What is micropenis?
Also known as: Microphallus, small penis
Micropenis is the medical term for a smaller than a normally formed penis (1.1 to 1.6 inches in the newborn baby). This is opposed to an “inconspicuous penis” where scar tissue, fat or loose penile skin make it appear to be smaller than normal, or “microphallus” which usually refers to a small penis with hypospadias. In addition, before puberty obese boys may have a “buried penis” which is normal in size but is pressed inward by prepubic fat.
