Does coffee drinking affect fertility in men?

In recent years, with the accelerated pace of life and increased work pressure, coffee has become one of the indispensable drinks in the daily life of many people. However, the question of whether men's coffee drinking will affect their fertility has attracted widespread attention. This article will explore this issue from multiple angles.

1. Effects of caffeine on sperm quality

First of all, we need to understand that coffee is rich in caffeine. Studies have shown that excessive caffeine intake may have an adverse effect on sperm quality. A study of 2,000 men found that after consuming more than 300 mg (about three cups) of caffeine per day, sperm count and motility decreased.

In addition, another study also found that sperm morphology abnormalities were higher in those cultured under high concentrations of caffeine exposure. These results suggest that excessive coffee intake may damage male sperm quality and thus affect fertility.

2. Effects of caffeine on testicular function

In addition to its effects on sperm quality, caffeine may also have adverse effects on male testicular function. An experimental study on mice found that long-term high-dose caffeine intake can lead to testicular atrophy and sperm production disorders.

In addition, another human study also found that male hormone levels decreased after consuming more than 200 mg of caffeine per day. These results suggest that excessive coffee intake may interfere with the normal functioning of the male endocrine system and thus affect fertility.

3. The relationship between caffeine and other bad lifestyle habits

In addition to its direct impact on fertility, coffee drinking is also associated with other bad lifestyle habits. For example, many people like to smoke after drinking coffee. However, smoking has been shown to damage sperm quality and quantity and increase the risk of male infertility.

In addition, many people add sugar and dairy products to their coffee. A high-sugar diet has been shown to be associated with decreased sperm quality and male infertility. The hormones in dairy products may also have an impact on male fertility.

4. Reasonable control of caffeine intake

Despite the above research results, it does not mean that men can't drink coffee at all. In fact, moderate coffee intake is good for health. According to the European Food Safety Authority (EFSA), it is safe to consume less than 400 mg of caffeine per day (about four cups).

In addition, there are other ways to help reduce the potential effects of caffeine on fertility. For example, when drinking coffee, you can choose low-concentration or most caffeine-free products; at the same time, pay attention to controlling other bad lifestyle habits such as smoking and high-sugar diet.

in conclusion

In summary, excessive coffee intake may have adverse effects on male sperm quality, testicular function, and overall fertility. However, moderate coffee intake is beneficial to health and does not have a significant impact on fertility. Therefore, men should pay attention to controlling their coffee intake and adopt other good lifestyle habits to maintain their health and fertility.
