Can Lifestyle Factors Affect IVF Outcomes?
Many lifestyle habits are associated with reproductive health and may support your overall wellbeing during fertility treatment. For example, maintaining a healthy weight, getting adequate sleep and avoiding smoking are all part of supporting your health throughout IVF treatment. At the same time, it is important to remember that many aspects of IVF outcomes remain beyond your control.
Rather than focusing on a single lifestyle factor, consider how your daily habits work together to support your health before and during IVF. The following sections outline practical, evidence-based steps that may help you prepare for treatment.
How Nutrition and Maintaining a Healthy Weight Affect IVF Outcomes
Good nutrition helps provide your body with the nutrients needed to support your health throughout fertility treatment. While there is no single diet proven to guarantee IVF success, maintaining a balanced diet and a healthy weight may help support your general health before treatment and pregnancy.
Rather than following restrictive diets or searching for foods that claim to "boost fertility", focus on consistent healthy eating habits such as:
- Eating a variety of vegetables, fruits, whole grains and lean proteins
- Including healthy fats such as those found in nuts, seeds and oily fish
- Staying well hydrated throughout the day
- Limiting highly processed foods and foods high in added sugar
Maintaining a healthy weight may also be beneficial before starting IVF. Being underweight or overweight can affect hormone regulation and may influence how your body responds to fertility medications. If weight management is recommended, gradual and sustainable changes are generally preferred over rapid weight loss or restrictive eating plans.
Some supplements, such as folic acid, are routinely recommended when trying to conceive. However, not all fertility supplements have strong evidence supporting their use, and taking excessive amounts of certain vitamins or herbal products may not be beneficial. Before starting any supplements, speak with your fertility specialist to ensure they are appropriate for your treatment plan.
How Sleep, Stress and Emotional Wellbeing Affect IVF Outcomes
Undergoing IVF can be physically and emotionally demanding. While stress alone has not been shown to cause IVF treatment to fail, prioritising good sleep and looking after your emotional wellbeing may help you feel better prepared to cope with each stage of treatment.
Prioritise Good Sleep
Quality sleep plays an important role in supporting your overall health, hormone regulation and recovery. Although occasional sleep disruption is common during IVF, establishing healthy sleep habits may help you feel better rested and cope with treatment more comfortably.
Some simple ways to support better sleep include:
- Keeping a consistent sleep and wake schedule
- Limiting screen time before bed
- Creating a comfortable and quiet sleeping environment
- Avoiding caffeine late in the day where possible
Manage Stress in Healthy Ways
It is natural to experience anxiety, uncertainty or disappointment during fertility treatment. Rather than trying to eliminate stress completely, focus on practical strategies that can make it easier to cope throughout treatment in a way that works for you.
These may include:
- Regular light exercise, such as walking or yoga
- Mindfulness, meditation or breathing exercises
- Speaking openly with your partner, family or trusted friends
- Joining a fertility support group or seeking professional counselling if needed
Remember that experiencing stress or difficult emotions does not mean your IVF treatment is less likely to succeed. If you find that anxiety or emotional distress is becoming overwhelming, let your fertility specialist know so that your care team can recommend additional support or refer you to appropriate resources.
How Exercise, Smoking, Alcohol and Caffeine Affect IVF Outcomes
Stay Physically Active
Avoid Smoking and Limit Alcohol
Smoking is associated with reduced fertility in both women and men and may affect egg quality, sperm quality and overall reproductive health. If you smoke, stopping before IVF is one of the most beneficial lifestyle changes you can make for your health.
Alcohol is also generally discouraged when trying to conceive and during IVF treatment. Your fertility specialist can advise you on appropriate recommendations based on your individual circumstances.
Be Mindful of Caffeine Intake
Moderate caffeine intake is generally considered acceptable for most people trying to conceive. However, excessive caffeine consumption is not recommended during fertility treatment or pregnancy planning.
If you regularly consume coffee, tea or caffeinated beverages, your fertility specialist can advise you on an appropriate daily intake as part of your overall IVF care plan.
Why Both Partners' Health Matters During IVF
Although IVF treatment primarily involves the woman, the health of both partners can influence fertility and treatment planning. Male fertility factors contribute to a significant proportion of infertility cases, making it beneficial for couples to adopt healthy habits together before treatment begins.
Preparing together may include:
- Supporting the woman's health by maintaining healthy lifestyle habits, attending recommended appointments and managing any existing medical conditions before and during IVF.
- Supporting the man's reproductive health by maintaining a healthy weight, avoiding smoking, limiting alcohol consumption and discussing any medications or chronic medical conditions with a healthcare professional.
- Attending fertility consultations together, where possible, to better understand the treatment process, ask questions and make informed decisions as a couple.
- Supporting one another emotionally throughout the IVF journey, recognising that fertility treatment can affect both partners and that open communication may help couples navigate each stage with greater confidence.
Preparing for IVF with Your Fertility Specialist
Lifestyle changes are only one part of getting ready for IVF. Before treatment begins, your fertility specialist will assess your overall health, review any existing medical conditions and recommend steps to help ensure you are ready for each stage of the IVF process.
Your pre-treatment consultation may include:
- Reviewing your medical history and any previous fertility investigations or treatments.
- Discussing your current medications and supplements to determine whether any adjustments are needed before treatment begins.
- Managing existing medical conditions, such as diabetes, thyroid disorders or hypertension, to optimise your health before IVF.
- Providing personalised lifestyle recommendations based on your medical history, fertility diagnosis and treatment goals.
- Explaining what to expect during IVF, including the treatment timeline, medications and monitoring required throughout your cycle.
Every fertility journey is different. Working closely with your fertility specialist allows your treatment plan to be tailored to your individual circumstances, helping you understand your treatment options and make informed decisions throughout your fertility journey.
