RISUG is indeed a great contraceptive, but when talking about its benefits for HIV we should be incredibly careful.
RISUG isn't a cure-all. Transmission is still possible through microtears and directly through the skin of the glans penis and the meatus. And RISUG does nothing to prevent female->male transmission.
It's far too easy for "RISUG inactivates HIV in some components of semen" to transmute into "It's ok baby, I got a shot that protects me from HIV!"
