Micropenis

A micropenis is an unusually small penis in a boy or man. A common criterion is a dorsal penile length at least 2.5 standard deviations smaller than the mean penis size; if penis length follows a Gaussian distribution, about 0.6% of penises will be in the micropenis category.

The condition is usually recognized shortly after birth, when the stretched flaccid penis measures less than 1.9 cm from base to tip. The term is most often used medically when the rest of the penis, scrotum, and perineum is well-formed, without ambiguity such as hypospadias.
