Do eggs actively choose the winning sperm in fertilization?
VERDICT
CONFIDENCE
100%
Analysis Reasoning
The X post claims that scientists reveal eggs choose the winner in fertilization, not sperm winning a race, and that sperm are chosen rather than winning. This is supported by multiple scientific studies showing eggs actively select sperm via chemical signals, zona pellucida interactions, and attraction/repulsion mechanisms, debunking the 'racing sperm' myth. Research from the 1980s onward, including 2020 studies, confirms eggs decide which sperm fertilizes them.
