Reproduction. The ability of an organism to produce offspring of its own type is known as reproduction.

It is not necessary for the survival of an individual.

But it is necessary for the survival of species.

If the present member of the species dies, there will be no species of that organism as they did not reproduce.

Reproductive System Of A Man

Human reproduction requires internal fertilization.

The reproductive system of a man is unique in two ways.

Firstly, it is not “turned on” until the human hits puberty.

Secondly, the organ system of the body of males and females exhibit slight differences, whereas their reproductive systems are very different.

Male Reproductive System

The main function of the male reproductive system is to produce and maintain sperm.


The male reproductive system includes:

  1. Gonads.
  2. Accessory ducts.
  3. Accessory glands.
  4. Copulatory organ.


Testes are male gonads that are attached outside the body in a skin pouch called the scrotum.

Each testis contains a bunch of lobules.

And these lobules contain seminiferous tubules.

Spermatozoa are produced in these tubules.

Accessory Ducts

Once the spermatozoa are produced in the seminiferous tubules, they enter a tubular network called rete testis for further maturation.

Spermatozoa are then transported out of the testis through efferent ductules.

The epididymis is coiled on the outer surface of the testis.

Its function is to transport and store sperm.

Epidymis opens into another duct called the vas deferens which joins the duct to form a short ejaculatory duct.

Here, this ejaculatory duct enters the prostate gland, then empties into the urethra.

Urethra is also known as the urinogenital duct as it carries urine as well.

Copulatory Organ

This organ mainly consists of tissues that can fill with blood to cause an erection.

Accessory Glands

Reproduction. A pair of seminal vesicles is located at the junction of the sperm duct and ejaculatory duct.

The prostate gland encircles the urethra just below the bladder.

A pair of Cowper’s glands is situated at the junction of the ejaculatory duct and urethra.
