What are the Human Male Sex Organs

Reproduction is a fundamental biological process that occurs in all living things in order to sustain their populations.

Human reproductive system, which consists of male and female genital organs, functions to produce an offspring, with the female providing an ovum and the male providing a sperm.

The male reproductive system consists of both external and internal organs which work together to provide the male gamete or sperm.

In this article, we shall discuss the male sex organs, in brief, to help you get a good understanding of how they work.

External Male Sex Organs

The external male reproductive organs include the following:

The Penis

This is the male organ that takes part in sexual intercourse.

It’s made up of three parts that are the root, the body, and the glans.

The penis is made of soft and spongy tissue which can contract or expand.

When a man is sexually aroused, the penis fills up with blood, and this causes the spongy tissue to stiffen thus causing an erection.

This erect state of the penis makes it easy to enter the vagina during sexual intercourse

The Scrotum

This is the loose sac of skin that hangs below the penis.

Its function is to house the testicles and maintain the right temperatures for sperm production.

For normal development of sperms, the temperature inside the testicles must slightly cooler than your body’s temperature.

The scrotum wall has special muscles that allow it to either relax, contract moving the testes away from the body for cooling or closer to the body to warm the temperatures.

The testes

Also known as the testicles, the testes are firm, mobile organs that are contained in the scrotum.

They are secured in the scrotum by the spermatic cord. Normally, men have 2 testes, and these are responsible for producing testosterone, which is the main male sex hormone.

Within the testicles are masses of coiled tubes known as seminiferous tubules.

These tubes are responsible for generating the sperm cells or male gametes through a process known as spermatogenesis.

Epididymis

This is a long, coiled tubule that is located on the backside of each testis.

Its functions are to carry and store the sperm cells that have been produced in the testicles.

Epididymis also helps to bring the sperm cells to maturity, because the sperms that are produced by the testicles are immature and incapable of fertilization.

When a man is aroused, contractions force the sperm cells into a structure called the vas deferens.

Internal Male Sex Organs

Also known as accessory organs, the internal male reproductive organs include the following:

Vas deferens

The is a long tube that connects the epididymis to the urethra.

It transports mature sperm cells to the urethra during arousal.

Urethra

This is the tube through which urine passes from the bladder to the outside.

In males, it also expels semen during ejaculation.

Seminal vesicles

These are pouch-like sacs that attach to the vas deferens.

They produce fructose that provides sperm cells with the energy they need for motility.
