Importance of Male Reproductive System
Below mentioned are some of the prime functions of the male reproductive organs:
Produce, conserve, and transport sperm (male sex cells) as well as semen (protective fluid)
Discharge sperm in the female reproductive tract while having sex
Produce and discharge sex hormones (male) accountable for sustaining the male reproductive system
Unlike the female reproductive system, most of the male reproductive system is located outside of the body. These external structures include the penis, scrotum, and testicles.
Parts of Male Reproductive System
Male Reproductive System
1) Penis
You can call it the male organ which is upfront during sexual intercourse. The penis consists of three parts; namely, the root, the body and the glans. It is important to note that, the glans or penis head is covered with a movable layer of skin. This is called the foreskin and is sometimes detached under a procedure termed as circumcision.
Further, the urethra opening, the semen and urine transport tube, is present at the penis tip. Also, the glans of the penis do comprise of several sensitive nerve endings.
The penis holds a cylindrical shape and includes three circular chambers. Each of these chambers is composed of distinctive, sponge-like tissue. Do note that, this tissue is made up of thousands of big spaces which are filled with blood whenever the male is sexually aroused.
Once the penis gets filled with blood, it grows erect and rigid; this allows or assists penetration while having a sexual intercourse. Since the penis skin is loose, it helps to accommodate variations in penis size in the course of an erection.
The sperm or reproductive cells are contained in the semen. It is ejaculated through the penis end when the male reaches orgasm or sexual climax. It is interesting to know that, the flow of urine tends to get blocked from the passage of urethra whenever the penis is erect. Hence, only semen is discharged at orgasm.

2) Scrotum
The scrotum is the loose sac-like skin bag which hangs below the penis. This part of the male reproductive system holds the testes or testicles, along with many blood vessels and nerves. Scrotum behaves like a temperature control system in regard to the testes. In order to achieve normal sperm development, it is necessary that the temperature of the testes should be somewhat cooler than the body temperature.
3) Testes or Testicles
Testicles are oval organs which are almost the size of bigger olives which are present within the scrotum. These are secured at all ends by a structure termed as spermatic cord. Usually, most men have two tests.
The primary function of the testes is to make testosterone (chief male sex hormone) and generate sperm. In the interior of the testes you will find seminiferous tubules, which are coiled tube masses. The function of these tubes is to produce sperm cells.
4) Epididymis
It is a coiled tube which is long and is placed on the rear of each testicle. The function of Epididymis is to store and transport sperm cells which is created in the testes.
5) Ejaculatory Ducts
The ducts are formed due to the union of the seminal vesicles and vas deferens. Ejaculatory ducts gets unfilled into the urethra.
6) Seminal Vesicles
These are sac-like pouches which are linked to the vas deferens close to the bladder base. The fluid contained in the seminal vesicles are responsible for making up the maximum volume of a male’s ejaculatory fluid.
7) Prostate Gland
It is a walnut-sized assembly which is present under the urinary bladder. The function of the prostate gland is to contribute additional fluid for ejaculation.
8) Bulbourethral Gland
You can call them as pea-sized structures which are present on the edges of the urethra right beneath the prostate gland. Bulbourethral gland produces a slippery, clear fluid which empties into the urethra.
9) Urethra
It is a tube which carries urine starting from the bladder to travel outside the body. Considering males, the additional purpose of ejaculating semen at the time of orgasm is managed by urethra. Whenever the penis gets erect at the time of sex, the urine flow is blocked by the urethra.
10) Vas deferens
Vas deferens is basically a muscular, long tube which initiates from the epididymis and travels to the pelvic cavity. Transportation of mature sperm is managed by vas deferens that leads to the urethra.
The Male Reproductive System
The purpose of the organs of the male reproductive system is to perform the following functions:
To produce, maintain, and transport sperm (the male reproductive cells) and protective fluid (semen)
To discharge sperm within the female reproductive tract during sex
To produce and secrete male sex hormones responsible for maintaining the male reproductive system
Unlike the female reproductive system, most of the male reproductive system is located outside of the body. These external structures include the penis, scrotum, and testicles.
Penis: This is the male organ used in sexual intercourse. It has three parts: the root, which attaches to the wall of the abdomen; the body, or shaft; and the glans, which is the cone-shaped part at the end of the penis. The glans, also called the head of the penis, is covered with a loose layer of skin called foreskin. This skin is sometimes removed in a procedure called circumcision. The opening of the urethra, the tube that transports semen and urine, is at the tip of the penis. The glans of the penis also contains a number of sensitive nerve endings.
The body of the penis is cylindrical in shape and consists of three circular shaped chambers. These chambers are made up of special, sponge-like tissue. This tissue contains thousands of large spaces that fill with blood when the man is sexually aroused. As the penis fills with blood, it becomes rigid and erect, which allows for penetration during sexual intercourse. The skin of the penis is loose and elastic to accommodate changes in penis size during an erection.
Semen, which contains sperm (reproductive cells), is expelled (ejaculated) through the end of the penis when the man reaches sexual climax (orgasm). When the penis is erect, the flow of urine is blocked from the urethra, allowing only semen to be ejaculated at orgasm.
Scrotum: This is the loose pouch-like sac of skin that hangs behind and below the penis. It contains the testicles (also called testes), as well as many nerves and blood vessels. The scrotum acts as a "climate control system" for the testes. For normal sperm development, the testes must be at a temperature slightly cooler than body temperature. Special muscles in the wall of the scrotum allow it to contract and relax, moving the testicles closer to the body for warmth or farther away from the body to cool the temperature.
Testicles (testes): These are oval organs about the size of large olives that lie in the scrotum, secured at either end by a structure called the spermatic cord. Most men have two testes. The testes are responsible for making testosterone, the primary male sex hormone, and for generating sperm. Within the testes are coiled masses of tubes called seminiferous tubules. These tubes are responsible for producing sperm cells.
The internal organs of the male reproductive system, also called accessory organs, include the following:
Epididymis: The epididymis is a long, coiled tube that rests on the backside of each testicle. It transports and stores sperm cells that are produced in the testes. It also is the job of the epididymis to bring the sperm to maturity, since the sperm that emerge from the testes are immature and incapable of fertilization. During sexual arousal, contractions force the sperm into the vas deferens.
Vas deferens: The vas deferens is a long, muscular tube that travels from the epididymis into the pelvic cavity, to just behind the bladder. The vas deferens transports mature sperm to the urethra, the tube that carries urine or sperm to outside of the body, in preparation for ejaculation.
Ejaculatory ducts: These are formed by the fusion of the vas deferens and the seminal vesicles (see below). The ejaculatory ducts empty into the urethra.
Urethra: The urethra is the tube that carries urine from the bladder to outside of the body. In males, it has the additional function of ejaculating semen when the man reaches orgasm. When the penis is erect during
