Excessive coffee may affect conception

Coffee is a favorite of many people, but at the 28th European Society for Human Reproduction and Embryology (ESHRE), a new study published by Danish scholars has sounded the alarm for some coffee lovers – the study found that women drink coffee every day. More than 5 cups, the chance of conception will be reduced by 50%.

Dr. Ulrich Sinkske Kesmore, an expert in fertility clinics at the University of Aarhus Hospital in Denmark, and his colleagues tracked 3,959 in vitro fertilization patients. The researchers collected information on the amount of coffee consumed by the participants and analyzed them based on factors such as age, smoking status, drinking status, and weight. The results showed that female participants who drank at least 5 cups of coffee a day had a 50% reduction in the chance of conception, but this “side effect” did not occur in women who drank less than 5 cups of coffee a day.

Early studies on the relevance of coffee to fertility have different conclusions. Some studies have found that excessive intake of caffeine can lead to miscarriage, while others have reached the opposite conclusion. In recent years, studies have generally suggested that women who drink tea or coffee excessively every day and their husbands drink too much can cause a significant decrease in the probability of pregnancy.

To this end, British expert Youan Paul reminded that pregnant women and women who are pregnant should have a caffeine intake of 200 mg per day (within 2 cups).
