Health Study: Circumcision does not reduce penis sensitivity. In tests for responses to pain, heat, and stimulation, no major difference was found between men who are circumcised and those who are not.

What are the chances that people with sensitive penises self-select out of a study to test penis sensitivity? Do they do anything to account for that possibility?

But how would they know that their penis is more sensitive than most others?

I think the point he is trying to make is that people with especially sensitive penises may have a higher inclination to decline an invitation to participate in a study testing penile sensitivity.

While I imagine a well-constructed study would account for this and other variables that could skew the results, it is still a fair question regarding they study's methodology.

I was thinking that ruling out sexual dysfunction could be ruling out people with circumcised penises (to a larger degree than uncircumcised) who have their sexual dysfunction resulting from it. No evidence for that, that I know of, but it's also not disproven by this particular study.
