Obesity decreases the chances that a woman will get pregnant, and the more obese she is, the worse her prospects of conception, Dutch researchers said.
Researchers at the Academic Medical Center in Amsterdam looked at how obesity affects women who are still ovulating but having trouble with conception.
The study, published in the journal Human Reproduction, included more than 3,000 couples between 2002 and 2004 in 24 hospitals in the Netherlands.
Dr Jan Willem van der Steeg and colleagues looked at the relationship between fertility in these women and their body mass index, a ratio of weight to height. Women with a BMI of 30 or higher are considered obese...
The researchers found that women with a BMI of 30 or higher had significantly lower probability of becoming pregnant naturally, compared with normal weight women who had BMIs of between 21 and 29.
"In the case of a woman with a BMI of 35, the probability of spontaneous pregnancy was 26 percent lower, and in the case of a woman with a BMI of 40, it was 43 percent lower," van der Steeg said in a statement...
"It is possible that obese women may have disturbed hormone levels, which decrease the chances of successful fertilization and implantation," he said.
