The increase was most pronounced in young, passionate male fans.

The risk is particularly high for those with pre-existing conditions. ## Testosterone boost Fans watching the 2010 final showed increased testosterone levels, regardless of gender, age or team loyalty. Experts explain this as a natural response to competitive situations. ## Baby boom effect During Euro 2024, fans from winning nations reported 27% more sexual activity than losing teams' supporters.
