70% of women with undiagnosed infertility have been found to have increased levels of oxidative stress and inflammation in their body. Oxidative stress can impact egg quality and a calm and balanced immune system is vital for acceptance of the blastocyst when it’s trying to implant. Improving the diet, as well as gut health is key to reducing these markers.
Short Chained Fatty Acids (SCFAs) are compounds produced when your gut bacteria break down dietary fibre. SCFAs help regulate inflammation, strengthen gut barriers, and even influence hormone balance.
A recent study [PMID: 37432305] on SCFAs and how they might impact pregnancy outcomes during fertility treatment; showed women with higher SCFA levels had better pregnancy outcomes when undergoing IVF/ICSI-ET. This may also be due to the fact that higher SCFA levels are associated with higher intake of fruit and vegetables and whole foods in the diet.
Not only do our good bacteria produce short chained fatty acids to help keep us healthy; “bad” bacteria also known as pathogenic or opportunistic bacteria can damage the mucous membranes and increase inflammation in the body. They also produce toxic bi-products, which contribute to ill health. Therefore balancing good and bad bacteria is an important part of ensuring there are less toxins and less inflammation present that could negatively impact pregnancy and fertility.
