Lifestyle and Fertility: Habits That Help or Hurt
Lifestyle and Fertility: Habits That Help or Hurt
When couples struggle to conceive, they often focus on medical treatments. But lifestyle factors can significantly influence both natural fertility and the success of treatments like IVF.
Habits That HELP Fertility
Maintain a healthy weight: BMI between 19-25 is optimal. Both underweight and overweight women may have irregular ovulation. For men, obesity is linked to lower sperm count and quality.
Regular moderate exercise: 30 minutes of moderate activity most days improves blood flow to reproductive organs and reduces stress. Walking, swimming, and yoga are excellent choices.
Quality sleep: 7-9 hours per night. Poor sleep disrupts hormone production, including those essential for ovulation and sperm production.
Stress management: Chronic stress elevates cortisol, which can suppress reproductive hormones. Consider meditation, deep breathing, counselling, or simply activities that bring you joy.
Hydration: 2-3 litres of water daily supports cervical mucus production and overall cellular health.
Antioxidant-rich diet: Colourful fruits and vegetables, nuts, and seeds protect eggs and sperm from oxidative damage.
Habits That HURT Fertility
Smoking: Reduces ovarian reserve in women and damages sperm DNA in men. Smokers reach menopause 1-4 years earlier. Quitting can improve outcomes significantly.
Excessive alcohol: More than 7 drinks per week for women or 14 for men is associated with decreased fertility. During treatment, abstinence is recommended.
Excessive caffeine: More than 300mg daily (about 2-3 cups of coffee) is associated with longer time to conception and increased miscarriage risk.
Recreational drugs: Cannabis, cocaine, and anabolic steroids all negatively impact fertility in both sexes.
Excessive heat (men): Hot baths, saunas, tight underwear, and laptops on the lap can raise testicular temperature and impair sperm production.
Environmental toxins: BPA in plastics, pesticides, and certain household chemicals can act as endocrine disruptors.
Extreme exercise: While moderate exercise helps, excessive intense training (marathon running, extreme CrossFit) can suppress ovulation in women.
The 90-Day Rule
Both eggs and sperm take approximately 90 days to mature. This means lifestyle changes you make today will impact the eggs and sperm available 3 months from now. Start early.
For Couples Going Through IVF
During an IVF cycle:
- Follow your clinic's specific guidelines
- Avoid alcohol entirely
- Reduce caffeine to one cup daily
- Continue gentle exercise but avoid high-impact activities
- Prioritise sleep and stress reduction
- Take prescribed supplements consistently
Small Changes, Big Impact
You don't need to overhaul your entire life overnight. Start with one or two changes and build from there. Even modest improvements in lifestyle can make a meaningful difference in your fertility journey.
