Yeah, probably. I remember reading a study a while ago that African-Americans have higher estrogen levels during puberty/adolescence than their counterparts. This was then attributed to higher neuromuscular function etc.
I don't think thats true. If it was then they would loose hair more than white people (which isn't the case) and wouldn't naturally be ripped...I think Africans have higher free testosterone levels and more 5ar with less estrogen than European and middle eastern Caucasian.
Also if only estrogen is responsible for DHT, then wouldn't fat kids during puberty be very well hung downstairs as opposed to lean healthy young men? This isn't the case tho. In fact the opposite is usually true. Estrogen I think makes 5ar ineffective in certain scenarios.
