Anatomy of the male urogenital system

The term urogenital is used in men as the reproductive and urinary systems merge. It consists of several parts:

  • Testes
  • Epididymis
  • Vas deference
  • Ejaculatory ducts
  • Urethra
  • Penis
  • Prostate
  • Other accessory glands


The testis is a firm, mobile organ, covered by a capsule and lying inside a sac call the scrotum. It is divided into lobules which contain the seminiferous tubules, which produce sperms and the male hormone, testosterone.


The epididymis is a coiled tube from the tail of which emerges the vas deference. IT stores and transports sperms

Vas deference:

The Vas deference transports sperms to the ejaculatory ducts

Ejaculatory ducts:

The two ejaculatory ducts unite with ducts emerging from the seminal vesicles, which are accessory glands that secrete fluid and empty into the part of the urethra that passes through the prostate


The male urethra extends from the urinary bladder to the external opening of the penis. Both urine and sperms pass through the urethra


The penis is made up of erectile tissue, corpus spongiosum in the middle and two corpus cavernosa on wither side. At the end of the corpus spongiosum is the head of the penis, where the urethra opens


The prostate is a part of the male reproductive system and is a plum or walnut sized gland, which lies just below the urinary bladder and surrounds the urethra (tube that takes urine from the bladder, along the penis and out of the body and also transports semen). The prostate has 3 lobes: one central and one each on either side and is partly muscular and partly glandular and has ducts that open into the prostatic portion of the urethra to carry the fluid it produces.

The prostate gland’s main purpose is to secrete the seminal fluid that carries sperm. During male climax, the muscular glands of the prostate help to propel the prostate fluid, in addition to sperm that is made in the testicles, into the urethra. The semen then leaves the body out through the tip of the penis during ejaculation.

The urinary system helps to eliminate wastes from the body, regulate blood volume, blood pressure, control levels of metabolites and electrolytes and consists of

  • Kidneys
  • Ureters
  • Bladder
  • Urethra


The kidneys are two bean shaped organs in the abdomen, made up of nephrons, which filter the blood and after further processing the wastes are exited from the body. The kidneys not only remove wastes but also create a water salt balance in the body and produce hormones


The ureter is a tube connecting each kidney to the bladder and enters the bladder at an angle to act as a valve which prevents backflow of urine. The ureters help transport urine to the bladder


The bladder receives urine from t eh ureters and stores it until one decides to pass urine, which is then transported through the urethra

Male urethra

The male urethra connects the bottom of the bladder to the outside opening. In men, it transports both urine and sperms.
