Testes. The testes are responsible for the production of sperm cells and the male sex hormone testosterone. The testes produce as many as 12 trillion sperm in a male’s lifetime, about 400 million of which are released in a single ejaculation.
Nerves, blood vessels, and lymphatic vessels travel through the spermatic cords to support the testes. The vas deferens also passes through the spermatic cord carrying sperm out of the testes toward the prostate and urethra.This diagram with labels depicts and explains the details of Photos Of Testis.
