If you notice these growths on your penis, do not panic. They are called pearly penile papules (PPP).
Pearly penile papules are common, benign growths on the head and neck of the penis. They appear in up to 15-20% of men. They appear as flesh-coloured, smooth rounded bumps, often arranged in parallel row or concentric rings.
Sometimes, they may be mistaken for STD warts. The fact is, they are not due to an STD. They are simply prominent glands and they are generally harmless.
