Do you want to have a child, but it just isn't working? The solution could be closer than you think – in your vaginal flora. New scientific findings show how crucial a healthy microbiome is for your fertility.
Why your vaginal flora is more than just "down there"
Your vaginal flora is a complex ecosystem of billions of bacteria, which not only protect against infections, but also significantly influence your fertility. What many women do not know: An imbalance can be the reason why pregnancy is not happening.

The dangerous ascent: When infections move upwards
Vaginal infections = fertility problem?
Recurrent and untreated vaginal infections are more than just a nuisance – they can seriously jeopardize your fertility. Here is the mechanism:
The vicious cycle begins:
- Bacteria ascend from the vagina
- They reach the endometrium (uterine lining)
- Finally, they can reach the fallopian tubes
Hidden danger: Asymptomatic infections
Particularly insidious: Infections in the endometrium are usually completely asymptomatic. You don't notice anything, but they can already:
- Cause pregnancy problems
- Increase the risk of miscarriage
- Hinder the implantation of the fertilized egg
Fallopian tubes in danger
If bacteria reach your fallopian tubes, they threaten:
- Fallopian tube blockages
- Permanent infertility
- Increased risk of ectopic pregnancies

Microbiome revolution: What scientists have discovered
Pregnant vs. non-pregnant women
Current research shows: The microbiome of pregnant and non-pregnant women differs significantly. This finding provides important clues that your bacterial colonization has a direct influence on:
- Your fertility
- The course of a pregnancy
- The birth itself
The power of lactobacilli: Your invisible helpers
Why lactobacilli are so important
A lactobacillus-dominated flora in the uterus is the key to successful pregnancies. These "good" bacteria:
- Create an acidic environment
- Displace harmful bacteria
- Optimally prepare the uterine lining
Dangerous colonization
It becomes problematic when harmful bacteria such as Ureaplasma parvum gain the upper hand. They can:
- Hinder the implantation of the fertilized egg
- Trigger inflammation in the uterine lining
- Drastically reduce your chances of pregnancy
Impressive figures from fertility treatment
Artificial insemination: The lactobacillus effect
Studies on artificial insemination provide clear evidence for the importance of the vaginal flora [1]:
With a lactobacillus-dominated flora:
- Success rate: 60.7%
- Successful pregnancy: 70.6%
- Live births: 58.8%
With a lactobacillus-reduced flora:
- Success rate: only 23.1%
- Successful pregnancy: only 33.3%
- Live births: only 6.7%
These figures speak for themselves: A healthy microbiome can more than double your chances of having a baby!

The gut-vaginal axis: Why oral probiotics are the best way
The natural colonization route
Surprising many: The optimal way to improve your vaginal flora is through the mouth [2]! Taking probiotics orally is ideal for the following reasons:
- Natural colonization route via the gut-vaginal axis
- Depot formation in the gut as a permanent reservoir
- Sustainable colonization of the vaginal flora
Evidence from an unexpected source
A fascinating study with trans women confirms this theory [2]:
- Trans women with a neovagina often suffer from vaginal problems
- Reason: Reduced number of lactobacilli
- Solution: Oral probiotic administration
- Result: In almost half, positive colonization occurred within the shortest time
This study impressively proves that oral intake is indeed the best way to improve the vaginal flora.

Your action plan for a healthy vaginal flora
1. Preventive lactobacillus course
Recommendation: A preventive course with lactobacilli, especially if:
- You want to have a child
- You have already had problems with recurrent infections
- You are preparing for a fertility treatment
2. The right product choice
Look for:
- High-dose lactobacilli (at least 10 billion CFU)
- Specific vaginal flora strains (L. crispatus, L. gasseri, L. jensenii)
- Stomach acid-resistant capsules
- Scientifically proven strains
3. Holistic approach
In addition to taking probiotics:
- Avoid excessive intimate hygiene
- Wear breathable underwear
- Reduce stress (influences the microbiome)
- Eat a microbiome-friendly diet
When should you see a doctor?
Make an appointment if:
- You have been trying to get pregnant for over a year
- You have recurrent vaginal infections
- You have already experienced miscarriages
- You are preparing for a fertility treatment
Conclusion: Your microbiome as the key to motherhood
Science makes it clear: Your vaginal flora is a crucial factor for your fertility. The good news? You can actively do something about it!
With the right probiotic strategy – best taken orally – you can:
- Significantly improve your chances of pregnancy
- Reduce the risk of miscarriage
- Stabilize your microbiome in the long term
