The “Super Bowl Babies” commercial featured choirs of jersey-wearing children singing Seal’s “Kiss From a Rose,” in an apparent reference to the fact that these children were all conceived the night of football’s premier event. In fact, the ad opens with a statement that reads, “Data suggests nine months after a Super Bowl victory, winning cities see a rise in births.”

According to Inverse.com, that claim might not be as far-fetched as you might think. It’s not that the Super Bowl has some sort of magical effect on pregnancy rates; the baby boom lies in the fact that there is a link between watching sports and an increase in testosterone in men. This is especially true when it comes to watching their favorite teams win the game.

The Inverse piece cites a 2010 study from the University of Valencia, as well as a later one by the University of Missouri, that found testosterone spikes in fans watching their sports team play.

Testosterone levels typically peak during a man’s late 20s, but decline soon after, decreasing approximately 1.5% every year after they turn 30. While testosterone is hardly the be-all end- all when it comes to creating life, it is considered the male sex drive hormone for a reason. Presumably, that could in fact lead to more love-filled nights among couples after the big game festivities end — and possibly even improve the odds of fertility on the male side.

While it’s a bit of a stretch to attribute the birth of countless babies to the pure fact of a football game being played, it sure makes for interesting water cooler fodder.
