The va**nal microbiome refers to all the microorganisms that live in the va**na. Unlike the gut microbiome, in which diversity is considered a sign of health, the va**nal microbiome is unusual in that it should be a ‘low diversity environment’, heavily dominated by lactobacillus species.
These lactobacilli produce acidic compounds like lactic acid and hydrogen peroxide, which maintain va**nal pH and help protect the va**na from colonisation by other types of bacteria.
In pregnancy, a healthy va**nal microbiome serves a critical role in the defence of the mother and baby against infection.
Unfortunately, va**nal dysbiosis (or the colonisation of the va**na with non-Lactobacilli species such as Gardnerella va**nalis, Enterococcus faecalis and Ureaplasma parvum) has been associated with many adverse fertility and pregnancy outcomes, including unexplained infertility, recurrent implantation failure, miscarriage, chorioamnionitis (infection of the membranes) and preterm birth.
It is for this reason we strongly recommend comprehensive screening of the va**nal microbiome prior to pregnancy in the context of preconception care, as well as using tailored prebiotic and/or probiotic support for a healthy va**nal microbiome throughout pregnancy, under the guidance of a qualified practitioner.
At PHF, all of our naturopaths have extensive training in the area of va**nal health and dysbiosis and this is central to much of our work in holistic fertility and pregnancy care.
