Short answer: Q10 has been studied for assisted reproduction, with some positive results for pregnancy and laboratory measures. Its benefit for live birth is still uncertain. Ubiquinol is a form of Q10, but results for Q10 in general do not show that ubiquinol specifically provides better fertility outcomes. Discuss its use with your clinic based on your diagnosis and treatment.
Why is Q10 being studied in egg cells?
Q10 participates in the cells' energy production and acts as an antioxidant. This makes the substance interesting in research on egg cell maturation and oxidative stress. A biological explanation is, however, only a starting point: it needs to be followed by studies that show whether the treatment actually helps people.
Animal experiments can contribute knowledge about mechanisms, but cannot be used as a promise of rejuvenated eggs or restored fertility in a woman.
What results have the studies measured?
In Florou and colleagues' meta-analysis from 2020, five randomized studies with a total of 449 women were included. The group that received Q10 had a higher proportion of clinical pregnancies, but no statistically significant difference in live birth or miscarriage. The uncertainty in the latter results was large.
It is therefore important to ask whether a claim applies to the number of eggs, embryo assessment, pregnancy on ultrasound, or born children. These outcomes are not interchangeable. Studies on people with fertility problems do not automatically provide answers for those trying to get pregnant without treatment.
Ubiquinol and ubiquinone: what does the form mean?
Ubiquinol and ubiquinone are two forms of the same substance. The product's form, preparation, and dose need to be distinguished from its clinical effect. A claim about better absorption is not in itself evidence of more pregnancies or live born children. The sources used here do not justify designating ubiquinol as a general first choice for fertility problems.
Dosage and treatment need to be discussed together
The design of the studies varies, so there is no dose or treatment duration that can be recommended to everyone based on these results. Following a study dose on your own does not replace an assessment of benefit and risk.
NCCIH describes, among other things, gastrointestinal problems and possible interactions with warfarin and insulin. Tell the clinic which supplements you use and ask what applies during stimulation, after retrieval, and with a positive pregnancy test.
