When you are investing so much, emotionally, physically, and financially, in IVF treatment, it is natural to want to do everything in your power to give yourself the best possible chance of success. While there are no guarantees in fertility treatment, research has identified several factors that can meaningfully influence your outcomes. Here are ten evidence-based strategies that may help improve your IVF success rate.
1. Optimize Your Weight Before Starting Treatment
Body weight plays a significant role in reproductive health and IVF outcomes. Research consistently shows that both underweight and overweight individuals may experience reduced fertility and lower IVF success rates.
A body mass index (BMI) between 19 and 25 is generally associated with the best IVF outcomes. Being significantly overweight can affect hormone levels, reduce egg quality, and impair endometrial receptivity. Being significantly underweight can disrupt ovulation and reduce the uterine lining's ability to support implantation.
If your BMI falls outside the optimal range, even modest changes can make a difference. Studies have shown that losing just 5 to 10% of body weight in overweight patients can improve ovarian response, egg quality, and pregnancy rates. This is not about achieving a perfect number on the scale; it is about moving your body toward a healthier baseline before treatment begins.
Give yourself time. Ideally, work toward a healthier weight three to six months before starting your IVF cycle, as it takes approximately three months for eggs to develop from their primordial stage to maturity.
2. Adopt a Mediterranean-Style Diet
Among all dietary patterns studied in relation to fertility, the Mediterranean diet has the strongest evidence base. This eating pattern emphasizes fruits, vegetables, whole grains, legumes, nuts, olive oil, and fish while limiting red meat, processed foods, and added sugars.
A 2024 literature review examining the role of the Mediterranean diet in assisted reproduction found that higher adherence to this dietary pattern was associated with improved clinical pregnancy rates and live birth rates across several studies. One study found that women who closely followed a Mediterranean diet had nearly twice the likelihood of achieving a clinical pregnancy (RR 1.98) and more than twice the likelihood of a live birth (RR 2.64) compared to those with low adherence.
The mechanism likely involves the anti-inflammatory and antioxidant properties of the foods in this diet. The omega-3 fatty acids in fish, the polyphenols in olive oil and vegetables, and the folate in leafy greens all contribute to a healthier reproductive environment. You do not need to follow the diet perfectly. Even increasing your intake of vegetables, switching to olive oil, and reducing processed food consumption can move the needle.
3. Stop Smoking and Limit Alcohol
If there is one lifestyle change that has unequivocal evidence behind it, it is quitting smoking. Smoking is linked to accelerated loss of eggs, reduced ovarian reserve, lower fertilization rates, and higher miscarriage rates. Studies have shown that smokers may need nearly twice as many IVF cycles to achieve pregnancy as non-smokers. Smoking also ages the ovaries, meaning a 35-year-old smoker may have ovarian function closer to that of a 40-year-old non-smoker.
The good news is that some of the damage from smoking is at least partially reversible. Quitting at least three months before starting IVF can improve outcomes, though quitting earlier is better.
Alcohol presents a more nuanced picture, but the general consensus is to minimize consumption during IVF treatment. A study published in Obstetrics and Gynecology found that women who drank four or more alcoholic beverages per week had a 16% lower chance of IVF success compared to those who drank fewer than four drinks per week. During the stimulation phase and after embryo transfer, most fertility specialists recommend abstaining entirely.
4. Take the Right Supplements
Certain supplements have evidence supporting their use during IVF, though they should always be discussed with your doctor:
Coenzyme Q10 (CoQ10)
CoQ10 is an antioxidant that plays a critical role in cellular energy production within the mitochondria. A 2024 systematic review and meta-analysis found that CoQ10 supplementation improved oocyte retrieval numbers and pregnancy rates in women with diminished ovarian reserve (DOR) and poor ovarian response. Typical recommended doses range from 200 to 600 mg per day, started at least two to three months before treatment.
Vitamin D
Vitamin D deficiency is common and has been associated with lower IVF success rates. While the evidence is not yet definitive enough to prove causation, maintaining adequate vitamin D levels (above 30 ng/mL) is generally recommended. A simple blood test can check your levels, and supplementation is safe and inexpensive.
Folic Acid and Prenatal Vitamins
Taking a prenatal vitamin with at least 400 micrograms of folic acid is standard medical advice for anyone trying to conceive, whether naturally or through IVF. Folic acid is critical for preventing neural tube defects and may also support egg quality and endometrial health.
DHEA
Dehydroepiandrosterone (DHEA) has shown benefit for women with diminished ovarian reserve. Medical studies have found that DHEA supplementation can improve egg yield and quality in women with DOR or those who responded poorly in previous cycles. However, DHEA is not appropriate for all patients and should only be taken under medical supervision.
