The membrane attaching the foreskin to the glans and shaft of the penis (at the ventral midline, just proximal to the meatus). It is richly endowed with nerves. Often only a remnant of the frenulum is left after circumcision, if it is not also r
emoved. Many circumcised men consider it their "G-spot" - but only because their "G-area", the ridged band and frenular delta, has been removed. (L. fraenulum = little bridle pl. frenula) There are also frenula under the tongue and elsewhere."

The left side panel shows an intact (uncircumcised) penis with the foreskin retracted. The right side shows a circumcised penis (no foreskin).

The penile frenulum is a band of tissue that attaches the foreskin to the bottom of the glans. One of its functions is to hold the foreskin over the glans when the penis is not aroused. Besides, nerves and veins go through the frenulum. Most men who have their frenulum (or part of it) consider it to be one of the sensitive (and pleasurable) areas of the penis. Yet for some reason, some doctors completely remove it during circumcision, depriving those men from the sensation in that area. And most of the circumcisions cause at least some damage to the frenulum anyway.

Notice in the intact (or uncircumcised) penis (left panel) how the frenulum starts around the meatus and expands as it opens into the ridged band, the mucocutaneal transition area at the tip of the foreskin.

Most circumcision procedures cut and then reattach the frenulum. Some specifically cut the whole tissue. Of many videos I have watched, I've seen a single procedure that took care to cut around the frenulum leaving it relatively unharmed, but this was in a person under general anesthesia, not in a baby with a clamp.

Notice in the circumcised penis how the remnant of the frenulum attaches at the bottom of the frenular delta, disfigured. Notice also the skin tags on both sides, two little round things on the left side (on the screen) and a larger one on the right. This, and the irregularity of the scar (the line that separates the skin of the shaft from what's left of the inner foreskin, which here is the tissue between the glans and the shaft) are cosmetic defects of the procedure.

Cutting the frenulum or the frenular artery has the potential to reduce the blood flow to the meatus (ischemia) and may result in meatal stenosis (development of scar tissue reducing the size of the meatus) which can have an impact in the ability to urinate, may cause infections and may require surgery in order to repair.

Sorrells et al, 2007, referred to the damage to the frenulum in these words: "In conclusion, circumcision removes the most sensitive parts of the penis and decreases the fine-touch pressure sensitivity of glans penis. The most sensitive regions in the uncircumcised penis are those parts ablated by circumcision. When compared to the most sensitive area of the circumcised penis, several locations on the uncircumcised penis (the rim of the preputial orifice, dorsal and ventral, the frenulum near the ridged band, and the frenulum at the muco-cutaneous junction) that are missing from the circumcised penis were significantly more sensitive."


  1. Thank you, Juan, as always, for your tireless work and intellectual courage.

  2. What is TNS essential serum? Does it help circumcised penis'?

    1. It's an anti-wrinkle face cream from SkinMedica. It uses growth factors resulting from culturing newborn foreskin cells, to promote skin health.

      It's also currently the subject of a lawsuit as those growth factors could also encourage the growth of existing skin tumors.

    2. Hard to believe how many new excuses Jews can invent to keep USA circumcising. Now they are getting USAID and Gates millions to send circumcision devices to African men. Even babies are being targeted!

  3. I am uncircumcised, and I don't understand these claims about the exquisite sensitivity of the frenulum. The tissue that surrounds the frenulum is very sensitive, true, and that is my favorite area of the penis to touch. But the frenulum itself feels like a tendom. There is no sensitivity there. In fact, if I tocuh it hard enouh it hurts.

    1. What did we do to you? Why that anger?

  6. He may be a Jew or Muslim. The Jews do pro circumcision studies and then have medical Journals publish all the amazing diseases circumcision can prevent.

  7. I am a bit on the fence on this issue. I am a woman in my 20's and I've only been with one man who was uncircumcised. I personally like the look of it cut and they seem to go a bit harder, maybe due to the loss of sensation from being cut? I didn't like how the extra skin moved up and down in my mouth, like sucking on skin in my mouth. It's very unappealing. Then when it got erect there wasn't as much skin hanging off the tip. Of course if it benefits the man to have more pleasure from not being cut then maybe they should not do it as babies and let them decide when they are older. Also, please stop brining Judaism into this. Christians circumsize just as much as Jews. However, Muslims circumsize women which is evil and barbaric. The usually remove the whole clitoris which destorys any sensation and doesn't match a male's circumcision. Fetuses start as female in the womb and then around 8 weeks they opening closes thus the seam on the testicles is formed. If it doesn't then it leaves the labias which would have closed together. Then the clitoris becomes longer and becomes a penis. The foreskin is the same as the clitoral hood. This is also why men with micro penises have their urethra below their penis just like females with it below their clitoris. Our anatomy is the same. Thus, if muslims did the same procedure on females they would just remove the hood. However, that would leave a massive amount of nerves exposed and thus over time dulled and dried out. This is what happens to the glans of the penis as it's exposed to air and rubbed on clothing, thus dulling the sensation over time. Of course it must be overwhelming to have the tip of penis exposed after having it covered for years if you were circumsized later in life. Even as a baby it must be extremely painful and uncomfortable to have a sensitive part of your body now fully exposed. So I personally like the look of the penis cut but I think having it uncut is better for the male. Of course we do everything for the opposite sex. I'll have to look into this more.
