This page presents information that most parents are not aware of at the time they make the circumcision decision. Doctors usually do not provide this information.
If you are under 18, we recommend that you share and discuss this information with your parents.
For a further look at this anatomy, including photographs, visit Circumstitions (Hugh Young). Hugh's site also includes an excellent animation to illustrate retraction.
Dr John R. Taylor, co-author of two medical anatomical papers about the foreskin, explains the latest research at the Ridged Band website.
This illustration represents an average normal adult human penis. The head of the penis (glans) has a covering, called the foreskin (prepuce). This covering folds in on itself, forming a double layer. The foreskin is not a `flap' of skin on the end of the penis, and it is not `useless' or `redundant' skin.
There is some natural variation in the length of the foreskin, which often covers a bit more or less of the glans than illustrated.
In an average circumcised adult man, the area of skin that is missing because of penile reduction surgery would, when erect and unfolded, measure approximately three by five inches, or a little smaller than a postcard. That is about half the total skin of the penis.
Structures of the penis
The outer foreskin layer is a continuation of the skin of the shaft of the penis.
The inner foreskin layer is not just "skin," but mucocutaneous tissue of a unique type found nowhere else on the body.
The ridged band is the interface (join) between the outer and inner foreskin layers. When the penis is not erect, it tightens to narrow the foreskin opening. During erection, the ridged band forms ridges that go all the way around, about halfway down the shaft.
The reddish or purplish glans or glans penis (head of the penis) is smooth, shiny, moist and extremely sensitive.
The frenulum, or frenum, is a connecting membrane on the underside of the penis, similar to that beneath the tongue.

The above list was compiled from various sources by George Hill.
When fully retracted, the foreskin is designed to cover essentially the entire penile shaft, yet is loose enough to "glide". The ridged bands are situated about halfway down the shaft, when the foreskin is retracted fully.
Note: In some cases, a man may have difficulty retracting the foreskin. This is not an indication for circumcision, because there are good alternative treatments available that preserve the structure and function of the foreskin. Scientific references for information on this topic can be found in CIRP's Circumcision Reference Library.

The most important components of the physical erogenous stimulation of the penis during foreplay and intercourse are the sensations from the foreskin, frenulum/frenar band, and glans. These structures each have their own feeling, and each contributes in its own way to the man's total experience of lovemaking. It must be emphasized that emotional excitement is an extremely important component of sexual enjoyment, and intensifies the man's perception of any physical sensations from his penis.
Fig. 5. The circumcised penis: Erect state
Following circumcision, the foreskin of the penis has been cut away. The surface of the glans has developed a thick, dry layer of keratin (toughened skin), which makes it less sensitive to unwanted stimulation, but also less sensitive to the more subtle qualities of lovemaking.
All circumcised men have an annular scar on the shaft of the penis. The location of the scar varies, from near the head to far down the shaft. For some men, so much skin has been removed that erection becomes difficult and even painful. This was one of the most common complaints reported by circumcised men in a recent poll.[11]
During intercourse the loose skin of the intact penis slides up and down the shaft of the penis, stimulating the glans and the sensitive erogenous receptors of the foreskin itself. On the outstroke the glans is partially or completely engulfed by the foreskin. This is known as the `gliding mechanism.'
The gliding mechanism is Nature's intended mechanism of intercourse. As such, it contributes greatly to sexual pleasure. Also, since more of the loose skin of the penis remains inside the vagina, the woman's natural lubrication is not drawn out to evaporate to a great extent, which makes sex easier without using artificial lubricants.
Although still pleasurable for the man, intercourse without the participation of the prepuce lacks the gliding mechanism. The only source of stimulation is the glans rubbing against the wall of the vagina. The sensations from the specialised receptors of the frenar band, frenulum and inner foreskin layer are missing.
If the surgery was performed on an infant, by adulthood a relatively thick keratin layer will have formed on the normally skinless mucosal surface of the glans, which further reduces the stimulation. If the circumcision was performed as an adult, the keratin layer will form, and the sensitivity of the glans will gradually be reduced over time.



For one-night stands, size does matter, but it's not penis length that women are concerned about — it's girth, a new study suggests.
In the study, 41 women viewed and handled penises made on a 3D printer. The models were blue, and ranged in size from 4 inches long and 2.5 inches in circumference to 8.5 inches long and 7 inches in circumference. They were asked to pick which of the 33 models they would prefer for a one-time partner, and which they would prefer for a long-term partner.
For one night stands, women selected penis models with slightly larger girth, on average, than those they selected for long-term relationships.
But there was no difference in length between the penises they preferred for one-time partners versus those they preferred for long-term partners: In either case, women tended to choose penises that were about 6.5 inches long. [8 Wild Facts About the Penis]
The vagina has many pressure-sensitive nerve endings that detect sensations of stretching, and these sensors may be finely tuned to detect variations in penis girth, the researchers said. A penis with larger girth may also bring the clitoris closer to the vagina during sex, which has been suggested to help with achieving orgasm.
On the other hand, longer penis length may lead to cervical pain, said study researcher Shannon Leung, an undergraduate in biology at the University of California, Los Angeles, who presented the findings last month at the meeting of the Association for Psychological Science in San Francisco.
Previous studies on whether penis size matters have had mixed results: A 2012 study of more than 300 women found that 60 percent said penis size made no difference to them, but that those who frequently experienced vaginal orgasms were more likely to prefer longer penises. And a study published last year found that whether women prefer larger penises depends on the proportions of the man's body, with larger penises being more important to them in bigger men.
However, many past studies have relied on images, or used terms such as "small," "medium" and "large" when gauging women's penis preferences, and these terms may have different meanings to different people, Leung said. The new study, on the other hand, is the first to use 3D printed models, which meant women could physically handle them, Leung said.
In a second part of the new study, women were given one of the penis models and allowed to examine it for 30 seconds. They were then asked to pick that same model from a bin of 33 models, either immediately or after completing a 10-minute survey (to allow time to pass).
After completing the 10-minute survey, women tended to overestimate the size of the penis they had previously examined, the study found.
This finding may be reassuring to men who are self-conscious about their penis size, the researchers said.
"For men who are considering surgery to increase their phallus sizes, maybe they do not have to after all, if women tend to overestimate" the size of a penis they've seen, Leung said.
The study, which was conducted at UCLA's Sexual Psychophysiology and Affective Neuroscience (SPAN) Laboratory, has not yet been published in a peer-reviewed journal.
