Green tea is unfermented leaves of Camellia sinensis.

History of the 10th century BC talks about the human user of tea because of its great medicinal value.

It is supported by several research findings that tea has an effect on the regulation of blood pressure, serum lipids, diabetes mellitus, and obesity.

The anti-inflammatory, antioxidant and antiproliferative effects of tea can provide health benefits such as anti-cancer or chemopreventive effects.

Green tea is considered a healthy drink.

But the effect of green tea on fertility is uncertain.

There were conflicting views from the reported documents.

Some IVF centers do not recommend drinking green tea during pregnancy.

Green tea harms the level of folate in the blood.

Green tea can reduce the rate of folic acid absorption in the body and increase the risk of pregnancy.

In contrast, another document states that drinking green tea can improve male and female fertility.

Polyphenols and hypoxanthine are two phytochemicals present in green tea that increase the chances of getting pregnant by helping the eggs to mature properly and preparing the body for the pregnancy to continue.

  • Green tea can also help increase IVF success. L-theanine present in green tea helps maintain body hydration levels and improves sperm mucus, which facilitates sperm movement to fertilize eggs.
  • Weight management is an important step in the treatment of IVF. Green tea extract has the potential to improve fat metabolism.
  • Human studies provide evidence that drinking green tea extract can upregulate fat metabolism at rest and during exercise.
  • A clinical study performed on Asian and Caucasian populations yielded different results, as did Asian populations showing greater weight loss (1.51 kg) than Caucasians (0.82 kg).
  • A study of 12 healthy men showed that acute drinking of green tea extract could improve fetal oxidation during moderate-intensity exercise and also improve insulin sensitivity and glucose tolerance in participants.
  •  It has been observed that consuming green tea extract can improve endurance capacity. The Kao team in Japan conducted a study stating that the energy-increasing effect of green tea extract when dose-dependent and regular consumption of green tea regulated muscle beta-oxidation, a contributing factor.
  • The anti-stress effect of green tea helps reduce the level of stress that is important in the treatment of IVF. However, an overdose of green tea is not recommended during pregnancy.
