Obese Men Have Less Semen, More Sperm Abnormalities, And Should Lose Weight Before Trying For A Baby

“Obese men should consider losing weight if they want to have children, a scientist told the 24th annual conference of the European Society of Human Reproduction and Embryology. Dr. A Ghiyath Shayeb, from the University of Aberdeen, Aberdeen, UK, said that his research had shown that men with a higher body mass index (BMI) had lower volumes of seminal fluid and a higher proportion of abnormal sperm. Dr. Shayeb and colleagues looked at the results of seminal fluid analysis in 5316 men attending Aberdeen Fertility Centre with their partners for difficulties in conceiving. 2037 of these men had complete data on their BMIs. ‘We felt that it was possible that male overweight might contribute to fertility problems,’ he said, ‘particularly since it is a known risk factor for problems in conceiving among women.’ ‘Our findings were quite independent of any other factors,’ he said, ‘and seem to suggest that men who are trying for a baby with their partners, should first try to achieve an ideal body weight. This is in addition to the benefit of a healthy BMI for their general well being. ‘Adopting a healthy lifestyle, a balanced diet, and regular exercise will, in the vast majority of cases, lead to a normal BMI. We are pleased to be able to add improved semen quality to the long list of benefits that we know are the result of an optimal body weight.’”
