How Coffee Affects Sperm Quality and Male Fertility

February 01, 20252 min read

When it comes to fertility, most discussions tend to focus on women’s health, but men’s fertility is just as important—especially when it comes to sperm quality. If you and your partner are trying to conceive, it's essential to understand how lifestyle factors, like coffee consumption, can affect male fertility. Can your daily cup of joe impact sperm count, motility, or overall reproductive health? Let's dive into the research and find out.

The Caffeine Impact on Sperm Health

1. Semen Quality Several studies, including a 2017 systematic review published in Nutritional Journal, have found inconsistent evidence on how coffee affects sperm quality. However, cola drinks and caffeine in soft drinks have shown a negative effect on sperm count and volume. Interestingly, coffee and tea seem to have little effect on sperm quality in most studies.

2. Sperm DNA Integrity Caffeine intake, especially from coffee, has been linked to increased sperm DNA damage, such as aneuploidy (abnormal chromosome numbers) and DNA breaks. This can reduce fertility because sperm DNA fragmentation impacts its ability to fertilize an egg and can lead to pregnancy loss. Studies suggest that excessive caffeine may be a key factor contributing to these DNA issues.

3. Time to Pregnancy Another aspect that’s been observed is the association between coffee consumption and prolonged time to pregnancy. Some studies have found that male coffee drinkers may take longer to conceive, though the evidence is not conclusive. More research is needed to establish a clear link between coffee consumption and fertility timelines.

How Much Coffee Is Too Much?

While there’s no universal answer, limiting caffeine intake to less than 300 mg per day (around three cups of coffee) is often recommended for those trying to conceive. Reducing caffeine intake can reduce the risks associated with sperm DNA damage and improve overall sperm health.

The Bottom Line

Coffee, in moderation, may not have a significant impact on male fertility, but excessive caffeine—especially from coffee and energy drinks—can affect sperm quality, DNA integrity, and time to pregnancy. If you're trying to conceive, it’s a good idea to limit your caffeine intake and consider cutting back on coffee, especially if you’re drinking multiple cups per day.
