A daily cup of coffee: a potential risk for infertility?

Coffee is a must-have drink for many people in the morning. It can refresh the mind and increase work efficiency. However, in recent years, studies have shown that excessive coffee intake may have a negative impact on fertility. This article will explore the potential dangers between a cup of coffee a day and infertility.

1. Effects of caffeine on fertility

Coffee is rich in caffeine, which is a stimulant. Moderate intake can improve concentration and alertness, but excessive intake may lead to a series of problems. Studies have found that long-term and large-scale caffeine intake can interfere with women's normal ovulation and increase the risk of miscarriage and infertility.

According to the New York Times, women who drink more than two cups of caffeine beverages containing more than 200 mg of caffeine (equivalent to two shots of espresso) a day during IVF treatment have a lower chance of getting pregnant than other women. This is because caffeine can affect the development of eggs and the fertilization process, thereby reducing the chances of pregnancy.

2. Effects of caffeine on male fertility

In addition to its effects on female fertility, caffeine may also have adverse effects on men. Studies have shown that high caffeine intake can lead to decreased sperm count and quality, thereby reducing male fertility.

A study published in the American Journal of Clinical Nutrition showed that men who consumed more than 300 mg of caffeine per day (equivalent to three cups of espresso) during IVF treatment had significantly lower success rates than men who consumed less or no caffeine. This is because high doses of caffeine can damage sperm DNA and increase the risk of deformed sperm and poor motility.

3. Are there similar problems with other beverages?

In addition to coffee, caffeine is also found in drinks and foods such as tea, cola, and chocolate. However, the caffeine content in these foods and drinks is relatively low and will not have a significant effect on fertility.

A study published in the European Journal of Human Reproduction and Embryology found that women who consumed more than 200 mg of caffeine a day (equivalent to two cups of espresso) had significantly lower rates of pregnancy success than those who consumed less or no caffeine. However, similar effects were not found when caffeine was consumed in the same dose in foods and drinks such as tea, cola and chocolate.

4. How to maintain moderation?

While excessive coffee intake may have a negative impact on fertility, drinking a cup of coffee in moderation is not a big problem. The American College of Nutrition recommends that adults consume no more than 400 mg of caffeine per day (about four 8-ounce cups of black coffee).

If you are planning to get pregnant or are undergoing fertility assistance technology such as IVF treatment, it is recommended to reduce your caffeine intake. Try to choose low-caffeine or decaffeinated drinks instead of coffee, and pay attention to controlling the intake of other caffeinated foods and drinks such as chocolate, tea and cola.

in conclusion

A cup of coffee a day is safe for most people, but excessive intake may have a negative impact on fertility. Women before and after pregnancy and men when planning pregnancy should pay attention to moderate caffeine intake to protect the health of themselves and their future babies.
