Fertility and Sperm Production

Sperm is manufactured in the testicles which are located in the scrotum. Sperm production takes approximately 80 days and is a continuous production for most of an adult male’s life. Immature sperm cells start to develop and grow in the seminiferous tubules. These tubules are connected to the epididymis situated above the testes. It is here the developing sperm pass into. The epididymis stores the sperm while it continues to grow and in that growth starts to become motile. After approximately 2 weeks the sperm are mature. It is through masturbation or sexual intercourse that they are released from the epididymis. During ejaculation the sperm is pushed through to the urethra by contractions in the vas deferns. The urethra provides the sperm with access out of the body via the penis. The urethra also connects the bladder to the penis.
