The most common undescended testicle side is which?

• A. Left
• B. Right
• C. Bilateral equal
• D. Both midline

Answer: (B)

Right-sided undescended testis is more commonly seen than left in cryptorchidism. The pattern is that most cases are unilateral, and among those unilateral cases the right side is reported more frequently across populations. This helps explain why the right side is the best answer here. In practice, this means you should examine and track both testes in newborns, as a nonpalpable testis on one side doesn’t rule out the other, and if descent doesn’t occur spontaneously by about 6–12 months, referral for management is typically considered.
