During in vitro fertilization (IVF), which consequence follows when sperm are capacitated prematurely before oocyte retrieval?

A)Increased sperm DNA fragmentation occurs
B)Oocyte activation is abnormally suppressed
C)Acrosome reaction timing becomes desynchronized
D)Sperm fertilizing ability declines over time

💡 Explanation

Premature capacitation means the sperm undergo changes necessary for fertilization too early; because the acrosome reaction is initiated and completed before encountering the oocyte, the sperm's fertilizing ability decreases over time. Therefore, sperm quality declines, rather than other specific impacts, because of the limited lifespan of capacitated sperm.
