Women apparently aren’t the only ones who hear that biological clock ticking.
A new study released Tuesday is the first to show that sperm quality declines when a man hits middle age.
Researchers at the Colorado Centre for Reproductive Medicine looked at the impact of age on male mice and found the rodents that had reached the middle of their lives experienced more fertility issues than the younger males.
The study’s lead author said some women are choosing to freeze their eggs in their early 30s and maybe men should check out their options too.
