Miscarriage & the Uterine Microbiome

1st Trimester & Beyond

Can your microbiome impact your chance of having a miscarriage?

Well, according to this article published in July 2023, yes, it can.

The role of the uterine microbiome (a community of microorganisms) in successful embryo implantation and a healthy pregnancy is gaining clarity. Various studies highlight that the dominance of Lactobacillus species in the uterine microbiome increases the likelihood of pregnancy and reduces the risk of miscarriage.

(I love that science is really starting to bring forward the connection between our 

microbiome and fertility!)

This randomized study took it up a notch – women with three previous unsuccessful embryo transfers were randomly assigned to a daily routine of Lactobacillus vaginal suppositories for six days, beginning concurrently with the initiation of progesterone in preparation for transfer.

The results?

The key takeaway here is that the miscarriage rate notably dropped among women using probiotic suppositories.

While this research field is in its early stages, if you’re dealing with unexplained infertility, recurrent miscarriage, or a series of unsuccessful embryo transfers, consider integrating probiotics (suppositories and orally) into your supplement regime*. This can apply to both treatment and non-treatment cycles.

Adding to this…

You may also want to take a look at your diet. This can impact the health of our gut microbiome and ultimately also that of the rest of the body.  Prebiotic foods like artichoke, garlic, leeks, and onions are wonderful additions to support the proliferation of those fertility-friendly bacteria species in our gut which only help to support the overall health of our immune system, ability to absorb nutrients, and our gut plays a role in hormone regulation. All important for the health of our fertility!

Are you surprised to learn that bacteria in your body can impact your fertility?
