A new sport has emerged that takes sperm competition to an athletic level: sperm racing. Men will pit their sperm against others in a science-based competitive sport, culminating in the first-ever Sperm Racing World Cup.
How It Works
The event features 128 men, each representing a different country, whose semen samples race on a microscopic track. The mission is simple: the fastest sperm wins. Organizers aim to find the healthiest man alive and immortalize a nation.
According to the Sperm Racing World Cup recruitment video, the race will determine the champion with the swiftest swimmers.
Eligibility and Application
Competitors must be at least 18 years old, free of sexually transmitted diseases, and able to provide biological samples according to regulations. Applicants send a home kit with their semen sample to California, where it undergoes advanced lab techniques including incubation, sperm washing, pipetting, and centrifugation to isolate the most viable cells.
The selected athletes then race along a custom microfluidic track, covering a straight distance of 400 microns (about 0.02 inches), roughly the size of a salt granule. Every movement is magnified and broadcast live, with giant screens showing play-by-play progress, stats, and leaderboards. Fans can view competitors' health data, including body composition and biomarkers.
Prize and Participation
The tournament offers a $100,000 grand prize and has attracted over 10,000 applicants from more than 100 countries, including the United States, Iran, Israel, and North Korea. The event is set to take place in San Francisco next month at a location yet to be disclosed.
Origins and Purpose
Sperm racing was developed by tech entrepreneurs Eric Zhu, Garret Niconienko, Nick Small, and Shane Fan. Initially conceived to spotlight declining male fertility rates worldwide, the competition aims to make male fertility a topic people want to discuss and improve.
Fan told the Daily Mail that they are searching for the healthiest person possible for each country to compete, emphasizing the work involved in maintaining a healthy body. Zhu explained that the process prepares the most viable cells for racing.
Not the First Race
While organizers claim this is the first event of its kind, the inaugural sperm race took place in April 2025 in Los Angeles. Two college students competed live for a $10,000 prize before a crowd of hundreds. The winner, USC's Tristan Mykel, had a sperm finish time of one minute and three seconds.
Zhu insists the contest is about raising awareness, stating on the official site: "It's about making male fertility something people actually want to talk about, track and improve. We're taking a topic no one wants to touch and making it interesting, measurable, and weirdly changing this paradigm."
