How to Improve Egg Quality for IVF

By Dr (TCM) Attilio D'Alberto | Traditional Chinese Medicine Practitioner, Wokingham

Egg quality is the single most important determinant of IVF success — more than the number of eggs collected, more than the protocol, more than the embryologist's skill. A single chromosomally normal high-quality egg has a higher chance of producing a baby than ten poor-quality ones. The challenge is that egg quality is largely determined in the 90 days before ovulation (or egg collection) by what's happening to the developing follicles during their final maturation. The encouraging news is that this 90-day window is exactly where you have the most leverage. Through targeted supplements, acupuncture, Chinese herbal medicine, dietary changes and lifestyle modifications, egg quality can be measurably improved — particularly in women over 35, those with low AMH, those who have failed previous IVF cycles, and those preparing for their first IVF. This page is a comprehensive evidence-based guide.

What egg quality actually means

"Egg quality" includes several distinct biological factors:

• Chromosomal integrity — accuracy of meiosis (the division process that halves chromosome number); errors produce aneuploid eggs that fail to fertilise, fail to develop, or miscarry.
• Mitochondrial function — the energy supply for meiosis and early embryo development.
• Cytoplasmic quality — the egg's interior environment that supports the developing embryo.
• Spindle apparatus — the structure that physically separates chromosomes; sensitive to oxidative stress.
• Zona pellucida — the outer shell; needs to be the right thickness for fertilisation and implantation.
• Follicular fluid composition — antioxidants, hormones, growth factors that surround the developing egg.

Why egg quality matters more than quantity

In IVF, what determines success is not the number of eggs collected but the number of chromosomally normal embryos available for transfer. By age 35, around 50% of eggs are aneuploid; by 40, 70%; by 43, 80%+. So a 35-year-old who collects 10 eggs may have 5 chromosomally normal embryos available. A 43-year-old who collects 10 eggs may have only 2. This is why "low ovarian reserve" women in their twenties and early thirties often have surprisingly good IVF outcomes despite few eggs — those eggs are mostly chromosomally normal.

The 90-day window

Egg maturation is a 3-4 month process. The follicles that ovulate (or are collected) in any given cycle started their final maturation about 90 days earlier. This means:

• Whatever you do today influences the eggs ovulating in 3 months.
• Lifestyle changes need at least 90 days to show effect.
• Supplements are most useful when started 3 months before stimulation.
• Acupuncture and herbal preparation should run for 12 weeks minimum before any IVF cycle.
• Crash preparation in the few weeks before stimulation has limited benefit.
• Spermatogenesis is similar — sperm produced today started developing 74 days ago.

What causes egg quality decline

• Age — the dominant factor; mitochondrial decline accelerates after 35.
• Oxidative stress — damages mitochondria, DNA and the meiotic spindle.
• Smoking — significantly accelerates ovarian ageing.
• Alcohol — meaningful effect even at moderate intake.
• Chronic stress — cortisol affects HPO axis and ovarian function.
• Poor sleep — disrupts melatonin (a key follicular antioxidant) and HPO rhythm.
• Endometriosis — increased oxidative stress in pelvic environment.
• PCOS — high insulin and androgens disrupt follicle development.
• Obesity — increased systemic inflammation; insulin resistance.
• Underweight or restrictive eating — depletes resources for egg development.
• Endocrine disruptors — BPA, phthalates, parabens, pesticides.
• Heat exposure — for ovaries, less critical than for testes.
• Vitamin D and B12 deficiency.
• Chronic illness or autoimmune disease.
• Recent illness or significant stress — affects the cohort developing at that time.

The TCM understanding

In Chinese medicine, egg quality is an expression of Kidney jing — the inherited reproductive essence — alongside Kidney yin (cooling, nourishing fluid), blood (which forms the substrate for follicular development), and adequate uterine and ovarian circulation. Treatment focuses on:

• Nourishing Kidney jing — herbs and lifestyle that support the deepest reproductive reserves.
• Tonifying Kidney yin — particularly important from 35 onwards.
• Building blood — supports endometrium and follicular fluid.
• Moving blood when stasis is present — endometriosis, fibroids.
• Smoothing Liver qi — addressing stress that affects HPO axis.
• Warming Kidney yang — when cold-deficient picture present.

