US-HEALTH-FERTILITY-MEN

A microscope and visualization equipment is configured before a Sperm Racing competition in Los Angeles, California on April 25, 2025.Tristan Mykel of USC holds a golden sperm trophy after winning the Sperm Racing competition championship in Los Angeles, California on April 25, 2025. At the Los Angeles event on Friday night, a man in a lab coat used pipettes to place samples of semen -- collected from contestants ahead of time -- onto tiny two-millimeter-long "tracks." The race track is magnified 100 times by a microscope, then filmed by a camera that 17-year-old high schooler Eric Zhu says transfers the image to a 3D animation software before the final video is broadcast to the audience. The unusual sport was invented by Zhu, who raised over a million dollars to organize the event to raise awareness of male infertility. (Photo by Patrick T. Fallon / AFP) (Photo by PATRICK T.
