Coffee is one of the most popular drinks among Indonesians. Known for its ability to boost alertness and energy, coffee is enjoyed by both men and women as a pick-me-up during busy days. While it can improve focus and productivity, experts caution against drinking too much coffee, especially for those concerned about fertility. So, what does the research say?

Research on the Impact of Caffeine on Fertility

The connection between caffeine intake and fertility is still a topic of discussion among health experts. Some studies have found a possible link, but the exact mechanism by which caffeine may influence fertility is still unclear.

According to Very Well Family, the concern that coffee could interfere with fertility comes from a 1988 study, which reported that women who drank one cup of coffee per day had a greater chance of experiencing difficulties when trying to conceive. Although this study is frequently referenced, newer research has not consistently replicated the same findings.

For example, a study conducted in Denmark examined women who consumed more than 300 mg of caffeine per day, roughly more than one cup of coffee, and compared them with those who consumed less than 100 mg or none at all. The results showed no significant difference in fertility between the two groups.

However, other studies have reported different outcomes. A 2017 study looked at caffeine intake and its effect on early pregnancy. The results revealed that women who drank over 300 mg of caffeine per day had a higher chance of miscarriage. This risk increased when caffeine consumption rose to 600 mg or more.

Other Factors That Influence Fertility

While some evidence suggests a potential link between caffeine and fertility, experts agree that more studies are needed. One of the biggest challenges in this research is the variation in how much and what type of coffee people drink. Another difficulty is determining whether caffeine is truly responsible for fertility problems or if other lifestyle factors play a more significant role.

Experts say fertility is a complex issue that can be influenced by many things, not just caffeine. According to the Mayo Clinic, a woman’s fertility may also be affected by age, ovulation disorders, blocked fallopian tubes, endometriosis, or other underlying medical conditions.

In addition to these health-related factors, certain lifestyle habits may also lower fertility, including:

• Smoking habits 

Smoking can damage fertility by reducing the number of healthy eggs and speeding up the aging of reproductive cells. It may also cause changes in DNA within the ovarian follicles.

• Alcohol intake

Drinking alcohol can interfere with both male and female fertility. It increases the risk of miscarriage and can affect fetal development. For couples trying to conceive, alcohol use may also reduce the chances of a successful pregnancy.

• Intense exercise

While regular physical activity is beneficial, exercising too much, especially more than five hours per week, can reduce progesterone levels and interfere with ovulation. Couples trying to get pregnant should maintain moderate levels of exercise.

• Frequent exposure to environmental pollution

Exposure to pollutants such as vehicle emissions, dust, and other harmful particles can negatively affect reproductive health in both men and women.

Fertility depends on many different factors, from physical health to daily habits. If you’re planning to conceive, it’s best to talk to a healthcare professional. A doctor can help guide you through a personalized pregnancy plan and recommend healthy lifestyle changes to improve your chances of success.
