Female fertility decreases with age due to a decline in the number and quality of available eggs.

CoQ10 is directly involved in this process. As you age, CoQ10 production slows, making the body
less effective at protecting the eggs from oxidative damage.

Supplementing with CoQ10 seems to help and may even reverse this age-related decline in egg
quality and quantity.

Male sperm is susceptible to the effects of oxidative damage, which may result in reduced sperm
count, poor sperm quality and infertility.
