Abstract

Objective

To evaluate the effect of coenzyme Q10 treatments in male infertility, specifically in these parameters: live birth and pregnancy rates, CoQ10 seminal concentration, sperm concentration, and sperm motility.

Materials and methods

Systematic review and meta-analysis in male infertility patients with CoQ10 oral treatments. Three trials were included: 149 males in CoQ10 group and 147 males in placebo group.

Results

None of the included trials provided any data regarding live births. The results of this meta-analysis show that supplementing infertile men with CoQ10 does not increase pregnancy rates. The analysis showed, among patients receiving CoQ10 treatment, a statistically significant increase in: CoQ10 seminal concentration (RR 49.55, 95 % CI 46.44 to 52.66, I2 = 17 %), sperm concentration (RR 5.33, 95 % CI 4.18 to 6.47, I2 = 58 %), and sperm motility (RR 4.50, 95 % CI 3.92 to 5.08, I2 = 0 %)

Conclusion

There is no evidence in the literature that CoQ10 increases either live birth or pregnancy rates, but there is a global improvement in sperm parameters. Adequately powered, robust trials of individual and combination antioxidant therapies are required to guide clinical practice.

Capsule Oral treatment with Coenzyme Q10 improves sperm concentration and sperm motility, but there is no evidence that increases either live birth or pregnancy rates.