Diet for egg quality

• Mediterranean-style diet — best evidence base for fertility outcomes.
• Adequate protein — 1.2-1.5 g/kg/day; building blocks for follicles.
• Healthy fats — oily fish 2-3 times weekly, olive oil, avocado, nuts; building blocks for hormones and follicular fluid.
• Plenty of antioxidant-rich vegetables and berries — protect eggs from oxidative damage.
• Yin-nourishing foods (TCM) — eggs, slow-cooked meats, bone broth, black sesame, walnuts, goji berries.
• Iron-rich foods — particularly important for menstruating women.
• Reduce ultra-processed food, refined sugar, trans fats.
• Reduce alcohol significantly — 0-2 units per week when actively preparing.
• Limit caffeine to 1-2 cups daily.
• Stable blood sugar — protein at every meal.
• Adequate calories — undereating impairs follicular development.
• Reduce dairy in some women — particularly with phlegm-damp signs.
• Eat enough fish — DHA is structural to egg membranes.

CoQ10 — the most important supplement

Coenzyme Q10 (in the active form, ubiquinol) is the single most important supplement for egg quality. Mechanism:

• Critical component of the mitochondrial electron transport chain.
• Powerful antioxidant in the follicular fluid.
• Supports ATP (energy) production needed for meiosis.
• Levels decline with age; supplementation restores them.

Evidence:

• Multiple animal studies and several human RCTs support CoQ10 for egg quality, particularly in older women and poor responders.
• 2014 Bentov study: improved oocyte quality and fertilisation in women over 38.
• 2018 Xu et al meta-analysis: improved IVF outcomes in poor responders.

Dose: 200-600 mg daily of ubiquinol (the active reduced form is better absorbed than ubiquinone). Higher doses (400-600 mg) for women over 40 or with low AMH. Start at least 90 days before stimulation. Take with food (fat-soluble). Cautions: mild GI upset in some; avoid large doses with warfarin (mild interaction).

DHEA

Dehydroepiandrosterone (DHEA) is a precursor adrenal androgen that supports ovarian follicular development:

• Used widely in fertility clinics for women over 40 with low AMH or poor previous response.
• Increases follicle recruitment and IVF response in selected patients.
• Multiple RCTs and meta-analyses show benefit in poor responders; less clear in normal responders.
• Check baseline DHEA-S before starting; continue 12-16 weeks before IVF cycle.

Dose: 25-75 mg daily (typically 25 mg three times daily); discuss with your fertility clinic. Cautions: not in PCOS or hormone-sensitive conditions without specialist input; can cause acne, oily skin, mild mood effects; not appropriate for everyone.

Melatonin

Melatonin is best known as the sleep hormone but is also a potent antioxidant in the follicular fluid:

• One of the highest concentrations of any antioxidant in follicular fluid.
• Protects the developing egg from oxidative damage during meiosis.
• Levels in follicular fluid correlate with oocyte quality.
• Trials show improved fertilisation and embryo quality, particularly in poor responders.

Dose: 3 mg at bedtime, 90 days before stimulation. UK requires private prescription. Cautions: generally well tolerated; can cause vivid dreams; reduce dose if morning grogginess; check interactions with antidepressants.

Other key supplements

• Vitamin D3 1,000-4,000 IU — to blood level >75 nmol/L; deficiency impairs follicle development and implantation.
• Methylfolate 800 mcg + methylcobalamin (B12) 500 mcg + B6 (P5P) 25 mg — methylation cycle; lower homocysteine; particularly important in MTHFR variants.
• Omega-3 (DHA-rich, 1-2 g) — improves oocyte membrane fluidity; reduces inflammation in follicular environment.
• NAC 600-1,200 mg — antioxidant; particularly useful in PCOS and endometriosis.
• L-arginine 3-6 g — improves ovarian and uterine artery flow.
• Inositol 4 g + 100 mg d-chiro — egg quality in PCOS.
• Vitamin E 200-400 IU — antioxidant; supports follicle development.
• Zinc 15 mg, selenium 100-200 mcg — enzyme cofactors.
• Iron only with confirmed low ferritin.
• Pycnogenol or grape seed extract — vascular support.
• Resveratrol or astaxanthin — additional antioxidant support.
• L-arginine — supports ovarian blood flow.

Acupuncture

Acupuncture is one of the best-evidenced complementary interventions for IVF. Mechanisms relevant to egg quality:

• Improved ovarian and perifollicular blood flow on Doppler — directly relevant to follicular nutrition and oxygen supply.
• Reduced oxidative stress in follicular fluid.
• HPO-axis modulation — improved FSH/LH balance.
• Reduced sympathetic tone and cortisol.
• Improved endometrial receptivity.

Treatment weekly for 12 weeks before stimulation. Twice weekly during stimulation. Pre-and-post transfer protocol on transfer day. Typical points: SP 6, SP 8, KI 3, KI 7, BL 23, CV 4, CV 6, ST 29, LR 3 with electroacupuncture across abdominal points.

