As fertility care evolves, more clinicians are recognising the role nutrition and supplements play in supporting reproductive health. One nutrient gaining attention is Coenzyme Q10 (CoQ10), a compound that helps cells produce energy and protects them from oxidative stress, both of which are essential for healthy eggs and sperm.
How CoQ10 Supports Fertility
A 2026 study by Derbyshire, Ostojic, and Alahmar highlights how CoQ10 enhances energy production and antioxidant defence in reproductive cells, noting that this process can support sperm function, egg quality, and early embryo development.
This an important insight when advising patients with age-related fertility concerns or oxidative stress risk factors.
Why Women Benefit from CoQ10
In women, CoQ10 helps maintain a healthy environment for developing eggs, protecting them from oxidative damage that can accumulate with age. Supplementation has been linked to better egg quality, improved embryo development, and stronger ovarian response, particularly for women over 35. It can also support patients with PCOS, helping them maintain hormonal and metabolic balance, a practical tool for improving overall fertility outcomes.
Why Men Benefit from CoQ10
Male reproductive cells are also highly energy-dependent and sensitive to oxidative stress. Evidence shows CoQ10 can improve sperm motility, concentration, and morphology, while strengthening antioxidant defences in seminal fluid. This makes CoQ10 a key consideration when managing male factor infertility.
Putting CoQ10 into Practice
CoQ10 can be part of a holistic fertility strategy, alongside diet, lifestyle, and other targeted supplements. While dosage and duration should be tailored to individual patients, the growing evidence supports its role in optimising both egg and sperm health, particularly in patients with age-related declines or oxidative stress concerns.
