Fertility is influenced by more than timing. Age, ovulation, the fallopian tubes, sperm health and other medical factors can all matter. Egg and sperm health are part of that picture, but it is important not to overpromise what food, lifestyle changes or supplements can change.
Why Egg Quality Matters
A woman is born with all the eggs she will ever have around one to two million. Over time, that number and quality naturally decline. By the mid-30s, fewer eggs are released, and the likelihood of chromosomal abnormalities increases, which can affect conception and pregnancy outcomes.
Age is the strongest established factor affecting egg number and the likelihood of chromosomal abnormalities. Healthy habits support general preconception health, but there is no supplement or lifestyle programme proven to reverse age-related egg-quality changes or restore ovarian reserve.
Ways to support preconception health
- Eat a balanced diet: Aim for a varied pattern that covers essential nutrients rather than treating individual antioxidants as egg-quality treatments.
- Support overall health: Regular meals, movement and appropriate care for conditions such as diabetes or PCOS can be useful parts of preconception health.
- Avoid smoking and recreational drugs: These can affect reproductive and general health. Keep alcohol within current health guidance and avoid it in pregnancy.
- Protect sleep and mental wellbeing: These support health during trying to conceive, but stress should not be blamed for infertility.
Preconception supplements can provide nutrients, but they should not be described as proven ways to improve egg quality. NHS preconception guidance prioritises essentials such as folic acid and vitamin D, with other supplements considered in the context of diet, medicines and individual needs.
Sperm Health: More Than Just Count
Sperm quality isn’t only about quantity it’s about motility (movement), morphology (shape), and DNA integrity. Research shows that sperm health can change within about three months, as that’s how long new sperm take to develop.
Factors that can support sperm health
- Maintain a healthy weight: Excess body fat can affect testosterone and sperm production.
- Eat a balanced diet: Nutrient adequacy matters, but individual vitamins or supplements should not be presented as guaranteed ways to improve fertility.
- Stay cool: Avoid excessive heat from laptops or saunas on the lap area.
- Cut back on toxins: Smoking, heavy alcohol use, and recreational drugs can harm sperm DNA.
If you are comparing male fertility supplements, use them as nutritional support rather than as a substitute for semen analysis, medical assessment or treatment where those are needed.
The Power of Preconception Care
Preconception health isn’t just for those ready to conceive today it’s a form of body literacy. Understanding your fertility empowers you to make informed choices about your health, family planning, and overall wellbeing.
Consider fertility testing or consultations to learn more about:
- Ovarian reserve testing (AMH, FSH, AFC)
- Semen analysis
- Hormone balance panels
- Nutritional and lifestyle assessments
If you use a preconception supplement, treat it as nutritional support rather than a fertility treatment. Our preconception health guide covers the wider evidence-based basics.

Key Takeaway
Egg and sperm factors both contribute to fertility, but they are not equally modifiable. Age-related changes in egg quality cannot be reversed by supplements, while some aspects of sperm health can be influenced by medical conditions and lifestyle. The useful goal is informed preconception care, not chasing a product that promises to “optimise” reproductive cells.
This National Fertility Awareness Week, let’s normalise conversations around fertility because awareness is the first step to empowerment.
Because fertility health is whole-body health.
