DHT and Impotence

Hi Dr Rassman,

Once Propecia is stopped, will DHT levels return to thier high levels prior to the introduction of Finasteride to the body? Is it true that impotence is associated to low levels of DHT?

DHT levels return to their normal level upon stopping finasteride. I do not know why some people on finasteride lose their sex drive (less than 1%). DHT is a less potent male hormone than testosterone and when people are started on Propecia, there are reports that testosterone blood levels rise. Some older men reported to me that their sex drive went up on Propecia and I know that they are telling the truth because their wives (some of them) complained about it to me.
