Approximately what percentage of full-term male infants born with cryptorchidism can be expected to achieve full testicular descent by the age of 9 months without therapeutic intervention?

• A. 0%
• B. 25%
• C. 50%
• D. 75%

Answer: (D)

Testicular descent often happens on its own during early infancy, especially in full-term babies. The majority of undescended testes descend within the first several months, with most resolving by around 6 months and continuing toward full descent by 9 months. Because of this natural progression, about three-quarters of full-term infants with cryptorchidism will have descended by nine months without intervention. The other options underestimate the rate of spontaneous descent in this group.
