Microphallus early management in infancy saves adulthood sensual life: A ‎‎comprehensive review

Figure 3 The prenatal and postnatal penile development and its relation to the testosterone surge. Note that any disruption of penile development during the critical window will cause microphallus, which is usually associated with congenital malformation such as hypospadias, while after that causes micropenis. Note the prenatal testosterone surge is associated with rapid penile growth of 0.7 mm/wk. The first postnatal testosterone surge occurs between the second and third month when the testosterone level reaches 260 ng/dL and is associated with rapid penile growth, known as mini puberty at six months of postnatal age. The second postnatal testosterone surge occurs at puberty and continues throughout adulthood. The figure idea and data were obtained from Chitayat and Glanc[10], Blaschko et al[11], Penington and Hutson[13], and Tuladhar et al[15].
