IVF Preparation: How to Optimise Your Body for IVF Success

Preparing for IVF is one of the most significant health journeys a couple can undertake. While your clinic handles the medical protocol — stimulation, egg retrieval, fertilisation, and transfer — there is a meaningful window before treatment begins where your own preparation can genuinely shift outcomes.

This guide covers evidence-based IVF preparation strategies for both partners: supplements, nutrition, lifestyle, and mindset. Whether your IVF cycle is weeks or months away, starting now gives you the best possible foundation. Conceive Plus supports couples through every stage of fertility treatment preparation.

Why IVF Preparation Matters: The 90-Day Window

The single most important concept in IVF preparation is the follicular development timeline. Eggs that will be retrieved in your stimulation cycle began their development approximately 90 days before retrieval. Similarly, sperm that will fertilise the eggs were produced about 70–74 days beforehand.

This means that what you eat, how you sleep, how much you exercise, and which supplements you take in the 3 months before your IVF cycle directly influences the quality of the eggs and sperm that will be used. Interventions made the week before egg retrieval have minimal impact on egg quality — the damage or benefit was set months earlier.

If your IVF cycle is scheduled for 3 months from now, your preparation window is open right now. If it's scheduled sooner, start immediately with what you can.

IVF Preparation for Women: Optimising Egg Quality

CoQ10 (Ubiquinol): The Most Evidence-Based IVF Supplement

CoQ10 is arguably the most important supplement for women preparing for IVF. Eggs have extraordinary mitochondrial energy requirements, and this energy demand is particularly intense during the final maturation stages that occur during ovarian stimulation.

As women age, mitochondrial CoQ10 levels decline — this is a primary driver of age-related egg quality decline. Supplementation with ubiquinol (the reduced, more bioavailable form) at doses of 400–600 mg/day has been shown in several clinical studies to improve ovarian response, egg quality, and embryo quality in women with poor ovarian reserve or previous poor response.

A landmark 2018 study in Aging found that CoQ10 supplementation improved meiotic spindle organisation in human oocytes from older women, directly addressing the chromosomal errors that cause age-related IVF failure.

Methylfolate: Essential from Day One

Methylfolate (active folate) is critical for DNA synthesis, cell division, and chromosomal integrity in the developing embryo. Adequate folate status before and at conception dramatically reduces risk of chromosomal errors and neural tube defects.

For IVF preparation, higher doses (600–1000 mcg/day of methylfolate) are commonly recommended to ensure optimal status ahead of the stimulation cycle. Standard folic acid may be inadequate in women with MTHFR variants — methylfolate bypasses this conversion step entirely.

Vitamin D: The Fertility Vitamin

Multiple studies specifically in IVF cohorts have found that women with sufficient vitamin D (25-OH vitamin D levels >50 nmol/L) have significantly better clinical pregnancy rates and live birth rates than deficient women. One large meta-analysis found that women with adequate vitamin D had 34% higher odds of clinical pregnancy per IVF cycle compared to deficient women.

Test your vitamin D level before your cycle and supplement to correct any deficiency — at least 2,000 IU daily for maintenance, potentially higher under medical supervision for correction.

Omega-3 Fatty Acids (DHA/EPA)

DHA is a structural component of oocyte membranes and plays roles in membrane fluidity and integrity during fertilisation. Several studies have found correlations between DHA levels and embryo quality. High-dose omega-3 supplementation (2–4g/day EPA+DHA) for 3+ months before IVF may improve oocyte and embryo quality.

Inositol for Ovarian Response

Myo-inositol (4g/day) has been shown in multiple RCTs to improve oocyte quality, reduce FSH requirements for stimulation, improve fertilisation rates, and increase clinical pregnancy rates in IVF. It is particularly beneficial for women with PCOS or poor responders. The mechanism involves improved insulin signalling in follicular cells and reduced oxidative stress in follicular fluid.

Antioxidant Support: Vitamin C, Vitamin E, and Alpha-Lipoic Acid

Oxidative stress in follicular fluid is associated with poorer egg quality and lower IVF success rates. A comprehensive antioxidant strategy — including vitamins C and E, alpha-lipoic acid, and selenium — helps protect developing oocytes from oxidative damage during the stimulation period.

