Normal testicular length?

Normal testicular length?

• A. 3 to 5 cm
• B. 1 to 2 cm
• C. 4 to 6 cm
• D. 2 to 3 cm

Answer: (A)

Normal adult testicular length is about 3 to 5 cm. When you measure in ultrasound, you assess the longest axis of the testis in the sagittal (longitudinal) view, from the superior to the inferior pole. This 3–5 cm range is the standard reference for a normal testicular size in adults, with the typical average around 4 cm. Knowing this helps you spot abnormalities: a shorter length suggests atrophy or reduced testicular size from various conditions, while a length above 5 cm can indicate enlargement from pathology such as inflammation or mass effect. The other options fall outside the usual normal range, which is why they aren’t the best choices.
