Coq10 increases fertility egg quality

CoQ10 is a naturally occurring nutrient that is needed for energy production. CoQ10 has potent antioxidant properties and cell membrane stabilizing properties, which make it beneficial for fertility and egg quality. CoQ10 works within the mitochondria (the cellular power stations) in the cells and is essential for energy production. 

Until recently, CoQ10 was not thought to be a needed supplement, as all normal tissue produces its own CoQ10. However, this production decreases naturally with age and is also lowered by certain drugs, including statins.  It is also known that the human egg has the greatest energy demand of any cell in the body. Energy demand goes up considerably during the process of follicle growth. It was therefore theorized that supplementing with CoQ10 could improve egg quality.

A recent study from Mount Sinai Hospital in Toronto on Coenzyme Q10 and egg quality suggests that, in fact, it may possibly improve egg quality and slow down or even reverse the aging process.
