Testicles and epididymis
The testicles are male gonads. Their function is, on the one hand, to produce the male sex hormone testosterone and, on the other hands, to produce sperm. Sperm is stored in the epididymis, which is a delicate organ attached to the back of the testicle. The testis and epididymis are located in the scrotum outside the body. This location allows sperm production, as it is a slightly lower temperature than inside the body. The vascular and nerve supply come from the groin area via the spermatic cord.
