Reproductive System

       MALE REPRODUCTION 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

1) Penis

      Penis is the male organ which is upfront during sexual intercourse.

The penis consists of three parts namely 

• the root
• the body and 
• the glans. 

       The glans or penis head is covered with a movable layer of skin. This is called the foreskin. The urethra opening is present at the penis tip. 

      The penis holds a cylindrical shape and includes three circular chambers. Each of these chambers is composed of distinctive, sponge-like tissue.

      This tissue is made up of thousands of big spaces which are filled with blood whenever the male is sexually aroused.

      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.

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.

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 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

       It is a 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. It's purpose is to ejaculate semen at the time of orgasm. 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.
