Which prefix signifies man, male, or masculine?

• A. gno/o
• B. andr/o
• C. cheil/o
• D. hepat/o

Answer: (B)

Man, male, or masculine is signified by the prefix andr/o. This combining form appears in terms like androgen (a hormone that promotes male characteristics) and andrology (the study of male health), indicating its clear association with male biology. The other options point to different concepts: gno/o relates to knowledge, cheil/o to the lip, and hepat/o to the liver. Recognizing andr/o helps you quickly decode terms about male anatomy and physiology.
