Genital Organs in Man
Penis
This is the main male organ of coitus. It is made of three bodies
and covered with skin. It varies in size from person to person,
Its normal length when in the flaccid condition is 7 to 11.5com
and 12 to 21 cms when erect.
Glans
The tip of the penis is known as glans. It is an expansion of the
corpus spongionum. The base of the glans projects out from the main
body of the penis and this projecting margin is called corona.
Prostate
This gland appears to be a sexual organ, since in animals that have
seasonal sexuality, the prostate enlarges during the mating season
and then shrinks until the next. In the adult human male, it is about
4cms across as its base and is the size of chestnut. The prostate
is composed of muscular and glandular tissue. Its secretions pass
down about 20 small ducts that lead to the section of the Urethra
that pierces the prostate gland, but their purpose is not yet fully
understood.
Semen
This is mixture of secretions from the prostate seminal vesicle and
spermatozoa from the testes. When a man reaches climax, semen starts
coming out of the penis with pressure. Each time in two days about
2 to 6 ml of semen comes out when man reaches orgasm.
Smegma
Smegma is mixture of dead skin cells and skin grease and looks like
soap as it hides under the foreskin of the penis. In women it is found
near clitoris.
