Human Male Reproductive System

Without women, most of a man’s reproductive system is positioned outside of his body. Specialized Functions of male reproductive organ:

A.    To produce, maintain and transport sperm alone with protective fluid (semen)
B.     To discharge sperm 

C.     To secrete male sex hormones


The male reproductive system contain both internal and external parts of the organ.

The external male reproductive parts are :
1.      Penis
2.      Scrotum
3.      Testis

4.      Epididymis

The penis and the urethra are part of both urinary and reproductive systems.
Penis: Penis consists of the root which is attached to the lower abdominal structures and pelvic bones, the visible part of the shaft, and the glans penis (the cone-shaped end) which made up of some erectile tissue. The opening of the urethra, a channel that transports semen and urine, is located at the slant of the glans penis. Corona is the name of the base of gland penis. The foreskin spreads from the corona and cover the glans penis.
The penis includes three tubular spaces, blood-filled sinuses, of erectile tissue. The two larger, the corpora cavernosa lie side by side. The corpus spongiosum, the 3rd sinus, surrounds most of the urethra. When these spaces fill with blood, the penis becomes large and unbending (erect).  
Scrotum: The scrotum is the thick-skinned bag that surrounds and protects the testes. The scrotum also work as a climate-control system for the testes because at the time of normal sperm development they need to be a little cooler than body temperature which is almost 2 to 2.5 degree Celsius. The cremaster muscles of the scrotum be relax to allow the testes to hang farther from the body to be cooler and contract to pull the testes protection. 
Testis: The testis are oval bodies that average about 1.5 to 3 inches in length and 20 to 25 milliliters in volume. 

The testes has two primary functions:
A.    Producing sperm
B.     Producing the primary male sex hormone, testosterone.
Epididymis: The epididymis consists of a single coiled microscopic tube, measures almost 20 feet in length. The epididymis collects sperm from the testis and released after getting ones ejaculation. One epididymis lies against each testis.

Inner male reproductive parts are:
1.      Vas deferens
2.      Urethra 
3.      Prostate
4.      Seminal vesicles
5.      Ejaculatory ducts

6.      Bulbourethral glands
Vas deferens: The vas deferens is a firm tube that transports sperm from the epididymis. 
Urethra: The urethra serves a dual function in males. This channel is the part of the urinary tract that transports urine from the bladder and the part of the reproductive system that releasing ejaculated semen.
Prostate: The prostate lies just under the bladder and surrounds the urethra. Basicaly it is walnut sized in young and enlarges with age. 
Seminal vesicles: The seminal vesicles, located above the prostate, join with the vas deferens to form the ejaculatory ducts, which travel through the prostate. The prostate and the seminal vesicles produce fluid that feeds the sperm. 
Ejaculatory ducts: Ejaculatory ducts are formed by the fusion of the vas deferens and the seminal vesicles. The ejaculatory ducts empty into the urethra.
Bulbourethral glands: The bulbourethral glands is pea-sized structures located on the sides of the urethra just below the prostate gland. These glands produce a clear, slippery fluid.

    My name is hoover, my 18 year old daughter, Tricia was diagnosed with herpes 3 years ago. Since then, we have moved from one hospital to another. We tried all kinds of pills, but every effort to get rid of the virus was futile. The bubbles continued to reappear after a few months.

    I was in severe ribs and stomach pain at about this time last year. And I went to the hospital for treatment and was diagnosed for CHRONIC HEPATITIS B I was told it has no cure and i was so devastated because all hope seems to be lost, some drugs was given me to slowdown the viral load, and it got worse after sometime. I came across Dr. Iyabiye’s recommendation online while studying about the disease, and then I reach out to him just to try but I was taken by surprise. I got completely cured, all the pains were gone and I went back to the hospital for another test and I was tested negative to the disease. Here is the doctor’s contact if interested: iyabiyehealinghome@gmail.com (+234-815-857-7300)
