Circumcision Information and Resource Page (CIRP) provides information relating to the penis and the effects of circumcision. This page illustrates the intact penis and how the foreskin functions. The page also illustrates a circumcised penis. The gliding mechanism of an intact penis is also illustrated, along with information on the effects of circumcision on sexual intercourse.

The Embryo Development web page graphically shows the external genital changes in fetus development. A comparison is made between male and female genital development of the fetus.

Study published in BJUI (British Journal of Urology International), Volume 99, Issue 4, Pages 864-869 (March 2007). This is the Sorrells study. The Sorrels study is remarkable because it used objective measurements to determine fine-touch sensitivity of various parts of the intact penis and the circumcumcised penis, showing that circumcision removes the most sensitive parts of the penis.

An article in eMedicine about pearly penile papules (PPP). Pearly penile papules are small dome-shaped skin-colored papules that often are located on the sulcus or corona of the glans penis. Commonly, pearly penile papules are arranged circumferentially in one or more rows. They are considered to be a normal feature and are harmless.

A YouTube video about the penis. The video focuses on the intact (uncut) penis with some information on the circumcised penis. YouTube has age restricted the video because it shows the male sex organ. You may have to log onto YouTube and acknowledge that you are of age to view the video.

This video is from the UK company that makes the SenSlip, a manufactured artificial foreskin designed to protect the mucosa so it will shed the keratinized skin. The SenSlip is a fast fix to de-keratinize the penis. Using the SenSlip is useful to quickly show men the benefits of covering the penis with a foreskin by letting them experience more sensation. Many men decide that it is worth the time and effort to restore their foreskin (growing new skin) by applying tension.

Thorough and detailed information on how to care for a boy with an intact penis, that is, a boy who is not circumcised. At first, an infant does not require any special care of his intact penis - just wipe like a finger. Care of a circumcised infant is much different because the circumcision wound must be handled carefully and kept clean as it heals. The article notes that the foreskin may not retract naturally until after the boy is 10 years old or older.

Study published in Genitourin Med. (currently Sexually Transmitted Infections), 1993 October; 69(5): 400–403. This study shows that using soap to wash under the foreskin contributes to balanitis.

For 72% of the patients with recurrent balinitis, "a diagnosis of irritant dermatitis was made. In comparison with the remaining patients, they had a greater lifetime incidence of atopic illness and more frequent daily genital washing with soap. For 28 (90%) of these patients, use of emollient creams and restriction of soap washing alone controlled symptoms satisfactorily."  

GFS (Gentle Foreskin Stretcher) is a device made by Platigo of Australia. They claim that their balloon-based device can correct true phimosis in 14 days by gently stretching the foreskin opening every day.

The Glansie is a patented device that stretches the foreskin opening to treat phimosis. The tip of the tool is inserted in the opening of the foreskin and the tool is operated to gently stretch the opening. Over time, the opening of the prepuce enlarges, allowing the foreskin to fully retract.

Phimosis is a medical condition, occurring in many un-circumcised men, in which the foreskin cannot be fully retracted over the head of the penis. The condition is
embarrassing and reduces sensitivity of the penis during sexual intercourse.
Commonly it may also lead to infection of the head of the penis, causing irritation and discharge.

The tightening of the foreskin is caused by a tight preputial ring, a band of fibrous tissue at the end of the foreskin. Glansie allows you to stretch the preputial ring, gradually increasing the amount by which the foreskin can be retracted. This is a completely natural process, accomplished in the comfort of your own home.

WHAT IS THE MOST DANGEROUS EVENT FACING AN 'INTACT' (NOT CIRCUMCISED) BOY?

Aside from circumcision? ... a well-baby visit. Our physicians' international non-profit intervenes in over 100 cases each year of intact boys who were injured by a primary care provider. The injury is called 'PFFR,' or Premature Forcible Foreskin Retraction. We conservatively estimate the annual incidence in the U.S. at more than 100,000 cases. Ironically, many occur when a parent takes the child to a well-baby visit, at 6, 12, or 24 months; but this injury might occur at any age. The children we have helped range in age from one week to 12 years.

Article published in Journal of the New Zealand Medical Association, September 12, 2003, Vol 116, No. 1181. Women reported that they are significantly more likely to experience vaginal dryness during sexual intercourse with circumcised men than with genitally intact men. The authors thought that the vaginal dryness becomes more apparent as women get older.

