In what may become the most bizarre and innovative event in medical entertainment history, the world is about to witness its first-ever live sperm race—and yes, it’s exactly what it sounds like. On April 25, 2025, inside the Hollywood Palladium, thousands will gather to cheer on what might be the most microscopic competitors to ever grace a stadium. But this isn’t just spectacle for the sake of curiosity—this event could change how the public perceives male fertility forever.
The creators behind this unusual race are four teenage founders from the U.S., including 17-year-old Eric Zhu, whose mission is to make sperm health an entertaining, mainstream conversation. Zhu and his team, through their startup Sperm Racing, are aiming to flip the script on fertility discussions, particularly focused on the decline in male sperm quality over the past five decades. With studies reporting over a 50% drop in sperm counts since the 1970s, this event may be shocking—but it’s also timely.
Two college students—one from the University of Southern California and one from UCLA—have submitted sperm samples, which will compete through a specially engineered 20cm track mimicking the female reproductive system. These sperm will be filmed using 40x magnification and projected live on big screens. Spectators will be able to watch them swim at an average speed of 5mm per minute—yes, that slow—and the whole race is expected to last around 40 minutes, give or take a few dramatic photo finishes.
What makes this even more surreal is the addition of live commentary, instant replays, and leaderboard tracking. It’s a full-blown sporting event—just on a microscopic scale. The startup is even partnering with Nucleus Genomics and has secured $1.5 million in funding, backed in part by billionaire Joe Liemandt. They’re not stopping there—audiences will also be able to bet on the winner through the decentralized prediction market Polymarket, adding a whole new layer of chaos and excitement to this very unconventional race.
According to Zhu, the mission is dead serious, even if the method is unusual. “Most people don’t realize how important sperm motility is until they’re already facing fertility issues,” he told The Times. “We want people to have that awareness earlier—this is our way of starting that conversation.”
The race will be limited to samples from donors who’ve been screened for overall health and normal sperm parameters. The entire setup was vetted by reproductive specialists and is designed to be both medically accurate and highly viewable. Experts from NIH’s fertility division are even keeping a close eye on how the public responds. Early ticket demand suggests they’re onto something big—literally thousands of people have already RSVP’d, with Ticketmaster listings showing rapid sellouts.

On social media, the reactions have been wild. One viral tweet from @NickDrombosky joked, “This is the March Madness of my vas deferens.” Others, like @scienceisdope, praised the event for turning something awkward into educational gold. Even celebrities are catching on—Kylie Jenner reposted the teaser with the caption “I’m weirdly obsessed with this.”
The launch date for the official sperm racing event is the 25th of April so expect this to cook. Look for dips, NFA. https://twitter.com/iruneden/status/1909928347200610304— Adam (@iruneden) April 9, 2025
The production team is pulling out all the stops: holographic overlays, AI-powered tracking tech, and real-time medical commentary from fertility experts. Live-stream options will be available globally, and coverage has already been picked up by outlets like BBC, VICE, and Gizmodo. Meanwhile, discussions have exploded on forums like Reddit and MetaFilter.
Will this become a one-time gimmick or the beginning of a strange new sport? No one knows. But one thing is certain—by April 25, all eyes will be on what’s usually kept private, silent, and unspoken. The sperm race is real.
