He's not all that (BIGGEST myths about male fertility)
π¨ Men can have kids forever, right? π¨ Wrong!
While men do produce sperm for life, their fertility isn’t immune to time. Research shows:
β By 40, sperm motility and morphology decline significantly (Johnson et al., 2015)
β Sperm DNA fragmentation more than doubles after age 40 (Wyrobek et al., 2006)
β Risk of miscarriage increases when the father is over 40 (Sharma et al., 2015)
β Higher risk of autism & schizophrenia in children born to older dads (Kidd et al., 2001)
π¬ Why? Unlike eggs, sperm are constantly regenerating—but over time, mutations and chromosomal abnormalities increase. Even by just 40, sperm DNA fragmentation is significantly higher, impacting fertility and embryo development!
Remember, biological age is more important than chronological age.
If you’re doing average things, you’re more likely to fall within average sperm health statistics.
π‘ The takeaway? And don’t just assume his fertility is fine—test it!"
