A high body-mass index (BMI) combined with a sedentary lifestyle decreases the likelihood of natural conception. Dutch researchers randomized 574 infertile, obese women to a six month lifestyle program of lowered calories and increased physical activity followed by infertility treatment. Those in this group experienced 10% higher natural conception than the control group which received infertility treatments immediately.
PositiveTip: Modest weight loss and more exercise can increase the chances of natural conception in young infertile, obese women.
