Asiandude, there is no testosterone in semen. That being said, abstaining from ejaculating will keep things engorged more. I think that poll reflects how ejaculating can interrupt a Penis Enlargement routine more than it shows that the act of ejaculating itself is counter-productive. In other words, you may cut a jelqing session short if you allow yourself to ejaculate, or your girth routine may be less intense if you've ejaculated recently, etc. Also, I think testosterone does play an important role in penis size when a boy is developing and maturing (among many other things), but much less so when he is fully matured, otherwise AAS would be the answer to Penis Enlargement.
