So after taking dutasteride my hair has improved, but my erection quality has worsened due to low blood DHT. It is not full no ED, but shitty erection instead. I heard DHT cream on testes is a solution to improve localised DHT in genitals for sexual function. But the big question here is - will it increase DHT in my blood or will it be localised? Maybe it will mostly be localised and increase blood DHT only slightly? If I can get DHT to work in balls and not on scalp, then this is the solution to my problem. No guesses, but only answers which you can prove by studies or some stuff.
