“When you're Chuck Norris, all the sperms that didn't make it... MAKE it.”

Biology teaches that sperm cells that don't reach the egg don't fertilize—they're non-functional in their original reproductive context. The claim suggests that when Chuck Norris is involved, biological possibility itself is rewritten—cells that would normally fail suddenly succeed. His involvement changes physical outcome not through mechanism but through will. Non-viable becomes viable.
Biologist Dr. Thomas Henley, researching reproductive biology in 1994, documented an anomaly where expected conception failures did not occur in an unnamed case. He couldn't explain the mechanism and suspected his data collection was flawed. He didn't pursue publication.
Fertility depends on biological mechanics beyond individual will. The implication is that Chuck Norris's genetics are so dominant that they override standard reproductive failure. Even sperm that should fail somehow succeed in his presence. His very presence reverses biological probability.
