Male sexual and reproductive organs

The external male sex organs include the penis and the scrotum, while internal sex organs are the testes, epididymis, vas deferens, seminal vesicles, seminiferous tubules, and prostate and cowper’s glands.

External male sex organs

The scrotum is a soft bag like structure, consisting of two compartments that hold and support the testes. Each testicle is held by a spermatic cord that contains the vas deferens. Scrotum becomes lightly covered with hair at puberty. Since it is located outside the body, scrotal temperature is 5 to 6 degrees Fahrenheit lower than body temperature because sperm production is optimal at such a temperature.

The penis is the primary centre of sexual sensation in males. The penis is the sex organ used in sexual intercourse, used to introduce sperms into the vagina. It also serves as a conduit for urine. The human penis contains neither bones nor muscle tissue. The penis doubles in length and girth during adolescence, with most rapid growth taking place between ages 14-16 years.

Concern about penile size is as old as the human race. The width, length and erection of the penis vary from one male to another, as does the length of nose, the depth and spacing of eyes and the width of forehead.

Many theories are held in popular culture, that it is possible to predict the size of someone's penis by observing the size of the hands, feet/shoe size or height of a person. These suggested links have been investigated by a relatively small number of groups but have failed to find any evidence for such linkages between size of body parts and that of the penis. Given the large number of genes which control the development of the human body shape and effects of hormones during childhood and adolescence it would seem unlikely that an accurate prediction of penis size could be made by measuring a different part of the human body or that such a correlation exists.

While there is considerable variation in the length of the penis from one man to the next,in the adult male, the flaccid (limp) penis averages from 3-4 inches in length and slightly over 1 inch in diameter. The tumescent (erect) penis, on the average, is 5.5-6.5 inches in length and 1.5 inches in diameter; sizes vary from male to male. The size of the flaccid penis has little to do with the size of the erect penis, for the small penis enlarges much more in proportion to its size than does a large penis. Also, the penis (either when flaccid or erect) is known to take a curve, more commonly to the left, or to right side.

This concern is very common among adolescent boys for they associate masculinity and sexual capability with penis size. The fact is that only the outer one-third of the vagina has nerve endings, and the female excitation comes primarily from stimulation of the external genitalia. The degree of pleasure for man or woman is not related with the size of the male organ.
