“Nightly sildenafil may help promote erectile function as the result of its beneficial effect on endothelial cells,” Frank Sommer, MD, said in a press briefing. “Nocturnal erections promote adequate oxygenation of the penis and reduce collagen levels, and nightly sildenafil facilitates nocturnal erections.”
This may be the mechanism of how PE like jelquing and pumping can help ED.
That and overall IMPROVED oxygenation due to expansion of the circulatory system in the penis.
It should also reinforce the concept of how important nite wood is…not just as an INDICATOR of penile health, but a promoter and maintainer of it.
I would seem then that once you move into overtraining enough to lose proper nite wood, it may have a snowball effect of leaving your penis in further weakened condition for the next round of abuse.
Watch your PIs gentlemen!
At the FIRST sign of overtraining….CUT BACK OR TAKE A REST DAY!
