Male Reproductive System: Functions

The male reproductive system has several functions that are very important including producing, maintaining, and transporting sperm and semen, with the end results being discharged within the female reproductive system, during sexual intercourse.

This system consists of several different organs and structures including;

  • Penis the male sexual organ operates like a duct for urine and semen.
  • Glans penis is found on the end of the penis. It is very sensitive just like the clitoral glans (female sex organ) and layered with mucosa (pink colored, moist tissue). In uncircumcised males, the glans acts as a foreskin, which is normally removed, during a circumcision.
  • Corpus cavernosum (runs along the sides) and corpus spongiosum (runs along the front, ends at the glans) are tissues that fills with blood and causes an erection.
  • Urethra is a tube that is used to remove urine from the bladder. It attaches the bladder and the meatus (penis opening), so this can be possible.
  • Vas Deferens is a tube that transports sperm from the epididymis to the penis.
  • Epididymis organ stores mature sperm and creates the coiled beginning of the vas deferens.


  • A pair of glands (seminal vesicles) is responsible for producing about seventy percent of the semen (seminal fluid). This secretion is made up of amino acids, enzymes, citrate, fructose, vitamin C, phosphorylcholine, and proteins.
  • Testes are endocrine glands that have the same identical appearance. They are found in the scrotum and produce about five percent of semen (spermatozoa).
  • Prostate gland envelopes the urethra and produces about thirty percent of semen. This secretion is made up of citric acid, zinc, acid phosphatase, and prostate specific antigen.
  • Bulbourethral Glands (Cowper Gland) exocrine glands, which are located below the prostate. It produces less than one percent of semen. This secretion contains and sialic acid mucus, which has a jelly like consistency.

Seminal fluid contains prostaglandins, which suppresses the female immune system and prevents the female’s body from rejecting the semen. If the male experiences low levels of zinc, his sperm may become fragile and have lower fertility rate.

Blood flows into the penis, when a male becomes sexually aroused, which causes an erection. The blood vessels engorge with blood, due to a response from the nerves.
