Coenzyme Q10 may boost sperm quality

Supplements of coenzyme Q10 (CoQ10) may improve the motility and density of sperm in infertile men.

Statistically significant but modest randomized controlled trial results suggest that CoQ10 may have potential clinical applications in infertile men (1). Coenzyme Q1010 supplementation of 300 mg for 26 weeks in infertile men resulted in an improvement in certain semen parameters such as sperm density and motility.

The researcher called for further prospective studies to evaluate if CoQ10 supplementation may play a role in achieving pregnancy in infertile couples.

CoQ10 has properties similar to vitamins, but since it is naturally synthesized in the body it is not classed as such. The coenzyme plays an important role in preserving levels of vitamin E and vitamin C. Sperm quality has been linked to the level of oxidative stress.

There is an ever-growing body of scientific data that shows substantial health benefits of CoQ10 supplementation for people suffering from angina, heart attack and hypertension. Clinical trials have also reported benefits for congestive heart failure.
