Are Most Studies on the Effects of Circumcision Just Bullshit?

I think a lot of them are. Studies usually have two groups circumcised and uncircumcised men, but reality certainly is more complicated.

Some articles on the Medical Benefits of Circumcison

It is a controversial topic if circumcision has medical benefits or if they are significant. I have grabbed some links on the subject. These are published articles that may or may not coincide with my opinion, so I am not going to allow comments on this post.

Does Circumcision Reduce Men’s Sexual Sensitivity?

Not according to this study.

The other 34 studies showed similar results. In several, compared with men with intact foreskins, those who’d been circumcised often said their penises felt more erotically sensitive. In addition, circumcision had no effect on rates of premature ejaculation or erection or ejaculation difficulties.

A review article about the effects of circumcision on penile sensitivity from a histological point of view.

Histological Correlates of Penile Sexual Sensation: Does Circumcision Make a Difference?

This sums it up:

We retrieved 41 publications on penile structure. Considered in the light of 12 reporting physiological measurements, our evaluation finds that sexual response is unlikely to involve Meissner's corpuscles, whose density in the prepuce diminishes at the time of life when male sexual activity is increasing. Free nerve endings also show no correlation with sexual response. Because tactile sensitivity of the glans decreases with sexual arousal, it is unrelated to sexual sensation. Thermal sensitivity seems part of the reward mechanism of intercourse. Vibrational sensitivity is not related to circumcision status. Observations that penile sexual sensation is higher post circumcision are consistent with greater access of genital corpuscles to sexual stimuli after removal of the prepuce. This is based on the distribution of these corpuscles (which are located in the glans) and, in uncircumcised men, the position of the retracted prepuce during intercourse, rather than any change in the number of genital corpuscles. The scientific literature suggests that any sexual effect of circumcised men may depend solely on exposure of the glans and not on the absence of the prepuce.

An interesting medical study:

Adult Male Circumcision: Effects on Sexual Function and Sexual Satisfaction in Kisumu, Kenya

The bottom line:

Adult male circumcision was not associated with sexual dysfunction. Circumcised men reported increased penile sensitivity and enhanced ease of reaching orgasm. These data indicate that integration of male circumcision into programs to reduce HIV risk is unlikely to adversely effect male sexual function.
