IVF Preparation: A Complete Guide to Getting Your Body Ready for Treatment

Deciding to pursue IVF (in vitro fertilisation) is a significant, hopeful, and often emotionally complex step. While much of what happens in an IVF cycle is in the hands of your clinical team, there is a meaningful amount you can do to optimise your body's readiness — and potentially improve your outcomes. This comprehensive IVF preparation guide covers the nutritional, lifestyle, and supplementation strategies most supported by current evidence, along with practical guidance on what to expect.

Conceive Plus supports couples through every stage of the fertility journey, including IVF preparation. Our evidence-based products and education are designed for real people navigating real challenges — not platitudes, but practical science. Here is what the research says about maximising your IVF readiness.

Why IVF Preparation Matters

IVF outcomes are influenced by multiple factors, some fixed (age, ovarian reserve, genetic factors) and some modifiable. Research consistently shows that nutritional status, body weight, oxidative stress levels, and lifestyle factors measurably affect egg quality, embryo development, endometrial receptivity, and implantation success.

Because egg development (folliculogenesis) takes approximately 90 days, and sperm production (spermatogenesis) also takes approximately 90 days, the ideal IVF preparation window begins 3 months before your estimated egg retrieval date. Changes made during this window have the potential to influence the eggs and sperm that will be used in your cycle.

Preparation is not about perfection — it's about shifting your biological environment to give your best possible eggs and sperm the best possible environment for fertilisation, development, and implantation.

The IVF Preparation Timeline: 3 Months Out

Begin as early as possible — ideally 3 months before your planned egg retrieval. This timeline aligns with the biological windows for egg and sperm development.

3 months before retrieval:

• Start or optimise all key supplements (see below)
• Begin or intensify dietary improvements
• Get baseline blood tests (vitamin D, folate, ferritin/iron, thyroid function, AMH if not recently done)
• Both partners address lifestyle factors: smoking cessation, alcohol reduction, weight optimisation if needed

1–2 months before retrieval:

• All supplements should be consistently established
• Book acupuncture consultation if planned (see below)
• Review semen analysis for male partner — address findings with urologist if needed
• Confirm with IVF clinic what they want you to take/avoid during stimulation

The month before retrieval:

• Prioritise sleep, stress management, and gentle exercise
• Eliminate alcohol completely
• Confirm supplement plan with IVF team (some supplements may be discontinued or continued through stimulation per clinic protocol)

Supplements for IVF Preparation: The Evidence

CoQ10 (Coenzyme Q10): The Premier Egg Quality Supplement

CoQ10 is the most studied and evidence-backed supplement for IVF egg quality preparation. Here's why: mitochondria generate the ATP energy that powers every stage of egg development — from folliculogenesis through meiosis to fertilisation. CoQ10 is essential for mitochondrial electron transport, and its levels in oocytes (eggs) decline significantly with age.

A landmark 2018 randomised controlled trial found that women over 35 who supplemented with CoQ10 (600mg/day as ubiquinol) for 60 days before IVF had significantly higher numbers of mature (MII) eggs, higher fertilisation rates, and higher rates of top-quality embryos compared to placebo. A 2020 meta-analysis confirmed that CoQ10 supplementation significantly improved clinical pregnancy rates in IVF patients.

Recommended dose for IVF preparation: 400–600mg/day of ubiquinol (the reduced, more bioavailable form) or 600mg–1,200mg/day of ubiquinone. Begin 2–3 months before retrieval. Discuss with your IVF team whether to continue during stimulation — most protocols allow it through the stimulation phase.

DHEA: For Poor Responders and Diminished Ovarian Reserve

DHEA (dehydroepiandrosterone) has emerged as a significant supplement specifically for women with diminished ovarian reserve (DOR) or poor response to ovarian stimulation. DHEA is an androgen precursor — it converts to testosterone and oestrogen — and follicle development in the early stages requires androgen stimulation to allow follicles to respond to FSH.

