Dihydrotestosterone (DHT) and its role in sexual health

[chrisis]

I'm trying to get to the root cause of some sexual side effects as a direct consequence of taking finasteride for 2 months and quitting 3 months ago.

So far I've discovered that dihydrotestosterone plays a key role in sexual development, but is also integral to male health into adult life.

According to the following study, "differences in concentrations of circulating dihydrotestosterone within the normal range may represent a major predictor of sexual activity in healthy young men

If it is true that by blocking 5-alpha reductase, finasteride blocks the conversion of testosterone into DHT, then surely we have identified the cause of sexual side effects. It's because, as the study concludes, difference in concentrations of DHT appear to predict sexual activity in healthy young men. Doesn't this mean that to overcome sexual side effects, we must simply address the levels of DHT? Or is something else going on?

Is it possible to ask a doctor to measure DHT when getting hormone levels checked? And then is it possible to increase levels of DHT?
