Obese men must think about loosing weight now once they want to start family. Doctors warn after a research accomplished and found that obesity effects sperm qualities in men.

From the research, It has been found that men who is considered to be obese regarding Body Mass Index (BMI) produces less sperm and that sperm has higher level of abnormalities comparing to average weight and healthy men. This problem also can reduce chances of conceiving and increase the risk of miscarriage.

British Fertility Society point out that obesity also increases chance of infertility in women. They advised obese women must think about weight-loss pro grammes in order to improve the chance of getting pregnant.

From the patient records its found that 5,316 men attending Aberdeen Fertility Centre between 1990 and 2007 and identified 2,037 who had listed their body mass index. A BMI above 30 is classed as clinically obese.

According to tests which have been done earlier found that overweight men produced 60% less seminal fluid than men with a healthy BMI, and had 40% higher levels of abnormal sperm. Similarly, underweight men, with BMIs less than 19 are found to have poorer sperm quality comparing to healthy weight men.

“The bigger the problem we have with obesity, the bigger it will be with fertility.” said Ghiyath Shayeb, who led the study, at the European Society of Human Reproduction and Embryology meeting in Barcelona.
