Coenzyme Q10 and fertility: benefits and tips to optimise your chances

A key natural antioxidant at the cellular level

Coenzyme Q10 is present in every cell of the human body. It acts as a cofactor in the mitochondrial respiratory chain, enabling the production of ATP — the true fuel of our cells. This energy is indispensable for the optimal functioning of organs, particularly the ovaries and testes, whose cellular activity is intense [1]. It is the product to incorporate into your prenatal vitamins. 

Coenzyme Q10 and mitochondrial health

Mitochondria, often referred to as the "powerhouses" of cells, are essential to fertility. In women, they provide the energy needed for oocyte maturation and embryonic development [2]. In men, they support sperm motility [3]. With age, CoQ10 levels naturally decline, which may affect gamete development [4]. Targeted CoQ10 supplementation for fertility can help compensate for this decline and support mitochondrial function [5].

Impact on egg quality and ovarian reserve

One of the main challenges during the conception period is the gradual decline in ovarian reserve. Eggs age and become more susceptible to oxidative damage. Studies show that coenzyme Q10 supplements may help when wondering how to improve egg quality, by increasing their energy potential and reducing damage caused by free radicals [6]. It is a particularly beneficial product, especially for those with egg quality issues, to be used as part of a PCOS supplement or in cases of endometriosis, etc.

Support during ART or IVF

In the context of assisted reproduction, and particularly during in vitro fertilisation (IVF), egg quality is crucial. Several studies have shown that women taking CoQ10 before and during an ovarian stimulation protocol had better oocyte maturation rates and higher-quality embryos [7][8][9]. Coenzyme Q10 for fertility could therefore increase the chances of success with assisted reproduction treatments. It is generally compatible with products prescribed during ART journey. 

Testimonials and clinical study results

Many testimonials report an improvement in hormonal imbalance and therefore of the menstrual cycle, as well as a better ovarian response thanks to CoQ10. Clinical trials have also confirmed that supplemented patients had a higher pregnancy rate compared to control groups. These findings reinforce the idea that coenzyme Q10 for fertility represents a promising natural avenue for improving conception and helping to increase the chances of achieving a positive pregnancy test.

Effects on sperm motility and quality

In men, sperm concentration, morphology, and motility largely determine the ability to fertilise an egg. CoQ10 acts on fertility by improving sperm quality, particularly motility [10]. Several studies have demonstrated a significant improvement in sperm parameters, such as motility, after a few months of supplementation [11][12].

Influence on sperm DNA fragmentation rate

Another factor in male infertility is sperm DNA fragmentation, often linked to oxidative stress [13]. A male fertility test helps assess this point. 

This alteration reduces the chances of fertilisation and increases the risk of miscarriage [14]. CoQ10, through its antioxidant action, may help reduce this damage and support better genetic integrity, thereby improving male fertility [15].

Recommended coenzyme Q10 dose for each

CoQ10 exists in two forms: ubiquinone and ubiquinol. Ubiquinol is the reduced form, found as an oil or microencapsulated. Ubiquinone comes in powder form and is more commonly found in food supplements. The recommended dose is: 

• 200 mg for one male fertility food supplement. Our Cocooning+ Men product contains 200 mg of CoQ10, NAC (N-acetyl-cysteine), selenium and carnitine for optimal effectiveness. Selenium contributes to normal spermatogenesis. 
• 300 to 600 mg for one fertility food supplement woman. Our Ovo+ capsules provide 300 mg, with the addition of NAC (N-acetyl-cysteine), tryptophan and zinc. 

Combination with other supplements (NAC, vitamin E, zinc, folic acid)

To maximise its effectiveness, CoQ10 can be combined with other products. N-acetyl-cysteine (NAC) enhances the antioxidant action [16] and is also beneficial for both male and female fertility. 

Vitamin E protects cell membranes and zinc supports spermatogenesis and conception. Folic acid (vitamin B9) is an women's food supplement essential, particularly for cell division and the prevention of chromosomal abnormalities. Together, these nutrients create a beneficial synergy in cases of infertility.

That is why it is generally recommended to take a pregnancy food supplement when trying to conceive. These products help support your body during the conception journey and then throughout pregnancy. A multivitamin is an ideal choice to avoid accumulating multiple capsules and ensure all nutritional needs are met. 

Antioxidant-rich foods

Diet plays a key role in conception. Foods rich in antioxidants, such as berries, green vegetables, nuts and olive oil, support the protection of reproductive cells [17].

Mediterranean diet and conception

The Mediterranean diet is particularly recommended for optimising conception. It favours vegetables, fruits, wholegrains, oily fish rich in omega-3 and olive oil. Several studies have shown that this diet improves egg quality [18] and sperm quality [19], and increases the chances of success in assisted reproduction (ART).

Lifestyle habits to favour and to avoid

Beyond diet, certain lifestyle choices directly influence the risk of infertility. Smoking, alcohol and excess weight are risk factors, whilst good sleep, moderate physical activity and trying to manage stress better support conception. Combined with a coenzyme Q10 fertility supplement, these lifestyle choices significantly increase the chances of success.

Coenzyme Q10 for fertility is a valuable ally for couples experiencing difficulties conceiving. Its key role in cellular energy production and protection against oxidative stress makes it an essential product, both for women and for men. Whether as part of a natural approach or assisted reproduction (ART), coq10 for fertility offers natural, safe and effective support to help improve gamete quality and increase the chances of success. Combined with a balanced diet and a healthy lifestyle, it represents a comprehensive and promising approach to supporting conception.
