Male Reproductive System
To understand how a vasectomy is performed, it is first essential to understand the anatomy and function of the male reproductive system. The testicles, or testes, produce sperm and the male hormone -testosterone.
The testis are located in the scrotum at the base of the penis and easily palpable (one can feel them). The scrotum is basically a pocket which protects the testis and maintains a normal temperature.
Each testis contains a thin long channel, called the epididymis, where sperm can be stored for as long as 6 weeks while they mature. The epididymis are connected to the prostate gland by a pair of tubes called the vas deferens. The vas deferens is part of a complex collection of blood vessels, nerves, and lymphatic channels called the spermatic cord. During ejaculation, seminal fluid produced by the prostate gland, which mixes with sperm from the testes to form semen, which then is ejaculated from the penis.
