The relationship between coffee and fertility is complex and may vary depending on the individual. Some studies indicate that consuming high amounts of caffeine (more than 500-600 mg per day, equivalent to more than 5-6 cups of coffee) could potentially impact fertility by disrupting hormone levels. However, moderate consumption doesn't appear to have a definitive negative impact. It's advised to generally limit caffeine intake to 200 mg per day (about 2 cups of coffee) if you are trying to conceive.
