Several studies have investigated the impact of coffee consumption on sperm quality, with mixed results. Some research suggests that excessive caffeine intake may be associated with a decrease in sperm quality, while other studies indicate that moderate coffee consumption might actually have potentially positive effects on sperm.

Excessive caffeine consumption, including from coffee, has been linked to various reproductive issues in both men and women. It has been suggested that high caffeine intake may reduce semen volume, sperm concentration, and motility, all of which are important factors for fertility. Additionally, caffeine has been shown to increase oxidative stress in the body, which can negatively impact sperm DNA integrity and lead to sperm damage.
On the other hand, moderate coffee consumption has been associated with potential benefits for sperm quality. A study published in the journal Andrology in 2019 found that men who consumed two to three cups of coffee per day had higher sperm motility and concentration compared to those who did not consume coffee or drank it in lower amounts. Another study published in the journal Nutrition in 2018 also reported a positive association between moderate coffee consumption and sperm motility.
It is important to note that coffee is not the sole source of caffeine in a person’s diet. Caffeine can also be found in tea, soda, energy drinks, and chocolate, among other products. Therefore, total caffeine intake from all sources should be taken into consideration when evaluating its potential effects on sperm.
Overall, the relationship between coffee consumption and sperm quality is complex and not fully understood. While excessive caffeine intake may have negative effects on sperm, moderate coffee consumption might not necessarily be detrimental and could even have potential benefits. If you and your partner are trying to conceive, it may be worth considering reducing caffeine intake or discussing it with a healthcare professional to ensure the best chances of conception.
