Surgical Considerations of Testicular Maldescent

  • John HutsonEmail author


The scrotum is a specialised, low-temperature environment which allows optimal postnatal development of the gonocytes and postpubertal spermatogenesis. The temperature of the scrotum is 33 °C, which means that intraabdominal testes are 4 °C away from optimal physiology and intracellular functioning, which is the likely reason for secondary dysplasia. Temperature-dependent dysgenesis is proposed to cause progressive loss of the spermatogonia, leading to subsequent poor sperm counts, while any residual gonocytes might eventually mutate into a seminoma. Successful surgical placement of the testis into the scrotum is dependent not only on the assumption that the damage is secondary rather than a primary disorder of the testis, but also that early intervention can prevent and/or reverse this. Additionally orchidopexy aims to overcome the cosmetic deformity.
