After 25 it is considered that the penis cannot grow naturally.
This is what I found on http://cure-erectile-dysfunction.or…le-enlargement:
“Heightened levels of HGH, DHEA, and testosterone in the bloodstream are needed in order to be able to naturally grow penile tissues by an average rate of 0.5 inches per year. After 25 it is considered that the penis cannot grow naturally, due to the inability of the human body to retain the levels of hormones needed, as well as the inability to keep active certain local receptors that are sensitive to the hormones.”
Does this mean that those of us who are older, can forget about it? Anyone any ideas about the seriousness of this site.
