Weight

How it can impact your fertility

  • Being overweight or underweight can negatively affect your fertility. Keeping your weight within the optimal BMI range of 20-25 is the single most important lifestyle factor that can affect your fertility. 
  • women and men with obesity [body mass index (BMI) ≥ 30 kg/m2] have a higher risk of infertility. This risk is extended to women who are underweight (BMI <20 kg/m2). 
  • Weight also has an impact on male fertility. Men with a high BMI produce fewer normal, motile sperm in the ejaculate as a result of the ‘heat’ effect of that tummy, so women who start a diet and exercise routine to boost their ‘fertility fitness’ should encourage their partners to join in.
