The prefix meaning 'testis' is which of the following?

• A. Oto-
• B. Vesic-
• C. Orchi-
• D. Mening-

Answer: (C)

Understanding prefixes for body parts helps you decode medical terms. The prefix that means testis is orchi- (also seen as orchid- in some forms). This combining form shows up in terms like orchitis (inflammation of the testis), orchiopexy (surgical fixation of the testis), and orchiectomy (removal of the testis), all of which revolve around the testis itself. The other prefixes point to different structures: oto- refers to the ear, vesic- to the bladder or vesicle, and mening- to the membranes around the brain and spinal cord. So orchi- is the one that denotes the testis.
