Key point: Egg quality is largely determined by age โ but it is not entirely beyond your influence. Several evidence-supported interventions, started 8โ12 weeks before IVF or conception attempts, can meaningfully support egg development and mitochondrial health.
Egg quality refers to the genetic integrity and energy capacity of an egg. A high-quality egg has the correct number of chromosomes (normal ploidy) and sufficient mitochondrial energy to complete fertilisation, early cell division, and implantation.
Poor egg quality โ often characterised by chromosomal abnormalities called aneuploidy โ is the leading cause of:
The main driver of poor egg quality is age โ after 35, the rate of chromosomal errors in eggs increases significantly. But beyond age, several modifiable factors affect how well eggs develop and function.
These are the supplements with published clinical evidence or strong biological rationale. Start them 8โ12 weeks before your IVF cycle or intended conception period for maximum effect โ this is the time frame over which follicles mature from primordial to preovulatory stage.
The most evidence-backed supplement for egg quality. CoQ10 supports mitochondrial function โ eggs are among the most energy-demanding cells in the body, requiring mitochondrial ATP for spindle formation and chromosome segregation. Low CoQ10 = increased chromosomal errors. Multiple RCTs show improvement in IVF outcomes. Ubiquinol form has better absorption in older patients.
Increases intra-follicular androgen levels, supporting granulosa cell function and follicle development in women with poor ovarian reserve. Multiple studies show improved AFC, fewer cancelled cycles, and better embryo quality in poor responders. Not suitable for all patients โ must be prescribed and monitored by a specialist.
Vitamin D receptors are present in ovarian tissue and play a role in follicle development. Vitamin D deficiency (very common in India) is associated with lower IVF success rates. Testing and correcting Vitamin D before IVF is inexpensive and well-evidenced. Dosing depends on your baseline level โ typically 2,000โ5,000 IU/day.
DHA (docosahexaenoic acid) is incorporated into egg cell membranes, improving membrane fluidity and receptor function. Associated with better embryo development and pregnancy rates in several studies. Also beneficial for endometrial receptivity and early fetal neurodevelopment.
Essential for DNA synthesis and repair in rapidly dividing cells โ critical during early embryo development. Women with MTHFR gene variants may benefit from methylfolate form. Start at least 3 months before attempting conception or IVF.
Melatonin is a potent antioxidant that concentrates in follicular fluid, protecting eggs from oxidative stress. Some IVF studies show improved fertilisation rates and embryo quality. More research needed but safe and inexpensive. Discuss with your doctor before adding.
Smoking significantly accelerates ovarian ageing โ women who smoke have AMH levels 20โ30% lower than non-smokers of the same age. Cigarette smoke contains chemicals that cause DNA damage in eggs and accelerate follicle death. If you smoke, stopping is more valuable than any supplement. Stop at least 3 months before IVF or conception attempts.
Both overweight and underweight affect egg quality. Excess fat tissue produces excess oestrogen, disrupting hormonal balance. Low body fat impairs ovulation. A BMI of 18.5โ24.9 is optimal for fertility. Even a 5โ10% weight change in the right direction can meaningfully improve egg quality and IVF response.
Oxidative stress damages DNA in eggs. Antioxidants neutralise free radicals. A Mediterranean-style diet โ high in fruits, vegetables, whole grains, olive oil, legumes, and oily fish โ has the strongest evidence for fertility and IVF outcomes of any dietary pattern.
Key foods: berries (blueberries, strawberries), leafy greens (spinach, kale), nuts (almonds, walnuts), olive oil, fatty fish (mackerel, sardines), eggs, lentils, colourful vegetables. Reduce processed food, refined sugar, and trans fats.
Chronic psychological stress elevates cortisol, which suppresses gonadotrophin signalling and may impair follicle development. Yoga, meditation, walking, and counselling are all evidence-backed strategies for reducing fertility-related stress. Our clinic provides access to fertility counselling support.
Even moderate alcohol consumption is associated with reduced IVF success rates. Alcohol increases oxidative stress and affects hormonal balance. Zero alcohol during your IVF preparation period is the safest approach.
Sleep is when cells repair and hormonal recovery occurs. Chronic sleep deprivation disrupts LH pulsatility (critical for ovulation), increases cortisol, and reduces melatonin โ the natural antioxidant protecting your eggs at night.
The internet is full of products claiming to "rejuvenate" or "boost" egg quality. Here's what lacks credible evidence:
Always discuss any supplement or protocol with your fertility specialist before starting โ some can interfere with IVF medications.
A follicle takes approximately 90 days (3 months) to mature from a primordial follicle to a preovulatory egg. This means interventions started 3 months (ideally) before IVF egg retrieval or conception attempt have the best chance of influencing the eggs that will actually be used.
Bottom line: Egg quality is not entirely within your control โ age is the biggest factor. But the 90-day preparation window before IVF is your best opportunity to give every egg its best possible start. CoQ10, Vitamin D correction, quitting smoking, and a Mediterranean diet are your most evidence-supported investments.