5. Manage Your Stress
The relationship between stress and IVF outcomes is complex, and the last thing you need is to feel stressed about being stressed. Research does not definitively prove that stress causes IVF failure. However, chronic stress can affect hormonal balance, sleep quality, and overall well-being, all of which matter during treatment.
What the evidence does support is the value of active stress management. A comprehensive meta-analysis found that acupuncture performed around the time of embryo transfer was associated with approximately 19% higher clinical pregnancy rates compared to controls. Whether the benefit comes from acupuncture itself or from the dedicated relaxation time it provides is still debated, but the association is meaningful.
Other evidence-based approaches to stress management during IVF include:
- Mindfulness meditation: Even 10 to 15 minutes daily has been shown to reduce anxiety and improve quality of life during IVF.
- Cognitive behavioral therapy (CBT): Working with a therapist who specializes in fertility can provide concrete tools for managing the emotional challenges of treatment.
- Gentle exercise: Activities like walking, yoga, and swimming can reduce cortisol levels and improve mood without the intensity that might affect fertility.
- Support groups: Connecting with others who understand what you are going through can reduce feelings of isolation and provide practical coping strategies.
6. Choose the Right Clinic and Doctor
Not all fertility clinics are created equal, and the differences can affect your outcomes. When evaluating clinics, look at:
- Success rates for your age group and diagnosis: The CDC and SART publish clinic-specific data, but remember to compare rates for patients similar to you rather than overall averages.
- Laboratory quality: The embryology lab is where your eggs are fertilized, embryos are cultured, and freezing takes place. Ask about the lab's technologies, success rates, and quality control measures.
- Doctor experience: Ask whether the doctor has experience treating patients with your specific condition.
- Communication: A clinic that communicates clearly, returns calls promptly, and makes you feel heard can reduce stress and help you make better treatment decisions.
7. Be Open to Protocol Adjustments
If your first IVF cycle does not succeed or produces a suboptimal response, do not assume the same approach will be repeated. A good fertility doctor will analyze every aspect of your previous cycle, from stimulation response to egg quality to embryo development, and adjust the protocol accordingly.
Potential adjustments include changing medication types or dosages, using a different stimulation protocol (long agonist, antagonist, mini-IVF, or microdose flare), adding adjunct therapies like growth hormone or letrozole, switching from a fresh transfer to a freeze-all strategy, or adjusting the timing of the trigger shot.
Each cycle provides valuable data, and the willingness to adapt based on that data can significantly improve subsequent outcomes.
8. Consider Elective Single Embryo Transfer
While it might seem logical that transferring two embryos would double your chances, the reality is more nuanced. Transferring multiple embryos does increase the chance of pregnancy per cycle, but it also significantly increases the risk of twin or higher-order multiples, which carry substantially higher risks of preterm birth, low birth weight, gestational diabetes, preeclampsia, and other complications.
For patients under 38 with good-quality embryos, elective single embryo transfer (eSET) achieves pregnancy rates comparable to double embryo transfer while dramatically reducing the risk of multiples. The cumulative success rate (success over multiple single transfers) is often comparable to or better than a single double transfer.
Discuss with your doctor whether eSET is appropriate for your situation. In many cases, it offers the best balance of success and safety.
9. Do Not Give Up Too Soon
IVF success rates are often discussed on a per-cycle basis, but what really matters is your cumulative chance of success over multiple cycles. The data here is genuinely encouraging.
UK research involving over 150,000 women found a cumulative prognosis-adjusted live birth rate of 65.3% after six IVF cycles. For women under 35, the cumulative rate is even higher, reaching approximately 80% after three cycles. Even for women aged 40 to 42, the cumulative rate after six cycles was 31.5%, a meaningful chance given the challenges of later reproductive age.
Each cycle provides an opportunity for your doctor to learn and refine the approach. If you have the emotional and financial capacity to try again, the odds are often in your favor over multiple attempts.
10. Take Care of Your Whole Self
This final point encompasses all the others but goes beyond them. IVF is a marathon, not a sprint, and taking care of your overall well-being is both a strategy for success and a way to preserve your mental health through the process.
- Sleep: Aim for seven to nine hours per night. Poor sleep has been associated with reduced fertility and may affect hormonal regulation.
- Movement: Maintain regular, moderate physical activity. Walking 30 minutes a day, gentle yoga, or swimming are excellent choices. Avoid high-intensity exercise during stimulation and after transfer.
- Connection: Lean on your partner, friends, or support community. Do not try to carry the burden alone.
- Boundaries: It is okay to decline baby showers, mute social media accounts, or tell well-meaning friends you need a break from fertility conversations.
- Joy: Do not let IVF consume your entire identity. Continue to do things that bring you pleasure and remind you that life is about more than treatment cycles.
