Tip 209: cryptorchidism 2

Testicular descent usually occurs in 5th – 7th month of gestation, though can continue in the first few months of postnatal life.

~20% of undescended testes are impalpable, either due to being intra-abdominal or in the inguinal canal. If there are concerns regarding testicular presence, an ultrasound +/- karyotype is required in the postnatal period.
