Male Reproductive System

Penis: The male sex organ that allows the passage of semen and urine. 

​

Testes (Singular: testis): aka testicles. An average man should have two testes. The egg-shaped sacs produce sperm, which is essential for the fertilisation of eggs and production of children. They also produce hormones for sexual development. 

​

Epididymis: The ducts that sit just behind the testes. They connect the testes to the vas deferens. Infection of the epididymis is called epididymitis. 

​

Vas deferens: The tube that transports sperm from the epididymis to the urethra. It goes round behind the bladder and into the prostate. 

​

Prostate: Secretes seminal fluids produced by the seminal vesicles (see below). Semen is then transported to the urethra for ejaculation. 

​

Bladder: The organ that holds urine. 

​

Urethra: The tube that transports urine from the bladder as well as semen to the outside world. 

Seminal vesicles: Produces most of the seminal fluid 

​

The male reproductive organs are situated right in front of the rectum and anus, both of which transport faeces to the outside world.
