Infertility Is On the Rise.
Here’s One Overlooked Cause:
Male fertility has dropped by over 50% in the last 50 years. Here's how underwear is part of the issue.
Conventional Underwear
Most guys still wear conventional underwear made from toxic synthetics like polyester.
Why it's Bad
These materials often contain chemicals linked to lower sperm count, decreased testosterone, and reproductive issues.
How it Affects Him
His skin absorbs traces of what it touches. Where do those chemicals sit all day? Right where it matters most for your future family.
Bottom Line
If you're trying to start a family—or just want to protect his ability to—toxic underwear shouldn't stand in the way.