• Modified Si Wu Tang or Ba Zhen Tang — when blood deficiency dominates.
• Modified Gui Zhi Fu Ling Wan — when blood stasis (endometriosis, fibroids) coexists.
• Modified Xiao Yao San — Liver qi stagnation overlay.
• Cycle-phase prescribing — yin tonics in follicular phase, yang tonics in luteal phase.

Pharmaceutical-grade granules from Sun Ten Taiwan; prescription review each cycle.

Note: most fertility clinics ask patients to pause oral herbs during the active stimulation phase of IVF; herbal preparation in the months before, and acupuncture continuing throughout, is the standard combined approach.

Lifestyle

• Sleep 7-9 hours — supports melatonin (a key follicular antioxidant) and HPO axis.
• Stop smoking — significantly accelerates ovarian ageing.
• Reduce alcohol to 0-2 units per week — meaningful effect on egg quality.
• Strength training 2-3x per week — supports lean mass and metabolic health.
• Avoid extreme endurance training — depletes ovarian function in some women.
• Daily walking — improves pelvic circulation.
• Stress reduction — meditation, breathwork, yoga; cortisol matters.
• Healthy weight — both very low and very high BMI worsen egg quality.
• Reduce endocrine disruptors — BPA, phthalates, parabens, pesticides.
• Address thyroid and diabetes if present.
• Address sleep apnoea if present.

What to avoid

• Smoking — completely.
• Alcohol above 2 units/week during preparation.
• High-dose caffeine.
• Ultra-processed food and refined sugar.
• Trans fats.
• Aggressive intermittent fasting or restrictive dieting during the preparation window.
• Excessive endurance training.
• Excessive heat (sauna, hot tubs) — less critical for ovaries than testes but limit during stimulation.
• Endocrine disruptors where avoidable.
• Recreational drugs.
• Stopping medications without medical advice (if you're on them for other conditions).

Sperm quality matters too

Half of every embryo's chromosomes come from sperm, and sperm DNA fragmentation affects embryo development just as much as egg quality does. Male partner should:

• Take antioxidant supplements (CoQ10 200 mg, vitamin C 1 g, vitamin E 400 IU, zinc, selenium, L-carnitine 1-2 g, omega-3) for 90 days minimum.
• Methylfolate + methylcobalamin (B12).
• Reduce alcohol significantly.
• Stop smoking.
• Avoid heat (hot baths, saunas, laptop on lap).
• Wear loose underwear.
• Maintain healthy weight.
• Sleep 7-9 hours.
• Manage stress.
• Get a semen analysis with DNA fragmentation test before any IVF cycle.
• Acupuncture and Chinese herbs for male fertility — particularly with abnormal semen analysis.

Realistic timeline

• Days 1-30: dietary and lifestyle changes embedded; supplements started; baseline tests done.
• Days 30-60: early benefits — better sleep, energy, mood; cycle changes start.
• Days 60-90: peak preparation; the cohort of follicles destined for stimulation in 3 months are now in early development.
• Day 90+: ready for stimulation; the eggs collected reflect the past 3 months of preparation.
• For poor responders: 6 months of preparation may be needed before the first cycle.
• Between cycles: continue preparation; second and third cycles often produce better results than the first if preparation continues.

Frequently asked questions

What's the most important supplement for egg quality?

CoQ10 (ubiquinol) 200-600 mg daily, started 90 days before stimulation. Strongest evidence base of any single supplement.

How long do I need to prepare?

90 days minimum because the cohort of follicles for that cycle started maturing 90 days earlier. 6 months ideal for poor responders or women over 40.

Should I take DHEA?

Useful for women over 40 with low AMH or previous poor response. Discuss with your fertility clinic; check baseline DHEA-S; not appropriate in PCOS without specialist input.

Will Chinese medicine improve my egg quality?

Yes — the combination of cycle-phase acupuncture and Kidney yin/jing tonifying herbs improves ovarian blood flow, reduces oxidative stress, and supports follicle development. Effects build over 3 months.

What about melatonin?

3 mg at bedtime for 90 days before stimulation. Strong antioxidant in follicular fluid; particularly useful for poor responders. UK private prescription.

Can I take all these supplements at once?

Most combine safely. CoQ10 + methylfolate + B12 + D3 + omega-3 + NAC is a sensible base. Add DHEA and melatonin under specialist guidance. Always tell your IVF clinic what you're taking.

Will egg quality improve if I'm older?

Yes, modestly. You can't reverse ovarian ageing but you can optimise the eggs you have. Many women over 40 see meaningfully improved IVF outcomes after 3 months of structured preparation compared with cycles done without.
