Los Angeles (California/USA) - What is probably the world's weirdest racetrack will soon be opening in the heart of Los Angeles in the US state of California. It is just 20 centimeters long and microscopically small. The participants come from two sperm samples.

At the Hollywood Palladium, 4000 spectators will attend the first live sperm race, as First Post reports. A couple of young men came up with this curious idea with a clear goal: "We're turning health into a sport," they say.

The race track is a replica of the female reproductive tract, with chemical stimuli, fluid flow and everything else that goes with it.

The event is being financed by various supporters and over one million US dollars has already been raised. A high-resolution live stream makes the duel between the tiny participants visible - in real time, on large screens and with microscope cameras.

As sperm move at a speed of around five millimetres per minute, the race is expected to last around 40 minutes - plenty of time for excitement, cheering and enlightenment.

As curious as the event sounds, the background is serious: according to studies, the average sperm count worldwide has fallen by more than 50 percent in recent decades. The race is intended to playfully educate people about how strongly fertility is influenced by lifestyle, environmental factors and nutrition.

"Male fertility is declining very sharply. It's happening quietly and steadily, and nobody really talks about it," said Eric Zhu, the 17-year-old co-founder of Sperm Racing.
