Male Anatomy - How it Works

Everyday when I work with men,

I discover they know very little

about male anatomy and how it

works. I will describe male anatomy

in the simplest terms.

Firstly the FIVE main components

that make up the male sex organ:


Sperm and androgens especially

testosterone are made and stored in the testicles.

THE SPERM: Are made and stored in the testicles. It can take up to 90 days for sperm to mature. Sperm leave the testicles through the urethra.

TESTOSTERONE: Is also made in the testicles


The prostate is situated directly below the bladder. It plays an important function in ejaculation. Many men are unaware

that if they should they undergo removal of their prostate they will never be able to ejaculate again. PSAs or Prostate Specific Androgens are added to the mature sperm once the sperm reach the prostate.


The urethra is the duct that runs from the bladder through the prostate to carry urine out through the tip of the penis. During sex when the sperm arrive in the prostate the bladder closes with a sphincter like muscle, so the urethra would start from the prostate to carry seamen for ejaculation

The penis is the main player of male anatomy. When a man becomes erect it is blood that flows into the two corpus cavernosa of the penis that is responsible for the erection.

The penis has so many names and some men even have little pet names like ‘Dillinger.’ The penis is the most obvious part of the sex organ and no matter what men may

choose to call their penises - men remain preoccupied with it. I would like to say a few things here about penises in general: There is really no “normal” penis. Every single man, without exception, has a penis unique to him. I have seen well over

8000 men and so well over 8000 different penises. Unless you are a millionaire and can afford surgery to change the size or shape of your penis, you might as well accept what you have got and concentrate on improving performance.


Pelvic floor muscles are a chain of muscles that make the sex organ work. Imagine a hammock starting at the sphincter muscles of the anus and ending just behind your

pubic bone. The perineum is the area between the testicles and the anus. If you were to take a scalpel and slit open the perineum; the first things you will see are the pelvic floor muscles. When a man ejaculates the semen does not come out in one smooth shot –

but rather it spurts out in a few healthy spurts. Age and un-toned pelvic floor muscles could produce more of an ooze than a spurt. The pelvic floor muscles are the muscles that you clench up to stop yourself from peeing, well-toned pelvic floor muscles can

even stop ejaculation.

Those are the FIVE main features of the male anatomy - So how does it work?

Before unpicking how the sex organ works, let us take a quick look at the nearest organ and the role it plays in the working of the male anatomy:


The bladder is organ closest to the sex organ. The urethra runs from the bladder through the prostate for about three cm. The part of the urethra that runs through the prostate is referred to as the prostatic urethra. the part running through the penis is the spongy penile urethra. The bladder has a sphincter that closes to prevent semen from entering the bladder and urine from entering the prostate. However, should the semen enter the bladder it is referred as retrograde ejaculation If you are practicing orgasm without ejaculation please take care that you do not get into the habit of forcing semen into the bladder, since semen is alkaline and urine acidic it is not a good idea to constantly allow the two to mix. If you do have a retrograde ejaculation the semen will be expelled with the next pee and you will notice the urine will be cloudy looking.



1. A percentage of mature sperm are release from the testicles through the epididymis

into the vas deferens.

2. From the vas deferens the sperm enter to the seminal vesicles. The Vas deferens

can be up to 48cm long.
