains one to four highly convoluted seminiferous tubules which is responsible for sperm production.
