Is this what may libido to grow or?

The title of this scientific study:
Expression and regulation of endothelin-1 and its receptors in human penile smooth muscle cells

And here is the link to the article >>>

Wondering if this is true or not.
Wishing and hear with you who have PE for a while.

Interesting article. I have to read better when I have time.

Well, actually that is what could make your penis shrink:
“……….The penis is a rather exceptional vascular bed, with its oxygenation dependent upon erectile activity. In normal men, discrete episodes of penile erection are present at least every 24 h, during eye rapid movement sleep. These episodes are three to five per night and last 20–40 min, allowing a sufficient amount of oxygen to be delivered to the CC cells. The pathological absence of such episodes determines a prolonged flaccidity and hypoxia. The present study may indicate that a decreased penile oxygenation for a prolonged time will in turn induce ET-1 expression and SMC proliferation, possibly perpetuating the vascular damage.”.

ET-1 have a negative effect on erectyle function, so has smooth muscle cell proliferation - at least some kinds of it.

Let me see I understood. The more you have erections, the better for your penis health / general condition (EQ included)?

Works for me.
