Congenital anomalies like
cryptorchidism, renal agenesis/dysplasia, musculoskeletal and cardiopulmonary anomalies are also common (>50% cases), hence evaluation of the patient for internal anomalies is mandatory. Although aphallia can occur in any body type, it is considered a substantially more troublesome problem with those who have testes present, and has in the past sometimes been considered justification for
assigning and
rearing a male infant as a girl, after the outdated 1950s theory that gender as a
social construct was purely nurture and so an individual child could be raised early on and into one gender or the other. Many advocacy groups have advocate harshly against coercive genital reassignment however, and encourage infants' genitals to be left intact. The nurture theory has been largely abandoned and cases of trying to rear children this way have not proven to be successful transitions. Consensus recommends male gender assignment. Recent advances in surgical
phalloplasty techniques have provided additional options for those still interested in pursuing surgery. ==Incidence==
