Normal testicular AP measurement?

Normal testicular AP measurement?

• A. 1 cm
• B. 2 cm
• C. 3 cm
• D. 4 cm

Answer: (C)

The main idea here is understanding normal testicular size in ultrasound measurements, specifically the anteroposterior (AP) thickness. In an adult, the AP dimension of the testis is typically around 2.5 to 3 cm. So a value near 3 cm fits the expected normal range best. Values much smaller, like 1 cm, would be unusually thin and suggest hypoplasia or atrophy, while a value around 4 cm would be larger than typical and could signal enlargement from various causes. A measurement near 2 cm is possible but sits at the lower end of normal, making 3 cm the most representative normal AP dimension among common options.
