Coffee is a favorite of many people, but a new study unveiled by Danish scholars at the 28th European Society for Human Reproduction and Embryology (ESHRE) has alarmed some coffee lovers by finding that women who drink more than five cups of coffee a day reduce their chances of getting pregnant by 50 per cent.

Dr. Ulrike Sinkler Keith Model, an expert in the fertility clinic at Aarhus University Hospital in Denmark, and his colleagues followed 3959 patients who were fertilized in vitro. The researchers collected the coffee consumption information of the patients and analyzed the factors such as age, smoking, drinking and weight. It was found that women who drank at least five cups of coffee a day had a 50 per cent lower chance of becoming pregnant, but there was no such "side effect" among women who drank less than five cups of coffee a day.

Early studies on the relationship between coffee and fertility have come to different conclusions. Some studies have found that excessive caffeine intake can lead to miscarriage, while others have come to the opposite conclusion. Studies in recent years have generally believed that women who drink too much tea or coffee every day and their husbands drink too much alcohol will greatly reduce their chances of becoming pregnant.

To this end, British expert Euan Paul warned that pregnant women and women preparing to become pregnant should limit their daily caffeine intake to 200 milligrams (less than 2 cups).
