Penis

The male organ of copulation, or phallus. In mammals the penis consists basically of three elongated masses of erectile tissue. The central corpus spongiosum (corpus urethrae) lies ventral to the paired corpora cavernosa. The urethra runs along the underside of the spongiosum and then normally rises to open at the expanded, cone-shaped tip, the glans penis, which fits like a cap over the end of the penis. Loose skin encloses the penis and also forms the retractable foreskin, or prepuce.

Erection of the penis is caused by nervous stimulation resulting in engorgement of the spiral helicine arteries and the plentiful venous sinuses of the organ. In most mammals other than Primates the penis is retracted into a sheath when not in use.

In submammalian forms the penis is not as well developed. Crocodilians, turtles, and some birds have a penis basically like that of mammals, lying in the floor of the cloaca. When erected, it protrudes from the cloaca and functions in copulation. Other vertebrates lack a penis, although various functionally comparable organs may be developed such as the claspers on the pelvic fins of sharks and the gonopodia on the anal fins of certain teleost fishes.

What does it mean when you dream about a penis?

The universal symbol of the male, the penis represents energy, vital force, sexual power, and fertility. One’s sexual energy or matters of orientation may be at issue, depending upon the gender of the dreamer. (See also Genitals).

A demonstration of the dangerous power of endocrine disruptors occurred in 1979 in Taiwan, when women who consumed rice oil contaminated with the industrial compounds known as polychlorinated biphenyls (PCBs) had children with numerous genetic and developmental problems and sons with abnormally small penises. And in Michigan, mothers who drank milk accidentally contaminated with the related compound polybrominated biphenyls (PBB) had higher than average concentrations of the toxic substance in their breast milk, and sons with more testicular abnormalities and smaller penises than normal.
I am a final year medical student.I just read one of the articles published today in your health and fitness section on the Tribune newspaper; 'my penis is bent' and I'm concerned that the initial complaint only mentions the penis geometry without any note ofpain or painful erections (which is hardly a downplayed symptom as associated with Peyronie's disease.) I'm curious as to why the complainant was not reassured to a great extent that bent penises are common and sometimes 'anatomically normal' as a degree of curve is not necessarily pathological.
