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 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.
In the study, scientists found that by injecting old mice with the antioxidant CoQ10, they were able to stimulate more eggs to develop, and the genetic quality of these eggs, their youthfulness, resembled those of mice in their reproductive prime. The offspring of these older mice, who were the equivalent of a 50-year human, were as healthy as those from younger mothers. It appeared that the CoQ10 was actually able to rejuvenate the mitochondria (the cell’s power source) and improve energy status of the eggs.
Another interesting study realated to rejuvenating women’s eggs was published by Dr. Jon Tilley in Nature Medicine. It shows that stem cells found in human ovaries may be capable of generating new eggs – suggesting, that under the right conditions, women could possibly keep producing new eggs much longer then previously thought.
Thus, it appears that the state of women’s eggs may be less predetermined than previously thought. And this gives women hope that there are things they can do to preserve and improve their fertility.
