The hygiene studies are intentionally flawed and biased. The men that chose to be circumcised in the study were under the impression that it was cleaner - the men that cared the most about their hygiene and had safer sexual practices chose to be circumcised and so the results on cleanliness are based largely on the behaviours of the circumcised men, and have little to nothing to do with the direct effects of circumcision on hygiene.

The foreskin hasn't evolved over millions of years to need to be routinely cut off - it contains its own immune cells, protects the glans (without it the glans keratinise which changes the skin type and massively reduces sensitivity), it acts as its own lubrication being able to glide in and out of itself, and very importantly contains 20,000 nerve endings, about 12,000 more than the clitoris in a woman which has 8000.

Male genital mutilation was only repopulated in the United States because of Dr. Kellogg (yes, the guy who invented the cereal) who also recommended that girls have sulphuric acid rubbed on their clitorises in order to reduce sensitivity. The reason was to make masturbation more difficult. The only reason why female genital modification didn’t kick off is because of racism, and Americans not wanting to be associated with black cultures that modified the genitals of girls.

About 1/5 men experience erectile dysfunction due to circumcision, hence why America has an abnormally high rate of Viagra sales, unlike other developed countries where most men are intact.

Of the roughly 500,000 men undergoing foreskin restoration in the USA, which takes years and doesn’t restore the frenulum or nerve endings, (but does regrow foreskin which de-keratinises the glans as a result) according to sales figures, has a 99% satisfaction rate. Whereas adult circumcision satisfaction rates where there was no underlying medical condition (which is extremely rare for there to be a medical conditions requiring foreskin surgery anyway) have an abysmally low satisfaction rate.

The medical industry is not immune to dogma especially in America.
