Coenzyme Q10Coenzyme Q10 molecules are fat-soluble molecules that are both synthesized in the body and ingested in the diet and in supplements. Coenzyme Q10 is synthesized in the body in the same biological pathway as cholesterol. Bio-synthesis of Coenzyme Q10 begins to decline once humans reach their adult years. The reduced production of Coenzyme Q10 cannot be compensated in any practical... More pre-treatment of young low-prognosis patients with diminished ovarian reserve or poor ovarian response increased the patients’ ovarian response to stimulation and improved oocyte and embryo quality.
The CoQ10 pre-treatment was associated with improved pregnancy and live birth rates.

The women in the control group had a pregnancy rate of 17% and a 16% live birth rate.
The miscarriage rate was 9% in women from the CoQ10 group and 13% in women in the control group.
CoQ10 Supplementation and Women Needing Assisted Reproductive Technology
In the study, women under the age of 35 diagnosed with poor ovarian response were randomly assigned to take 200 milligrams of Coenzyme Q10Coenzyme Q10 molecules are fat-soluble molecules that are both synthesized in the body and ingested in the diet and in supplements. Coenzyme Q10 is synthesized in the body in the same biological pathway as cholesterol. Bio-synthesis of Coenzyme Q10 begins to decline once humans reach their adult years. The reduced production of Coenzyme Q10 cannot be compensated in any practical... More three times a day for 60 days (n=76) or to take a placebo (n=91).
The baseline characteristics of the women in the two study groups were comparable with respect to the following characteristics:
- age
- BMI
- duration of infertility
- ovarian reserve tests
- causes of infertility
Most of the women were diagnosed with primary infertility and had not tried assisted reproductive technology before.
CoQ10 Supplementation Safe and Well-Tolerated
No local or systemic side effects related to the use of oral CoQ10 supplements were reported in the study. The CoQ10 supplementation was safe and well-tolerated.
Outcomes of CoQ10 Pre-treatment of Women with Poor Ovarian Response
The study results demonstrated that pre-treatment with CoQ10 supplements had the following outcomes compared to the placebo treatment:
- Significantly lower amounts of gonadotrophin needed for stimulation
- Borderline shorter duration of gonadotrophin therapy
- Significantly higher median number of retrieved oocytes
- Significantly higher serum estradiol levels
- Significantly increased fertilization rate
- Significantly increased number of high-quality embryos
- Significantly lower rate of cancelled cycles
- Fewer cancelled embryo transfers
- Higher pregnancy and live birth rates

- The researchers attributed the beneficial effects of the CoQ10 pre-treatment on reproductive function to CoQ10’s effect on the antioxidative capacity and energy production in the oocytes.
CoQ10 Supplementation for Women Undergoing IVF-ET
In a smaller study of women undergoing in-vitro fertilization, researchers compared 15 women supplemented with Coenzyme Q10Coenzyme Q10 molecules are fat-soluble molecules that are both synthesized in the body and ingested in the diet and in supplements.

Outcomes of the CoQ10 Supplementation of Women undergoing IVF
- Significantly increased follicular fluid CoQ10 content
- Borderline significantly higher CoQ10 content in follicles containing oocytes
- Greater protection against free radical damage
- Significantly more scavenging of harmful free radicalsFree radicals are unstable and highly reactive molecules that are produced in the body during normal oxygen metabolism. Free radicals derived from oxygen are known as reactive oxygen species. Free radicals play both helpful and harmful roles in the body. Free radicals steal electrons from other substances in order to become stable. In so doing, the free radicals oxidize those...

They are substances that prevent the oxidation of other molecules and compounds. There are two broad categories of antioxidants: enzymatic and non-enzymatic. Non-enzymatic antioxidants are substances like Coenzyme Q10, vitamin C, vitamin E, glutathione, and various carotenoids. Prominent enzymatic antioxidants include catalase, glutathione peroxidase,...
