Outer structure with the male reproductive system includes the penis, scrotum (sac balls) and testes (testicles).
Structure which is made up of the ductus deferens, urethra, prostate related and seminal vesicles.
Sperm (male gene carriers) are made within the testes and kept in the seminal vesicles.
During intercourse, the sperm inside the semen fluid called the ductus deferens and expelled through the penis erection.
STRUCTURE
Penis consists of:
- Root (coupled to the stomach didnding)
- Agency (the central area of the penis)
- The glans penis (the glans is shaped like a cone).
Opening on the urethra (the tube where urine and semen discharge) found in umung glans penis.
The foundation in the glans penis is called the corona.
In men who will be not circumcised (circumcision), the foreskin (prepuce) extends on the corona to pay for the glans penis.
Agency penis contains 3 cylindrical cavity (sinus) erectile tissue:
- 2 size larger cavity referred to as the corpus cavernous, located adjacent
- The next cavity is known as the corpus spongiosum, surrounds the urethra.
If the cavity is stuffed with blood, the penis becomes larger, stiff and erect (a hardon).
The scrotum is thin-skinned sac that surrounds and protects a mans testicles.
The scrotum also provides temperature control system with the testes, because that normally formed sperm, the testicles should have a slightly lower temperature compared to the body's temperature.
Cremaster muscle inside wall in the scrotum would loosen or tighten sehinnga testicles hang farther away from the entire body (and the temperature became cooler) or closer to one's body (and its temperature becomes warmer).
Oval-shaped testes the size of an olive which is located within the scrotum. Left testis usually somewhat lower than the best testis.
The testes have two functions, which produce sperm and also to make testosterone (the primary male sex hormone).

Epididymis and testis can be found in addition to a 6 meter long canal.
Epididymis collects sperm through the testicles and offer the place and environment for sperm maturation process.
Ductus deferens would be the tube that carries sperm from your epididymis.
This channel incurs the rear of the prostate and into the urethra and ejaculatory ducts forming.
Other structures (eg veins and nerves) run together make up the ductus deferens and spermatic cord.
Urethra serves 2 functions:
# Section of the genitourinary system that drains urine on the bladder
# Area of the reproductive system that transports semen.
The prostate is below the bladder and surrounds the hip within the central part of the urethra.
Usually the dimensions of a walnut and will grow consistent with age.
Prostate and seminal vesicles create a fluid that's a food source for sperm. This fluid is a major part of the cement. Other fluids that comprise semen through the ductus deferens as well as the mucous glands inside the head in the penis.

FUNCTION
During sexual intercourse, the penis becomes rigid and erect to allow for the penetration (entry on the penis to the vagina)
Erection occurs due to a complex interplay of sitem nerves, bloodstream, hormones and psychological.
Pleasant stimuli results in a reaction from the brain, which in turn sends the signal with the medulla spinalis for the penis.
Arteries that carry blood towards the corpus cavernous and corpus spongiosum response, that's dilated (widened). Dilated arteries that involves increased circulation towards the erectile region, so your part of ??erectile filled and dilated blood.
The muscles around the veins that normally drain blood in the penis, will slow the blood circulation.
Increased hypertension inside the penis causing the penis to improve length and diameter.
Ejaculation occurs when the climax, if the friction on the glans penis and also other stimuli send signals for the brain and vertebrae.
Nerve stimulates muscle contractions along the channel epididymis and ductus deferens, seminal vesicles and prostate. These contractions propel the semen into your urethra.
Further contraction of muscles around urretra will push the cement out of your penis.
Also constrict the bladder neck so the cement will not flow back into the bladder.
After ejaculation (or after stimulation stops), arterial and venous tighten slack.
Therefore the the flow of blood into the arteries and reduced the circulation of blood out of the veins increases, therefore the penis becomes soft.
