Key Takeaways

  • Get a semen analysis if struggling with fertility – male factors contribute to 50% of infertility cases.
  • Request sperm DNA fragmentation testing if experiencing unexplained infertility or multiple IVF failures, despite current guidelines discouraging it.
  • Avoid heat exposure to testicles – high temperatures can wipe out sperm production for 3 months.
  • Report symptoms to your doctor – men often underreport health issues that may affect fertility.
  • Address metabolic health – conditions like prediabetes and kidney disease directly impact sperm quality.

Notable Quotes

“When you ignore a situation, it can only get worse.”

“Infertility is a disease and it is not managed in that way with a man.”

Bottom Line

Men must proactively test and optimize their fertility health – demand comprehensive testing, avoid heat exposure, and address underlying metabolic issues that impact sperm quality.
