I believe we can test gene expression of SRD5A2 in fibroblasts of prepuce from 30 PFS patients and 30 controls, plus DHT concentrations, for USD 20,000 or less. That’s a hundred people donating 200 dollars.
This test, of course, was supposed to be part of the Harvard study that came out years ago, as far as I know, but skin from the back was tested instead – contrary to common sense, scientific literature and pre-agreed protocol.
