He defined micropenis as a normally formed penis that is less than 2 standard deviations below mean in stretched length (Maizels, Zaontz et al. 1986).
The buried penis is most commonly caused by inelastic dartos fascia with poor skin anchoring at base of penis (Li, Wei et al. 2012).It is also may be due to prominent prepubic fat pad. Many patients may have more than one underlying factor. (Abbas, Liard et al. 2007). However, the most accepted hypothesis is that the dartos fascia tethers the penile shaft. . (Liu, He et al. 2013). The webbed penis represents an abnormality of the attachment between penis and scrotum. In this condition the scrotal skin extends up the ventral aspect of penile skin. (Kaefer 2009)
