Coenzyme Q10 in Male and Female Infertility

ABSTRACT

Infertility is a medical condition that can cause psychological, physical, mental, spiritual, and medical detriments to the patient. Infertility can also be a marker of an underlying chronic disease associated with infertility. It is currently affecting one out of six couples worldwide. The pathophysiology of male and female infertility is multifactorial and still not fully elucidated. Both are related to an imbalance between the production of Reactive Oxygen Species (ROS) and antioxidant defences. Antioxidants are biological and chemical compounds that are synthesized endogenously or exogenously, counteract oxidative stress and act as free radical scavengers. Coenzyme Q10 (CoQ10) is a lipidsoluble quinone acting as an effective antioxidant, which prevents lipid peroxidation and DNA oxidation. It empowers the body’s energy production cycle through Adenosine Triphosphate (ATP) synthesis and has long been used to ameliorate infertility outcomes. Evidence suggests that CoQ10 shows beneficial effects on semen quality, quantity, and mobility in male infertility. Moreover, the potential benefits of oral antioxidants on female infertility treatment are being increasingly investigated, including CoQ10. CoQ10 treatment significantly increases fertilization rate, the number of high-quality embryos, and higher clinical pregnancy and live birth rates. Furthermore, CoQ10 administration enhances ovarian response to stimulation and improves oocyte and embryo quality. Hence, available evidence and clinical studies suggest that CoQ10 supplementation could be considered an inexpensive, safe therapy to enhance infertility treatment in men and women of reproductive age