IVF Preparation for Men: Optimising Sperm for ICSI or IVF

Even in IVF with intracytoplasmic sperm injection (ICSI), sperm quality matters beyond conventional semen analysis. Sperm DNA fragmentation, mitochondrial function, and antioxidant capacity all influence fertilisation rates, embryo development, and implantation success — and none of these are routinely measured in standard semen analysis.

CoQ10 for Sperm Energy and Motility

Sperm are highly motility-dependent cells. CoQ10 powers the mitochondrial ATP production in the sperm midpiece that drives flagellar movement. Clinical studies show CoQ10 supplementation (200–300 mg/day) improves sperm motility, concentration, and fertilisation rates.

Zinc and Selenium

These minerals are essential for sperm DNA integrity. Zinc is required for testosterone production and sperm formation; selenium forms part of glutathione peroxidase, a key antioxidant enzyme that protects sperm DNA from oxidative damage. Deficiency of either is associated with higher sperm DNA fragmentation rates.

L-carnitine

L-carnitine transports fatty acids into the mitochondrial matrix for energy production. Sperm mitochondria are particularly dependent on this mechanism. Supplementation (1–3g/day) has clinical evidence for improving sperm motility and reducing DNA fragmentation.

Vitamin C and E Complex

Antioxidant vitamins protect sperm from the reactive oxygen species that accumulate naturally in the reproductive tract. High-dose vitamin C (1g/day) + vitamin E (400 IU/day) combination has evidence for reducing sperm DNA fragmentation in studies of infertile men.

Conceive Plus Men's Fertility Support includes CoQ10, zinc, selenium, L-carnitine, and antioxidants in a comprehensive formula designed for IVF preparation. Available at conceiveplus.hk/collections/fertility-supplements.

Nutrition for IVF Preparation: The Evidence-Based Diet

A Mediterranean-style diet has the strongest evidence base for IVF outcomes. A 2018 study in Human Reproduction found that Greek women who closely adhered to a Mediterranean dietary pattern had a 65–68% higher probability of clinical pregnancy and live birth following IVF.

Key Mediterranean diet principles for IVF preparation:

• Abundant vegetables, particularly leafy greens, cruciferous vegetables, and tomatoes
• Legumes as a primary protein source (lentils, chickpeas, beans)
• Fatty fish (sardines, salmon, mackerel) 2–3x per week for omega-3s
• Olive oil as primary cooking fat
• Moderate whole grain intake
• Limited red and processed meat
• Minimal ultra-processed foods, refined sugar, and industrial seed oils
• Full-fat dairy (research suggests full-fat vs low-fat dairy may influence fertility outcomes)

Lifestyle Factors in IVF Preparation

Weight Optimisation

Both underweight (BMI <18.5) and overweight (BMI >25) status are associated with poorer IVF outcomes. Excess adipose tissue produces oestrogen and insulin-disrupting hormones that compromise follicular development; underweight status is associated with poor ovarian response and lower implantation rates. If your BMI is significantly outside the optimal range, nutritional and exercise support to move towards a healthier range over 3+ months before IVF is worthwhile.

Sleep

Melatonin produced during quality sleep has antioxidant properties specifically protective of oocytes — melatonin is concentrated in follicular fluid, where it protects developing eggs from oxidative stress. Women who sleep fewer than 7 hours per night have been shown to have lower IVF pregnancy rates in cohort studies. Prioritising 7–9 hours of quality sleep in the 90 days before egg retrieval is a genuinely evidence-based IVF preparation strategy.

Exercise

Moderate regular exercise improves insulin sensitivity, reduces inflammation, and supports hormonal balance — all beneficial for IVF. Vigorous exercise (>4 hours/week of vigorous activity) has been associated with lower IVF success in some studies, possibly through cortisol elevation and blood flow diversion from the reproductive system during intense activity. Aim for 30 minutes of moderate activity most days.

Smoking and Alcohol

Both partners should stop smoking before IVF. Smoking is associated with lower egg quality, poorer embryo development, reduced implantation rates, and higher miscarriage rates in IVF. The effect is dose-dependent and partially reversible — quitting months before the cycle matters.

Alcohol should be eliminated or minimised. Research specifically in IVF cohorts found that women consuming more than 4 drinks per week had significantly lower pregnancy rates. Both partners should abstain from the time supplementation begins.

