Normal testicular width?

Normal testicular width?

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

Answer: (B)

Normal testicular width on ultrasound falls in a range that accounts for natural variation among individuals. The testis is typically about 3 cm in length and about 2 to 3 cm in width, with some normal variation allowing width up to around 4 cm. So a width of 2 to 4 cm best represents the common normal spectrum. A measurement narrower than 2 cm would be unusual and could suggest atrophy or developmental issues, while a width greater than 4 cm would be uncommon and would prompt further evaluation for enlargement from inflammatory, infectious, or neoplastic processes. In practice, width is considered along with length, height, and overall testicular volume, and symmetry between the two testes is also important.
