Does coenzyme Q10 supplementation improve fertility outcomes?
Increased oxidative stress has been identified as a pathogenetic mechanism in female infertility. However, the effect of specific antioxidants, such as coenzyme Q10 (CoQ10), on the outcomes after Assisted Reproductive Technologies (ART) has not been clarified.
The aim of this study was to systematically review and meta-analyze the best available evidence regarding the effect of CoQ10 supplementation on clinical pregnancy (CPR), live birth (LBR), and miscarriage rates (MR) compared with placebo or no-treatment in women with infertility undergoing ART.
Five randomized-controlled trials fulfilled eligibility criteria (449 infertile women; 215 in CoQ10 group and 234 in placebo/no treatment group). Oral supplementation of CoQ10 resulted in an increase of CPR when compared with placebo or no-treatment (28.8% vs. 14.1%, respectively).This effect remained significant when women with poor ovarian response and polycystic ovarian syndrome were analyzed separately. No difference between groups was observed regarding LBR and MR.
The conclusion of the study in the journal was that the oral supplementation of CoQ10 may increase CPR when compared with placebo or no-treatment, in women with infertility undergoing ART procedures, without an effect on LBR or MR.
These types of supplements should only be taken on the recommendation of your doctor.