Endocrine Disruptors

BPA, phthalates, PFAS, and other endocrine-disrupting chemicals (EDCs) are ubiquitous in plastics, personal care products, and food packaging. EDCs are linked to reduced egg quality, poorer embryo development, and disrupted hormonal signalling. For IVF preparation:

• Switch to glass or stainless steel food storage
• Avoid heating food in plastic containers
• Filter drinking water (reverse osmosis or activated carbon)
• Choose phthalate-free personal care products

Mental Health and IVF Preparation

IVF is associated with significant psychological burden — anticipatory anxiety, grief from previous losses, relationship strain, and the particular stress of the clinical process itself. Mental health preparation is as important as physical preparation.

Clinically-evidenced approaches for IVF psychological preparation:

• Cognitive-behavioural therapy (CBT) adapted for fertility
• Mindfulness-based stress reduction (MBSR) — has shown improved IVF outcomes in some studies
• Fertility counselling with a specialist therapist
• Peer support groups (in-person or online fertility communities)
• Open communication with partner about expectations, worst-case scenarios, and boundaries

Questions to Ask Your Clinic Before IVF

Becoming an informed participant in your IVF treatment improves both outcomes and experience:

• What stimulation protocol do you recommend for my profile, and why?
• Will you measure my anti-Müllerian hormone (AMH) and antral follicle count before starting?
• Do you recommend preimplantation genetic testing (PGT-A) for our situation?
• What are your lab's fertilisation, blastocyst development, and clinical pregnancy rates for my age group?
• What is your freeze-all vs fresh transfer policy?
• What luteal phase support do you use after transfer?
• Are there supplements or lifestyle factors you recommend I address before the cycle?

FAQ: IVF Preparation

Q: How far in advance should I start IVF preparation?
A: At minimum 3 months before the cycle begins — aligned with the 90-day window for both egg and sperm development. Starting 6 months ahead is even better.

Q: Can I take all these supplements simultaneously?
A: Yes, the supplements recommended for IVF preparation are generally complementary and safe to combine. Use a comprehensive fertility supplement that includes most key ingredients, supplementing with additional CoQ10 as needed. Always inform your fertility clinic of everything you're taking.

Q: Is acupuncture helpful for IVF?
A: Evidence is mixed. Some studies show modest benefits on IVF outcomes; others show no effect. It is generally safe, may help with stress management, and is commonly used alongside IVF in Hong Kong and across Asia. Many fertility specialists support it as an adjunct.

Q: Should I do PGT-A (preimplantation genetic testing) for my IVF cycle?
A: PGT-A is recommended for women over 37, those with recurrent pregnancy loss, repeated implantation failure, or prior aneuploid embryos. The decision involves balancing the cost and embryo biopsy impact against the benefit of identifying chromosomally normal embryos. Discuss with your specialist.

Q: Can I continue to work during IVF treatment?
A: Most women continue working through IVF, including monitoring appointments and retrieval. The retrieval procedure typically requires 1–2 days of rest. Embryo transfer requires minimal recovery. Stress reduction is beneficial — if your work is extremely high-stress, managing that element specifically is worthwhile.

Q: How much does CoQ10 dose matter for IVF?
A: Dose matters significantly. Studies showing benefit typically used 400–600 mg/day of CoQ10 or 200–400 mg/day of ubiquinol. Lower doses (30–60 mg in many multivitamins) are likely insufficient for meaningful oocyte mitochondrial support.

Q: What should I stop taking before egg retrieval?
A: Your clinic will advise specifically. Generally, omega-3 supplements are sometimes paused 1 week before retrieval due to theoretical anticoagulant effects. Blood-thinning herbs should be stopped. Your fertility clinic's guidance takes precedence over general recommendations.

Q: Is embryo quality entirely determined by age, or can supplements help?
A: Age is the dominant factor — chromosomal aneuploidy rates in eggs increase significantly with age. But within any age group, there is meaningful variation in egg quality that is influenced by nutritional status, oxidative stress, mitochondrial function, and lifestyle factors — all modifiable by preparation.

Q: Where can I find Conceive Plus supplements in Hong Kong?
A: Conceive Plus is available directly at conceiveplus.hk/collections/fertility-supplements with delivery throughout Hong Kong.
