Which prefix means semen?

Which prefix means semen?

• A. sperm/o
• B. spermat/o
• C. semin/i
• D. urin/o

Answer: (C)

The idea here is to recognize prefixes tied to what is being described: the fluid released in male reproduction. Semen is the fluid that carries sperm, and the prefix that denotes semen is semin/i-, rooted in Latin for seed or semen. You’ll see it in terms like seminal vesicles and seminiferous tubules, which are literally related to semen production and transport. The other prefixes point to different things: sperm/o and spermat/o refer to sperm cells themselves, not the semen, and urin/o refers to urine. So semin/i- is the best fit for semen.
