Sperm racing, a concept that began as a joke, has become a trend among tech entrepreneurs. The idea was pioneered by teenage founder Eric Zhu, who went viral with his first sperm race in April. Initially, college students provided sperm samples that were analysed and turned into an animated race visualising the fastest offerings. The company has since developed a real-time race mechanism and secured $10 million in seed funding, with investors valuing it at $75 million.
The company now presents sperm racing as a health initiative, citing declining male fertility. Its manifesto states: 'Male fertility is declining. Like, a lot. Sperm racing isn’t just about racing sperm... It’s about turning health into a competition. It’s about making male fertility something people actually want to talk about, track and improve.' The company also sells a supplement called Sperm Worms.
Critics argue that framing health as a competition is problematic. The trend reflects Silicon Valley's fixation on traditional masculinity, body optimisation, and a growing interest in fertility that overlaps with eugenics. Tech figures like Mark Zuckerberg have lamented the lack of 'masculine energy' in corporate culture, while others host 'T Parties' to compare testosterone levels.
Zhu has reportedly partnered with Total Frat Move to run sperm races at colleges. While some see the initiative as a way to engage young men in reproductive health, others question the underlying message and the allocation of venture capital to such ventures.
