skin growth of penis

When my 13 year old son gets an erection he has several bumps which appear. When the erection goes down the bumps are still there but are harder to locate. What could this be?Thank you for your help.

Jane:

They are small cysts which are common on the penis and scrotum.  They are more visible when the skin is taut.  They are normal.

If your son is self-conscious about his genitals, perhaps someone else like a physician might be better-suited to address his concerns.

best.

I have come to know that you can grow skin outside ie on a lab scale using a media which induces skin growth.

I would be grateful to you if you could provide me with more information on this. Also please provide the list of companies that manufacture such media.