Multiple studies, including a 2010 randomised controlled trial, found that DHEA supplementation for 4–12 weeks before IVF significantly improved egg number, fertilisation rates, and pregnancy rates in poor responders. Several subsequent studies have confirmed these findings. The benefit appears greatest in women under 40 with DOR, and in women with premature ovarian insufficiency.

Recommended protocol: 25–75mg/day for 4–12 weeks before retrieval. This is one supplement that should only be started after discussing with your IVF specialist, as it is not appropriate for all patients and can interfere with testing in some contexts.

Folate/Methylfolate: Non-Negotiable for IVF

Folate is essential for DNA synthesis and cell division — two processes that are occurring at extraordinary rates in the fertilised egg and early embryo. It also reduces sperm DNA fragmentation (important for the male partner). Begin folic acid or methylfolate (400–800µg/day) at least 3 months before intended retrieval, and continue through pregnancy.

Women with the MTHFR gene polymorphism should use methylfolate (5-MTHF) rather than folic acid, as they cannot efficiently convert folic acid to its active form. Ask your doctor about MTHFR testing if you haven't been tested, particularly if you have a history of recurrent miscarriage.

Vitamin D: Essential for Endometrial Receptivity

A 2014 meta-analysis of five studies found that IVF patients with adequate vitamin D levels were significantly more likely to achieve a live birth than those with vitamin D deficiency. Vitamin D receptors are found on endometrial cells, and vitamin D plays roles in immune tolerance of the embryo — one of the mechanisms underlying implantation.

Test your 25-OH vitamin D level 3 months before retrieval and supplement to achieve a level of 75–100nmol/L. This typically requires 1,000–2,000IU/day for moderately deficient individuals in temperate climates.

Omega-3 Fatty Acids: Supporting Egg Quality and Implantation

DHA is essential for oocyte plasma membrane fluidity and integrity. Several studies have found that higher omega-3 fatty acid intake is associated with better egg quality, higher fertilisation rates, and better embryo development in IVF. Omega-3s also have anti-inflammatory properties that may support endometrial receptivity.

Recommended: 1–2g EPA+DHA per day from fish oil or algae oil, beginning 3 months before retrieval.

Melatonin: The Emerging IVF Supplement

Melatonin — typically known as a sleep hormone — is produced in follicular fluid surrounding developing eggs, where it acts as a powerful antioxidant. Women undergoing IVF have been found to have lower follicular fluid melatonin concentrations than fertile controls. A randomised trial found that melatonin supplementation (3mg at bedtime) significantly improved fertilisation rates and the number of high-quality embryos in poor prognosis IVF patients.

Melatonin for IVF preparation is typically used at 2–3mg at bedtime for 1–2 months before retrieval. Discuss with your IVF team before starting, as protocols vary and melatonin can affect sleep architecture at higher doses.

Male IVF Preparation: Don't Neglect the Sperm

Even with IVF — where sperm and egg are brought together in the laboratory — sperm quality has a profound impact on outcomes. High sperm DNA fragmentation rates are associated with lower fertilisation rates, poorer embryo quality, and higher miscarriage rates even after successful fertilisation.

Male IVF preparation should include:

• Antioxidants (Vitamin C 1,000mg, Vitamin E 400IU, Selenium 100µg) to reduce oxidative stress and sperm DNA fragmentation
• Zinc (25–50mg/day) for testosterone and spermatogenesis
• Folate (400–800µg/day) to reduce sperm DNA fragmentation
• CoQ10 (200–400mg/day) for sperm mitochondrial function and motility
• DHA (1–2g/day) for sperm membrane integrity

Begin 3 months before intended egg retrieval. Conceive Plus Men's Fertility Support provides the core of this evidence-based stack.

Diet and Weight for IVF Preparation

A Mediterranean-style diet is the most evidence-backed dietary approach for IVF preparation — it has been directly associated with higher clinical pregnancy and live birth rates in IVF populations. Key elements: abundant vegetables and fruit, legumes, whole grains, olive oil, nuts, fatty fish, limited red meat and processed food.

