Diet during pregnancy doesn't just build a baby; it actively programs their DNA by placing epigenetic "switches" on genes. These switches influence the baby's future risk for diseases like diabetes, obesity, and even psychiatric disorders, shaping their health for life.
By framing sperm health as an entertaining sport, Eric Zhu's venture makes a taboo topic mainstream. This encourages men to monitor their fertility and overall health, which they might otherwise ignore due to social stigma, potentially helping to solve the male infertility crisis.
