A Healthy Microbiome May Improve Fertility in Both Women and Men

A healthy diet can support a healthy microbiome and improve fertility.

In the United States, about 12% of women of childbearing age (15-44) have difficulty getting pregnant or carrying a pregnancy to term. This is considered infertility. Factors that contribute to infertility include age, female reproductive disorders, male infertility, and lifestyle factors such as obesity and smoking. Some evidence suggests that a healthy gastrointestinal (GI) system may be linked to fertility in women.

Studies have shown that the gut microbiome, which is the collection of microorganisms in the digestive tract, has been linked to various aspects of health, including fertility in both men and women. In women, a healthy gut microbiome has been associated with a balanced hormonal system, proper immune function, and optimal vaginal health, all of which are important for fertility. In men, the gut microbiome has been linked to sperm health and testosterone production. An imbalanced gut microbiome may contribute to conditions such as inflammation and oxidative stress, which can negatively impact fertility.

However, more research is needed to fully understand the relationship between gut health and fertility and to determine the specific ways in which the gut microbiome affects fertility. Maintaining a healthy gut through a balanced diet and probiotics may have benefits for fertility, but it is also recommended that you consult with a health care practitioner to see what is best for your individual needs.

How the Gut May Impact Fertility

Gut Microbiome

The gut microbiome plays a role in overall health and has been shown to impact fertility in women. A healthy gut microbiome can help regulate hormonal imbalances, improve insulin sensitivity, and reduce inflammation, which can all have a positive impact on fertility.

Hormonal Regulation

The gut is involved in the production and regulation of hormones, including hormones involved in the menstrual cycle and fertility. A healthy gut can help regulate hormones and improve fertility.

Inflammation

Chronic inflammation can impact fertility and has been linked to conditions such as endometriosis and polycystic ovary syndrome (PCOS). A healthy gut can help reduce inflammation and improve fertility.

Insulin Sensitivity

Insulin resistance can impact fertility. A healthy gut can help regulate insulin sensitivity and improve fertility.

Supplements for a Healthy Microbiome

A healthy gut microbiome is essential for overall health. There are several supplements that may help support a healthy gut.

Probiotics

Probiotics are live bacteria and yeast that can help support a healthy gut microbiome. They can be found in fermented foods such as yogurt, kefir, and sauerkraut, as well as in supplement form.

Prebiotics

Prebiotics are non-digestible fibers that can help promote the growth of beneficial bacteria in the gut. They can be found in foods such as bananas, garlic, onions and asparagus, as well as in supplement form. Many times prebiotics in the form of fructooligosaccharides (FOS) are found in probiotic supplement blends.

Fiber

Fiber is important for promoting a healthy gut microbiome, as it provides a food source for beneficial bacteria in the gut. It can be found in foods such as fruits, vegetables and whole grains.

Vitamin D

Vitamin D is important for overall health, including gut health, and can help support a healthy gut microbiome.

Glutamine

Glutamine is an amino acid that can help support gut health and may have a positive impact on the gut microbiome. It can be found in foods such as beef, chicken and beans, as well as in supplement form.
