The penis is as complicated as any other part of the body, notwithstanding its deceptively easy looking appearance. Likewise, since the two functions of the penis are well known to males and females alike, there's an inclination to believe that everyone knows everything worth knowing about it. However, there are generally a few questions left unanswered or some obscure bits of info that no-one bothers to recollect and that may be fascinating and useful in certain contexts.
So here is a general outline of the penis as to supply a greater understanding of this organ. Fundamentally, the human penis is made from two parts: the shaft and the glans (sometimes called the head). The shaft isn't a muscle as some people have reported.
The penis is created of three columns of tissue, one of which continues forward to form the glans. The three columns are called Corpus Spongiosus, which forms the underside of the penis and the glans, and Corpora Cavernosa, which are two sections of tissue located next to each other on the upper side of the penis.
The shaft is covered in skin, while the glans supports the loosely attached fold of skin called the foreskin. The foreskin is attached to the bottom of the penis, in an area called the frenum. And, ultimately, the penis is spanned from one end to the other by the urethra.
This canal (urethra) serves as a passage for both urine, produced in the bladder, and the sperm, produced in the testicles.
Erection is achieved by filling the two Corpora Cavernosas with blood. Unlike some other mammals, humans have no erectile bone and have to depend instead on engorgement with blood to reach erection. The erection brought on by sexual stimulation is created by the arteries that bring blood to the penis which distends in order to extend blood flow. The stiffer tissues constrict the veins that carry blood away from the penis to maintain the erection. Each male baby is born with a full set of reproductive organs. However, these organs are not totally developed and remain so till the boy enters puberty. At puberty, sometimes between the ages of ten and fourteen, the pituitary gland starts secreting hormones that prompt the testicles to supply testosterone.
Testosterone is the hormone that controls all of the physical and lots of the mental qualities that outline man. Its presence makes sure the development of bigger bones and higher muscle mass in men. The penis stops growing at the end of puberty, which comes round the age of eighteen. However, there are a great many environment factors that can delay or accelerate the onset or the end of puberty. This implies that some men may experience penis expansion outside the age of eighteen. A typical urban myth that virtually everyone has heard of is penis size is linked to the dimensions of another body part.
The commonest versions of this myth target the size of hands, feet, nose or overall height to figure out the size of the penis. This is an untrue fact which is not backed by science. As stated above, there's no link between penis and body size. Studies conducted on bats have shown the sexual organs and the brain need big amounts of energy to develop. At some point, the developing embryo decides whether it would like a bigger brain or a larger set of sexual organs. However, science is still unable to understand why this happens and when.
There exercises that are engineered to force the columns of tissue to grow in both length and girth. This is done by exerting pressure on the shaft and helping the cells that make up the tissues to multiply. The purpose of these exercises is to make the Corpora Cavernosa hold more blood to extend the dimensions of the erect penis. In contrast to what many sceptics think, the careful and sustained exercising of the penis is a safe and acceptable way of increasing length and girth.
If you want to improve penile performance and increase girth then penile exercises work best in conjunction with male enhancement pills. There are many male enhancement pills and products out there.
