BMI is a measure that combines height and weight into a single number and is a good indicator of total body fat. Women who start pregnancy with a normal BMI, compared to overweight or obese women, have better maternal and infant outcomes. Being severely underweight or overweight can interrupt normal menstrual cycles, impact ovulation or stop it all together. It’s therefore important to maintain a healthy lifestyle and BMI for your fertility health. Research also indicates that overweight men aren’t as fertile as their healthy weight counterparts, with excess weight lowering sperm production.
