The study is mainly about the link between body weight and infertility in women who ovulate normally.

According to the studies, obesity can cause infertility problems in ovulating women. In the view of past studies, obesity is a known risk factor for ovulating problems, but the new studies have shown that obesity can even cause infertility in women who ovulate normally.

Severe obese people are 43 percent less likely to get pregnancy than normal weight women. Obesity is another risk factor for infertility in women who have regular menstrual cycles.

The study said that the disruptions in the hormone leptin regulate the appetite and energy expenditure. This condition can prevent the successful fertilization in women.
