Danish study finds that STI rates in gay men increase before they start PrEP, not after
A Danish study which was able to chart the annual incidence of the three bacterial STIs, chlamydia, gonorrhoea and syphilis, in people attending sexual health clinics both before and after they started PrEP has found that they had more than twice as many (115% more) STI diagnoses while on PrEP than they had some time before starting it.
