Does green tea cause infertility?​

Green tea is one of the most popular health drinks consumed across the globe, and it offers many potential health benefits. It has antioxidant properties, which may benefit certain people. Yet many people trying to conceive wonder whether green tea can cause infertility.

The answer is no. Current scientific studies have found no evidence that moderate green tea consumption causes infertility in men or women. It is important to understand fertility in order to avoid the stress caused by myths about infertility and nutrition.

Beverages and reproductive health

Since green tea contains caffeine, it should be consumed in moderation. Because excessive consumption of any food or beverage can negatively affect health, it is important to understand the effects of diet and lifestyle on fertility. However, there is no direct link between green tea and infertility.

Green tea contains antioxidants called catechins. Catechins are compounds that can protect cells from oxidative stress, which has been linked to reduced egg and sperm quality. According to several animal and laboratory studies, green tea may offer some reproductive benefits, but there is not enough evidence to recommend it as a treatment for infertility.

The main aspect to consider when drinking green tea is its caffeine content. Health organizations generally advise that caffeine intake should not exceed 200 mg per day when planning for and during pregnancy, regardless of the source, including tea, coffee, energy drinks, and sodas.

Some studies have found that excessive caffeine intake can lower fertility and negatively affect pregnancy, while others have found no such effect. Catechins in green tea may mildly reduce folic acid absorption if consumed in excess. Folic acid is an important supplement to take before and during pregnancy to help prevent neural tube birth defects.

This does not mean that women should avoid green tea altogether. Instead, they should:

Continue taking the recommended folic acid supplement.

Avoid excessive green tea consumption.

Drink green tea at a different time than their folic acid supplement, if concerned.

Preventable causes of fertility problems

When discussing infertility, it is important to remember that fertility mainly depends on a few factors: the quality of the egg and sperm, the condition of the fallopian tubes, and any abnormalities in the uterus or hormones. These factors are thoroughly evaluated when a couple is experiencing infertility, and in most cases the cause lies within one of them. If no cause is identified, it is known as “unexplained infertility”.

Impact of lifestyle habits on conception

Green tea does not directly affect fertility. However, overconsumption of green tea may lead to excessive caffeine intake, which could affect reproductive health. This is quite rare, because green tea contains less caffeine than coffee. To maintain good reproductive health, it is important to make healthy lifestyle choices such as quitting smoking, reducing alcohol intake, getting adequate sleep, staying well hydrated, and maintaining a normal BMI. These lifestyle changes may not reverse infertility, but they can improve some conditions that contribute to it. For example, a high BMI may cause hormonal imbalances, and weight loss can help regulate hormone levels and therefore increase the chances of conception.

A proper evaluation by a fertility expert is required to identify the exact cause of infertility. Treatment is planned according to the diagnosis and may include lifestyle modifications, medications, or a combination of both. It is also important to understand that infertility can be caused by both male and female factors.
