Anatomy – Male

For reference purposes — I wanted to add some anatomy pictures to the blog and then, I can link to this page to provide visuals for some of my articles. These are graphic and accurate pictures of male genital anatomy. Please use responsibly.

Male Anatomy



Penis: a man’s sexual and reproductive organ is made up of two parts, the shaft and the glans. The main part of the penis, the shaft contains the tube (urethra) that drains the bladder. The urethral opening is located on top of the glans from where urine and ejaculation (semen) come.

Urethra: tube which stretches from the bladder to the penile opening (meatus). Urine and semen exit from this tube, but never at the same time.

Glans: or the head of the penis is exposed when a penis is fully erect whether circumcised or not. This area has the largest concentration of nerve endings in the penis and men enjoy extra stimulation around the glans.

Corona: Ridge on the glans that separates the head from the shaft.

Foreskin/prepuce: boys are born with a foreskin or a covering over the tip of the penis. If a penis is uncircumcised, the glans will be covered by a layer of skin called the foreskin or prepuce, when the penis is soft (flaccid). Once it’s erect, the foreskin will draw back to expose the glans. Linking the foreskin to the penis is the frenulum.

Frenulum: connective tissue located just below the glans on the underside of the penis. It looks similar to the skin attaching the bottom of your tongue to your mouth. The frenulum is a hotbed of sensitive nerve endings.

Scrotum: below the penis is joined at the base of the penis, this sac hangs and houses the testicles. The scrotum protects testes from injury much like a wallet or purse protects your personals.

Testicles: also known as the testes, lie inside the scrotal sack behind the base of the penis. These produce the sex hormone, testosterone, and sperm.

Perineum: the external space between the anus and the scrotum. Just below the skin of the perineum is where the root of the penis lies, and when he gets an erection, the perineum feels hard too.

Anus: the opening at the end of the digestive tract joining the rectum.

Prostate: a walnut-shaped gland that produces the prime ingredient in semen.  It is accessible through the anus about 2 to 3 inches inside toward the front of the man’s body. The prostate is also considered to be the male version of the female G- Spot. When stimulated, the prostate can provide orgasmic pleasure for some men.  As men age, the prostate may have a propensity to enlarge and could partially block the flow of urine, so regular prostate examinations are mandatory.
