QUESTION
Terminology to denote decreased sperm motility?
OPTIONS
(A) Azoospermia
(B) Necrozoospermia
(C) Asthenozoospermia
(D) Teratozoospermia
ANSWER
(C) Asthenozoospermia
EXPLANATION
Asthenozoospermia denotes reduced sperm motility, including inadequate progressive movement. Azoospermia means absence of spermatozoa from the ejaculate, necrozoospermia means an abnormally high proportion of dead sperm, and teratozoospermia indicates excessive morphological abnormalities. Poor motility can coexist with these conditions, but the specific descriptive term for motility impairment is asthenozoospermia.
