When it comes to female and male fertility, the health and quality of egg and sperm cells play a crucial role. These cells require a significant amount of energy to develop and are susceptible to oxidative damage. One key nutrient that has gained attention in recent years for its potential benefits in supporting fertility is Coenzyme Q10 (CoQ10). CoQ10 is one of the main nutrients that I recommend in my naturopathic fertility practice. In this article, I will review what CoQ10 is, how it works, and the potential benefits it may offer for both male and female fertility. Let’s dive in shall we!

What is CoQ10?

CoQ10 is a naturally occurring biomolecule in the human body, and it is present in every cell. It exists in two common forms: ubiquinone and ubiquinol. CoQ10 acts as a potent antioxidant and plays a critical role in cellular energy generation through the electron transport chain.

CoQ10 and Female Fertility

CoQ10 has been studied for its potential benefits in enhancing egg quality and female fertility. As a powerful antioxidant, CoQ10 helps protect the eggs from oxidative damage, which can impact their quality. Several studies have shown that CoQ10 supplementation can improve the mitochondrial function within the eggs, leading to better cellular energy production and potentially improved fertility outcomes (1) (2) (3) (4).

Additionally, CoQ10 has been extensively studied in the assisted reproduction technology world, and has been shown to be beneficial in cases of PCOS (polycystic ovary syndrome) and poor ovarian reserve (5). For instance, co-administration of Coenzyme Q10 and Letrozole (which is an ovulation induction medication) versus Letrozole alone improves ovarian response, ovulation rates, endometrial thickness and pregnancy rates in PCOS patients in comparison to Letrozole alone (6). Furthermore, pretreatment with Coenzyme Q10 in women with low ovarian reserve undergoing IVF or ICSI has been shown to improve response to ovarian stimulation medications, increase the number of eggs retrieved, increase fertilization rates, and increase the number of high quality embryos (7).

CoQ10 and Male Fertility

CoQ10 is not only beneficial for female fertility but also for male fertility. Sperm cells also require a significant amount of energy to develop and are susceptible to oxidative damage. CoQ10's role as an antioxidant helps protect sperm cells from oxidative stress, which can negatively impact sperm health. Studies have shown that CoQ10 supplementation can improve sperm parameters, including sperm count, motility, and morphology.. These improvements may increase the chances of successful fertilization and pregnancy (8) (9) (10) (11).

Dosage and Considerations

When considering CoQ10 supplementation, it is important to consult with a healthcare provider, especially if you are currently taking any medications. The dosage of CoQ10 for fertility purposes may vary, but generally, a daily dosage of 200-600 mg is recommended depending on the underlying cause of your fertility challenges.

Conclusion

Coenzyme Q10 (CoQ10) has emerged as a promising nutrient for improving fertility outcomes. Its powerful antioxidant properties and role in cellular energy generation make it a valuable addition to the fertility journey for both men and women. CoQ10 supplementation may help support egg and sperm quality, and enhance the chances of a successful pregnancy.