Body weight significantly affects IVF outcomes. Women with a BMI above 30 have lower egg retrieval numbers, lower fertilisation rates, lower implantation rates, and higher miscarriage rates in IVF cycles. Even modest weight loss (5–10% of body weight) before beginning treatment meaningfully improves outcomes in overweight women.

Lifestyle Factors in IVF Preparation

Sleep

Chronic sleep deprivation suppresses melatonin production (which, as noted, is produced in follicular fluid) and disrupts circadian regulation of reproductive hormones including FSH, LH, oestrogen, and progesterone. Prioritising 7–9 hours of quality sleep per night is an often-undervalued component of IVF preparation.

Exercise

Moderate-intensity exercise (30 minutes most days) supports healthy weight, reduces stress, improves insulin sensitivity, and is associated with better IVF outcomes in general population studies. High-intensity or excessive exercise, however, may impair ovarian function and is generally best avoided in the month before and during stimulation. Gentle walking, yoga, swimming, and Pilates are ideal during the stimulation phase.

Stress Management

Chronic psychological stress activates the hypothalamic-pituitary-adrenal (HPA) axis and suppresses the hypothalamic-pituitary-ovarian (HPO) axis — the system controlling ovulation and reproductive hormone release. While a single stressed cycle is unlikely to significantly impact IVF outcomes, chronic stress may. Evidence-based stress management tools relevant to IVF preparation include mindfulness-based stress reduction (MBSR), cognitive behavioural therapy (CBT), acupuncture, and peer support groups for people undergoing fertility treatment.

Alcohol and Smoking

Both are associated with significantly worse IVF outcomes. Smoking reduces ovarian reserve, impairs egg quality, and lowers pregnancy rates per cycle. Studies suggest IVF patients who smoke need twice as many cycles to achieve a live birth compared to non-smokers. Eliminate both completely before beginning IVF preparation.

FAQ: IVF Preparation

Q: How early should I start IVF preparation?
A: Ideally 3 months before your planned egg retrieval, to align with the oocyte development window. However, even 4–6 weeks of optimised nutrition and supplementation can be beneficial. Start as early as possible.

Q: Does acupuncture help with IVF?
A: The evidence is mixed — some studies show benefit for stress reduction and uterine blood flow; meta-analyses of acupuncture during embryo transfer have been inconclusive. It is low-risk and may be beneficial; if you're interested, starting a few weeks before retrieval is most common.

Q: Should I continue supplements during IVF stimulation?
A: Discuss with your IVF team. Most will support continuing folate, vitamin D, CoQ10, and omega-3 through stimulation. Some may ask you to stop certain supplements (particularly those with blood-thinning properties) before retrieval. Always follow clinic protocol.

Q: Can CoQ10 really improve egg quality?
A: For women over 35 or with diminished ovarian reserve, the randomised controlled evidence is reasonably strong. Results in younger women with good ovarian reserve are less dramatic. The benefit-to-risk profile strongly favours supplementation in most IVF candidates.

Q: How does stress affect IVF outcomes?
A: Chronic severe stress may suppress ovarian function and impair implantation through hormonal pathways. Acute stress around a specific cycle likely has limited impact on egg quality (which was determined 3 months prior). Managing stress is important for wellbeing and may have modest outcome benefits.

Q: Is there anything I should avoid during IVF preparation?
A: Alcohol, smoking, excessive caffeine, trans fats, and extreme caloric restriction. Also avoid over-the-counter NSAIDs (ibuprofen, aspirin) unless prescribed by your IVF team, as they may affect ovulation and implantation.

Q: Does my partner need to prepare differently for IVF?
A: Yes — male IVF preparation focuses on antioxidant-rich supplements (zinc, selenium, vitamin C, E, CoQ10, folate), healthy diet, exercise, and eliminating alcohol and smoking. Sperm quality directly affects fertilisation rates and embryo quality even in IVF cycles.

Q: Are Conceive Plus supplements safe to use during IVF preparation?
A: Conceive Plus fertility supplements are formulated with nutrients at evidence-based, safe doses for preconception use. Always inform your IVF clinic of all supplements you are taking so they can advise on any specific protocol adjustments.
