Coenzyme Q10 is a fat-soluble antioxidant that is found in high concentration in our cell’s energy-producing organelle, the mitochondria.
The energy the mitochondria produces is crucial for many of the cell functions such as cell division and cell death signaling. In the mitochondria, CoQ10 acts as a powerful antioxidant, inhibiting free radical generation and preventing cell damage which helps the mitochondria produce energy more efficiently.
CoQ10 is made by all of our cells as without it, cells cannot produce energy.
CoQ10 can also be obtained through our diet. Rich source of CoQ10 includes eggs, fatty fish, meats, peanuts, and poultry.
Initially, CoQ10 was discovered as a supplement that improves cardiovascular conditions. It has shown to reduce blood pressure and improves the symptoms of congestive heart failure. CoQ10 was also found to be beneficial in the treatment of neurological diseases, such as Parkinson’s.
CoQ10 is a potent antioxidant. It protects the cells from damage caused by free oxygen radicals, byproducts of energy production which can be beneficial in boosting physical performance.
Many studies published in recent years have demonstrated that CoQ10 also plays a beneficial role in reproduction health.
Numerous studies have shown a strong association between inadequate mitochondrial function and infertility. In light of the central role of CoQ10 in mitochondrial function, researchers hypothesized that CoQ10 is also involved in infertility.
Researchers found that CoQ10 levels decrease with age and more profoundly in women in their late 30s and after. This decline co-occurs with the age-related decline in fertility further emphasizing the potential role CoQ10 plays in ovarian aging .
In addition, researchers found that eggs of older women do not produce enough CoQ10 , which is associated with age-related decline in egg quality and quantity. This decline could be reversed by CoQ10 supplementation .
CoQ10 supplement can also impact IVF outcome . Researchers demonstrated that higher concentrations of CoQ10 were associated with better quality embryos and higher pregnancy rates.
Furthermore, pretreatment with coenzyme Q10 improves ovarian response and embryo quality 
Men can also benefit from CoQ10 supplementation. CoQ10 levels in the semen correlate with sperm counts and motility . Supplementation with Co10 may result in higher sperm counts and improved sperm motility. Further studies are needed to determine whether there is also an effect on fertility rate.
It is important to note that CoQ10 is classified as a natural health product (NHP) and marketed as a dietary supplement. It appears to be safe and to produce few side effects when taken as directed. However, the supplement industry is not regulated, and composition varies widely between manufacturers. Make sure you consult your fertility specialist before taking CoQ10.
