So I'm quite interested in this topic. I've always been into probiotic foods, I had my own water kefir at home for years, made my own fermented vegan cheese, was constantly making fermented recipes from a book on the subject, I even went on a course called Go Fermental.
After 2 unsuccessful IVF transfers I had a lot of tests, one of them looked at the microflora in my uterus, I had 0.00% lactobacillus (good bacteria), I was under a specialist who knows about lining issues and they couldn't believe the result given my health diet. It probably happened because I had a coil which must have taken up dysbiotic bacteria and once they set up home the only thing that would shift them was a course of antibiotics. IVF procedures and surgery is also felt to put people at a higher risk of dysbiotic microflora. After 7 days of antibiotics I then took 10 days of vaginal probiotics, I've attached the list the lab recommended.
I also take an oral one called femdophilus, there are studies showing that this improves the microflora in the genital tract. There are lots of different forms of probiotics and it's important to take one which is going to have an impact in the uterus.
I am now having a FET, so far they say the lining looks good in quality but I won't know for sure until transfer day. As soon as I started the treatment I stopped feeling sore, I actually hadn't realized I'd even been sore, but it's likely I've had undiagnosed bacterial vaginosis for some time.
I'm hoping the microflora issues will explain why I've never been successful to date. There is evidence about how important the microflora is. This study https://doi.org/10.1016/j.ajog.2016.09.075 separated women with more than 90% lactobacillus vs those with less than 90% lactobacillus, the outcomes were statistically significant:
Implantation 60.7% vs 23.1%
Pregnancy 70.6% vs 33.3%
Ongoing pregnancy 58.8% vs 13.3%
Live birth 58.8% vs 6.7%
So from my experience:
- I would recommend that if anyone is considering an ERA then get the EMMA and ALICE to look at the bacteria at the same time.
- If you're worried about your microflora but you aren't in a position to have the endometrial biopsy, then you might want to consider a vaginal swab. There are companies that will tell you the microflora in the vagina for about £200, it hopefully will give some indication of what the microflora in the uterus might look like. This can be important because if dysbiotic bacteria are found then probiotics alone may not shift it, as in my case, the swab would hopefully help identify the most appropriate antibiotic.
- By all means take probiotics that will help your gut but if you're looking for one that improves the genital tract flora then I'd go for something like femodophilus. Another one that I’ve heard of is this one which is a prenatal vitamin that has probiotics in it https://www.nuafertility.com/nuabiome-women/
