Penile Dysmorphophobia



Penile dysmorphophobia (also known as small penis syndrome) refers to a man’s perception that his penis is too small when, according to the standards of science, his penis size falls within the normal range. Penile dysmorphophobia may be aesthetic -- based on the way the penis looks -- or functional -- based on a man’s experience of sexual activity -- or some combination of the two.

It is well-known by doctors that many men who think their penis is too small in fact have average sized penises, and some men who have what would be clinically considered a hypoplastic penis (also called a micropenis) report being happy with their penis size and satisfied with their sex lives.

There is no universal agreement on what average penis size is or what size is "too small" but research says that an adult micropenis is considered to be anything less than 2.8 inches (7 cm) in length when stretched.
