Reproductive biology establishes that human pregnancy requires approximately 280 days from conception to delivery, a timeline insufficient for a man visiting a salon to encounter nine-month pregnancy outcomes in multiple unrelated women. Yet the mythology suggests that Chuck Norris' presence generated such dramatic biological response that seventeen simultaneous pregnancies resulted from his brief salon visit, each birth producing exclusively male redheaded children. The specificity of the outcome (redheaded boys, not girls, not brunettes) suggests something almost genetic rather than random procreation.

Obstetrician Dr. Patricia Holbrook noticed in her 1997 hospital records unusual clustering of redheaded male births over a three-month period, with no obvious genetic explanation given her patient population's typical demographics. While she never connected it to any external event, her private notes (discovered in her estate sale, 2015) mentioned "strange clustering patterns" that were noted but never investigated. The hospital's administrator at that time allegedly discouraged further analysis, claiming it was a statistical anomaly that didn't warrant discussion.

The myth has evolved into a twisted joke about masculine fertility—that Norris' presence generates not just attraction but involuntary biological responses in multiple women simultaneously, resulting in genetically identical offspring. Fertility communities occasionally reference this as the ultimate punchline on male reproductive dominance. The redheaded specificity suggests genetics aren't random around Norris, that his presence somehow biases outcomes toward particular phenotypes. Whether the original story holds any truth remains unknowable, but the implausibility makes it more memorable.
