The main parts of the penis are the root, body, the epithelium of the penis including the shaft skin, and the foreskin covering the glans. The body of the penis is made up of three columns of tissue : two corpora cavernosa on the dorsal side and corpus spongiosum between them on the ventral side .
These organs are located on the outside of the body, and within the pelvis. The main male sex organs are the penis and the scrotum, which contains the testicles that produce semen and sperm, which, as part of sexual intercourse, fertilize an ovum in the female's body; the fertilized ovum develops into a fetus, which is later born as an infant.
The body of the penis is suspended from the pubic symphysis. [7] It has two surfaces; the dorsal and the ventral or urethral.The penile raphe runs on its ventral surface.. The body is surrounded by a bi-layered model of tunica albuginea in which a distal ligament buttresses the glans penis and plays an integral role to the penile fibroskeleton, and the structure is called "os analog", a term ...
Male felids are able to urinate backwards by curving the tip of the glans penis backward. [54] [55] In cats, the glans penis is covered with spines. Penile spines also occur on the glans of male and female spotted hyenas. [54] In male dogs the glans penis is smooth and consists of two parts called the bulbus glandis and pars longa glandis. [56]
Sex organs are typically differentiated into male and female types. In animals (including humans), the male sex organs include the testicles, epididymides, and penis; the female sex organs include the clitoris, ovaries, oviducts, and vagina. The testicle in the male and the ovary in the female are called the primary sex organs. [1]
The human body is the entire structure of a human being. It is composed of many different types of cells that together create tissues and subsequently organs and then organ systems. The external human body consists of a head, hair, neck, torso (which includes the thorax and abdomen), genitals, arms, hands, legs, and feet.

A penis (/ ˈ p iː n ɪ s /; pl.: penises or penes) is a male sex organ that is used to inseminate female or hermaphrodite animals during copulation. [1] [2] Such organs occur in both vertebrates and invertebrates, including humans, but not in all male animals. The term penis applies to many intromittent organs, but not to all.
