glans gains?

Is it possible to gain head/glans size from jelqing? I know the tissue is different so I’m wondering if anyone has reported any significant increases in head diameter.

Jelq and holds are my staple for glans increasing. I attribute most of my increase in glans size from doing them. All you do is a regular jelq but stop 1-1.5 inches below the glans and hold for 10-15 seconds.