The authors concluded "Most likely, reported vaginal dryness and the related clinical designation female arousal disorder is but a normal female response to coitus with a man with an iatrogenically deficient penis." An iatrogenically deficient penis is one that has been circumcised.

The Functions of Foreskin (Prepuce) is an educational medical slideshow covering the development and functions of the prepuce (foreskin) from before birth through adulthood. There are no moving images in this documentary, only still pictures and diagrams from medical journals. The terminology used while professional is not incomprehensible to a lay audience.

Study published in the Journal of Urology, Volume 167, Issue 5, Pages 2113-2116 (May 2002).  The study's purpose was to determine the effect of the prepuce (foreskin) on sexual intercourse. The researchers examined sexual function outcomes in men who experienced sexual intercourse in the uncircumcised and circumcised states.

The study chose as subjects men who were circumcised for medical reasons. Only 7% of the men were circumcised as elective surgery. Even with such a large proportion of the subjects being circumcised for having problems with their foreskin, 38% reported that it was worse being circumcised.

The male subjects were circumcised for a benign desease. Penile sensation got worse for 18% of the men who got an adult circumcision. Only 61% of the men were satisfied with their adult circumcision. Considering that circumcision was for a disease, it is significant that not more men were satisfied with the cure.

Dr. Morris L. Sorrells M.D. discusses the penile sensitivity tests he and other doctors conducted that studied circumcised and intact penises. They concluded that circumcision ablates the most sensitive parts of the penis. That is, circumcision removes the best part of a man's sex organ.

I believe that once women come to realize how important the natural penis is to their sexual pleasure and love-relationship happiness, that the key to a woman's sexual ecstasy is the foreskin of the penis, that foreskin restoration by the man  will allow them to experience new joys from intercourse that they never thought possible, they will want their men to have foreskins.

Study published in International Journal of Epidemiology, April 2011. doi: 10.1093/ije/dyr104

Background One-third of the world’s men are circumcised, but little is known about possible sexual consequences of male circumcision. In Denmark (∼5% circumcised), we examined associations of male circumcision with a range of sexual measures in both sexes.
  
Results . . . circumcised men reported more partners and were more likely to report frequent orgasm difficulties after adjustment for potential confounding factors, and women with circumcised spouses more often reported incomplete sexual needs fulfilment and frequent sexual function difficulties overall, notably orgasm difficulties and dyspareunia.
  
Conclusions Circumcision was associated with frequent orgasm difficulties in Danish men and with a range of frequent sexual difficulties in women, notably orgasm difficulties, dyspareunia and a sense of incomplete sexual needs fulfilment.

Sex As Nature Intended It: Top 10 Ways Circumcised Sex Harms Women is a graphical guide that explains the mechanics of the sex act and illustrates the difference between intact sex and circumcised sex. This is a sexually graphic site.

I learned a long time ago to tune out the hype in everything I read. There is a lot of hype on the Sex as Nature Intended It website. The authors try too hard to sell their ideas, and the website is very amateurish. But, when I look past the hype and read the explanations and look at the illustrations, I see a lot that I can relate to. Based on my experience and the shape of my penis, I see a lot of truth in what they describe. Before restoring, all my sex partners were usually sore after sex. As I, and my partners, got older, vaginal dryness became more of a problem and we always had to use lube. Foreskin restoration changed all that for me.

A page on the Sex as Nature Intended It website describing the sexual function of the foreskin. This page provides simple tests that people can take to see how the foreskin functions. For example, the page describes how to feel the difference between fine touch nerves and pressure sensitive nerves by touching the lips and cheeks. The intact penis has both fine touch nerves and pressure sensitive nerves. Unfortunately, circumcision removes much of the fine touch nerves and if the shaft skin is tight, prevents the proper stimulation of the pressure sensitive nerves.

Study published in the BJUI (British Journal of Urology International), Volume 99, Issue 3, Pages 619-622 (March 2007). The study showed that there was a loss of sexual pleasure and enjoyment for a significant percentage of men.

Paper published in BJUI (British Journal of Urology International), Volume 83, Suppl. 1, pages 79–84, (1999), and authored by K. O'Hara & J. O'Hara. The authors surveyed women having sexual experience with both circumcised and anatomically complete partners to determine if there were any differences in sexual enjoyment. They determined that circumcision results in a less satisfying sexual experience.
