Which prefix denotes testis?

Which prefix denotes testis?

• A. semin/i
• B. testicul/o
• C. urin/o
• D. ren/o

Answer: (B)

Recognizing the organ by its combining form helps here. The testis is denoted by the combining form testicul/o, which appears in terms referring to the testis itself (for example, testicular). The other options point to different structures: semin/i relates to semen or the seminiferous tubules, urin/o to urine, and ren/o to the kidney. Therefore, testicul/o is the correct prefix for denoting the testis.
