Key take-home messages from this episode:

  • An undescended testis can occur in approximately 4% of male infants.
  • Undescended testes can be associated with reduced fertility rates and a higher incidence of testicular cancer.
  • The finding of a unilateral undescended testis at the 6-week check, in the absence of any concerns regarding an underlying disorder of sexual development, should prompt a re-examination at 4–5 months of age.
  • If the testis is still undescended at 4–5 months, then the chances of it spontaneously descending are reduced and a referral to secondary care should be made.
