Fertility is Impacted by Optimal Ubiquinol Levels

With Australia’s fertility rate at a record low, Australasia’s leading fertility experts and healthcare practitioners are looking at the essential role of the mitochondria, and optimal ubiquinol levels, and links to fertility health. 

In Australia, one in six couples experience infertility[1], with 30% of cases attributed to males, 30% to females and the remaining 40% due to combined factors.[2] As such, 50% of infertility cases in Australia are linked to male fertility issues.[3] 

Oxidative stress and mitochondrial dysfunction are among the most investigated mechanisms for reduced fertility.[4,5] 

Mitochondria are organelles found in all body cells. They are the “powerhouses” of cells, generating energy (ATP) that is fuelled by the body’s production of ubiquinol. The highest number of mitochondria are found in females within oocytes (eggs) and in males within sperm. As a result, these two cells, responsible for creating life, contain the highest concentrations of ubiquinol. Ubiquinol ensures that each cell functions optimally and provides the energy required for their function. 

With this considered, scientists are focusing on the link between mitochondrial dysfunction, ubiquinol depletion and fertility health in an effort to ‘stop the clock’ on declining fertility rates. 

According to Australia’s leading fertility expert Dr Leah Hechtman, numerous clinical studies have shown that ubiquinol supports improved sperm morphology, motility and density, substantially changing the way we look at male fertility issues.[1,6,7] 

“Male sperm count has declined by more than 50% in the past 50 to 60 years,” explained Hechtman. “The process of spermatogenesis is highly influenced by exposure to variables such as oxidative stress. Lifestyle factors such as stress, a poor diet, smoking and ageing have a negative impact on male reproductive function,” she continued.  

“What we’ve seen through these factors and clinical studies is that ubiquinol can help to improve sperm count, motility and morphology, therefore positively influencing male fertility rates.” 

Several studies validate ubiquinol’s role in assisting female reproductive health. Thakur et al (2016) showed that, after taking a ubiquinol supplement for four months, 50 non-menstruating infertile women saw their FSH levels triple and LH levels double.[6] In women with amenorrhoea, stimulation of FSH and LH is essential for them to ovulate and will influence if they can conceive at all. 

“Regarding female fertility, the female egg contains the highest concentration of mitochondria,” added Hechtman. “Because ubiquinol optimises mitochondrial function, this can act as a support mechanism for female reproductive health.” 

Hechtman said that events like World Fertility Day are so important in strengthening the message regarding fertility on the global health agenda. She also urged Australians to have a closer look at lifestyle factors such as diet, exercise, sleep and stress levels, all which play a critical role in supporting fertility and reproductive health.
