Tech entrepreneurs Eric Zhu, Garret Niconienko, Nick Small and Shane Fan have announced what they're claiming to be the world's first 'Sperm Racing World Cup', a science-based competitive sport. The race will see 128 semen samples, each from a different country, racing to win a $100,000 (₹95 lakh) cash prize in San Francisco. The competition already has 10,000 applications.
