While medical intervention is sometimes necessary, there are many evidence-based lifestyle changes that can meaningfully improve fertility for both men and women. These changes not only enhance your chances of natural conception but also improve outcomes if you need fertility treatment.
Nutrition and Diet
- Eat a balanced, whole-food diet: Focus on fruits, vegetables, whole grains, lean proteins, and healthy fats. The Mediterranean diet has been shown to improve fertility outcomes.
- Include antioxidant-rich foods: Berries, nuts, leafy greens, and colourful vegetables help combat oxidative stress that damages eggs and sperm.
- Choose healthy fats: Omega-3 fatty acids (found in fish, walnuts, and flaxseeds) support hormone production and reduce inflammation.
- Limit processed foods and sugar: These can worsen insulin resistance, particularly in women with PCOS.
- Ensure adequate folic acid: Essential for early pregnancy. Begin supplementation at least 3 months before trying to conceive.
Exercise
Regular moderate exercise improves insulin sensitivity, helps maintain a healthy weight, reduces stress, and supports hormonal balance. Aim for 150 minutes of moderate activity per week – brisk walking, swimming, yoga, or cycling are excellent choices. However, avoid excessive high-intensity exercise, which can disrupt ovulation in women.
Weight Management
Both being overweight and underweight can impair fertility. For women, a BMI between 19 and 25 is associated with the best fertility outcomes. Even modest weight changes – losing or gaining 5–10% of body weight – can restore ovulation and improve conception rates.
Avoid Harmful Substances
- Quit smoking: Smoking damages eggs, sperm, and reduces IVF success rates.
- Limit alcohol: Heavy drinking is associated with reduced fertility in both men and women. Moderate consumption or abstinence is recommended when trying to conceive.
- Reduce caffeine: Limit caffeine to 200 mg per day (about one cup of coffee).
- Avoid recreational drugs: Cannabis, cocaine, and other substances negatively affect sperm quality and ovulation.
Stress Management
Chronic stress can disrupt the hormonal signals needed for ovulation and sperm production. While the relationship between stress and infertility is complex, managing stress through mindfulness, yoga, counselling, or regular relaxation practices can support overall reproductive health and improve the experience of trying to conceive.
Sleep
Quality sleep is essential for hormonal regulation. Aim for 7–8 hours of uninterrupted sleep per night. Poor sleep patterns have been linked to irregular menstrual cycles and reduced sperm quality.
These lifestyle changes are simple, cost-free, and can have a meaningful impact on your fertility journey. Whether you are trying naturally or preparing for treatment, building a healthy foundation gives you the best possible start.
