The Vaginal Microbiome as a tool to predict IVF success


Millions of bacteria live in the vagina, and when in balance they do a fab job!

But when these bugs get out of balance we see, problems with fertility, pregnancy loss and lower IVF success rates.


Unlike the gut microbiome which favours lots of different types of bacteria the vaginal microbiome is dominated by a type of bacteria called Lactobacillus.


Lactobacilli produce lactic acid, which is what protects the vagina against pathogens. When pathogens or anaerobic bacteria enter the vagina, the lactic acid stops them from growing and prevents them from causing an infection. The lactic acid helps maintain a low acid environment, usually below pH 4.5.


The most common overgrowths in the vagina may be called bacterial vaginosis (BV), candida overgrowth (thrush) or ureaplasma.


WHAT DOES THIS HAVE TO DO WITH IVF?


The presence of these problematic bacteria and a lack of beneficial Lactobacillus are both linked to lower success rates in women undergoing IVF . If we break this down it is lower implantation rates, higher ectopic pregnancies and higher rates of early pregnancy loss.


The vaginal microbiome is not isolated to the vagina. The bacteria can be transient and impact the entire reproductive tract. This bacteria can be picked up in the vagina and contaminate the uterus during egg extraction and embryo transfer.


WHAT CAN BE DONE?


A vaginal microbiome test is an easy way to establish vaginal microbiome health. An at home test consisting of a simple swab or tampon style test kit, that is sent off to the lab for testing. If an overgrowth in the vaginal microbiome is detected the good news is that it can be corrected through the use of supplementation, diet and lifestyle changes and sometimes with the use of antibiotics.


It is important to note that vaginal microbiome infections/imbalances can occur without symptoms for many years. But some symptoms to look out for include unusual coloured discharge, a pungent smell, itchy, lesions on the labia and surrounding skin, painful intercourse, hot, swollen membranes inside or outside the vagina.


This is not a great scenario for anyone trying to get pregnant and can make fertility challenges even greater! Also consider that in some cases a bacterial overgrowth/infection will mean that both partners need treated.


Could a bacterial overgrowth, infection or low levels of vaginal lactobacillus be holding you back from growing your family?
