Does Soy Cause Infertility?

Soy has been hailed as beneficial in alleviating symptoms of menopause, as well as being a superfood against cancer. When a person is pregnant, soy is a particularly good source of protein, especially if a person has a vegetarian diet. On the contrary, if a person is trying to become pregnant, consuming an excess amount of soy could have an effect on the body. In this article we shall be separating facts from fiction so that you can be aware of the effects of soy. As well, we shall discuss how you can safely incorporate soy into your diet while you are trying to conceive.

Soy and Infertility

There are very many causes of infertility, but soy does not typically cause infertility when consumed in moderation. Soy contains a form of plant-based estrogen known as isoflavones. When a person consumes soy excessively, the isoflavones could cause infertility. Other effects of high levels of soy protein in the body are lowered levels of follicle stimulating hormone (FSH) and luteinizing hormone (LH) which are central to ovulation and fertility. As well, excessive soy consumption could increase a person’s menstrual cycle length. 

Fact Vs. Fiction

Soy is a very good and rich source of protein, with studies showing that soy and tofu are beneficial in reducing hot flashes in menopausal women. There is no substantial evidence pointing to soy intake reducing the risk of breast cancer. However, in this vein, evidence suggests that for soy to be preventative in this way, a person needs to consume it right from childhood.

Does Soy Really Cause Infertility?

Yes. Indeed soy could potentially affect a person’s fertility. The reason for this is that soy contains isoflavones which are compounds similar to estrogen. However, one has to consume at least 60 grams of soy daily, for a period of more than one month for it to impact their reproductive health. For reference, a typical serving of soy consists of eight to ten grams of soy protein, meaning one needs to consume at least six servings daily to reach the levels that could impact their fertility.

Moderation Is Key

The recommendation with soy intake, as with any other food, is to consume soy and tofu products in moderation. When one is trying to conceive, including soy in moderate quantities is beneficial because soy contains proteins, essential vitamins and fibre. However, soy consumption must be done in tandem with other nutritious foods. It is important to ensure that one consumes a variety of foods from each food group in order to have a sufficient supply of nutrients in the body. This way, it will not impact fertility or be disruptive to normal hormone production.

What You Should Remember?

Balance: 

Ensure that you consume a variety of both plant and animal-based proteins in your diet. As well ensure that you consume a variety of foods from other food groups. This ensures that you are getting the necessary nutrients for your body. If you consume a vegetarian diet, speak to a professional licensed nutritionist to advise you on how to supplement animal protein in your diet.  

Consult Your Doctor:

If you have any concerns regarding soy and tofu products where your fertility is concerned, consult a professional healthcare provider. They are best placed to advise you on your dietary needs, based on your eating habits and fertility goals. 

Conclusion

Soy and tofu products are rich in nutrients and can be added to a person’s diet, whether they are vegetarian or not. As well, the nutrients provided are beneficial when trying to conceive, or when one is already pregnant. It is important to note that consuming soy or tofu products in very large quantities could impact hormone levels and one’s fertility. As such, it is important to moderate the intake of soy products, while including other sources of nutrition in one’s diet.
