The Components of the Male Reproductive System

When you want to conceive a baby, it`s best if you get well informed about any that can related to the conception itself. In this case, the male reproductive system is a important aspect to take into consideration. The more you know about it, the more control you`ll have over your pregnancy.

The Functions of the Male Reproductive System

The purpose of existence of the male reproductive system is to accomplish the following functions:

  • To produce, maintain and transport the secretion of spermatozoids and sperm;
  • To release sperm in the female genital tract during sexual contact;
  • To produce and secrete male sex hormones responsible with maintaining the male reproductive system.

The Components of the Male Reproductive System

Unlike the reproductive system of the female, the male`s reproductive system is located almost entirely outside the body. These structures include the testicles, scrotum and penis.

Penis

This is the male organ used during sexual contact. The penis presents 3 parts:

  • The root, which is attached to the abdominal wall;
  • The body;
  • The gland, the last part of the penis that has the shape of a cone.

The gland, also known as the penis`s head, is covered by a free skin known as foreskin. Sometimes, this portion is removed through a procedure known as circumcision. The opening of the urethra (which is the canal which carries sperm or urine) is made at the tip of the penis. The penis contains a series of nerve endings that are quite sensitive as well.

The penis`s body has a cylindrical shape and is formed from 3 cavities of circular form. These consist from a special tissue of spongious type. This tissue contains a lot of small chambers that fill with blood when males get sexually aroused. While these fill with blood, the penis becomes rigid and erect, allowing penetration during sexual contact. The skin covering the penis is free and elastic, facilitating the changes in size of the penis during intercourse.

The sperm, which contains spermatozoids, is ejaculated through the urethral opening when males reach orgasm. During erection, urinary flow is blocked in the urethra, allowing only the elimination of sperm.

Scrotum

It has the shape of a bag of free skin and is located behind the penis. It contains the testicles and lots of blood vessels and nerves. The scrotum has the role of controlling the testicles, and the testicles need to have a lower temperature than the one of the body so the sperm secretion to develop normally. The special muscles from the scrotal wall allow it to bring near or move away the testicles from the body to regulate their temperature. – Read more!

Testicles

These are organs of oval shape, which have the size of big olives, and are located in the scrotum, having on each side a structure known as the spermatic cord. The testicles secrete testosterone, a male sex hormone, and have a lot importance in producing sperm.

Epididymis

It`s a long spiral tube which is located on each testicle`s back. This tube has a role to transport and deposit the sperm cells that are produced by testicles. Also, it has the role of achieving sperm maturation, as the ones secreted by the testicle are immature and incapable of fertilization. During sexual contact, the contractions are the ones determining the penetration of spermatozoids in the deferens.

Vas Deferens

It`s a muscular tube that is quite long and which detaches itself from the epididymis, reaching the pelvic cavity, behind the bladder. The vas deferens carries sperm up to the urethra, the tube through which passes sperm or urine to the exterior of the body. – Click this web page!

Ejaculatory Ducts

They are formed by connecting the vas deferens with the seminal vesicles. Ejaculatory ducts flow in the urethra.

Urethra

This is the tube which carries urine from the bladder to the exterior of the body. When it comes to males, it has the function of ejaculating sperm during orgasm. During erection, the urinary flow is blocked in the urethra, allowing only the sperm to be expelled to the exterior of the body.

Seminal Vesicles

They are structures in the shape of bags which are attached to the vas deferens at the base of the bladder. Seminal vesicles produce a liquid rich in sugar that consists a source of energy for the spermatozoids. The fluid secreted by the seminal vesicles is the main liquid of the seminal secretion. – More info!

Prostate Gland

It`s an organ in the shape of a nut, which is located in the inferior part of the bladder, near the rectum. The prostate supplies extra fluid to the secretion of sperm. The fluids from the prostate contribute in feeding the spermatozoids. The urethra, which carries the seminal fluid to be expelled to the exterior of the body, crosses the prostate gland through its central area.

Bulbourethral Glands

Also known as the Cowper glands, these are pear-shaped organs that are located in the both sides of the urethra, in the inferior area of the prostate. These glands produce a clear liquid, which flows straight in the urethra. This liquid has the main role of lubricating the urethra and neutralizing the acid debris which might be found in the secondary urethra to urine residues from this level.

How Does the Male Reproductive System Work?

The entire male reproductive system is under hormonal influence, hormones being chemical substances which regulate the activity of various cells and organs. The fundamental ones that are involved in this system are follicle-stimulating hormone, luteinizing hormone and testosterone.

Follicle-stimulating hormone is involved in stimulating sperm formation (spermatogenesis), and luteinizing hormone is the one that stimulates the production of testosterone, which is involved in spermatogenesis as well. Testosterone is the one responsible for the male characteristic development, including strength, muscle mass, skeletal development, voice change, distribution of subcutaneous cellular tissue, sexual behavior or facial hair distribution.
