The gut flora affects hormone balance, immune system, inflammation and nutrient absorption – all factors that play a major role in fertility, egg and sperm quality and the chances of pregnancy. In addition, it has been seen that the composition of the vaginal flora can affect how easily an embryo attaches after IVF.
Probiotics are not a magic shortcut, but can be an important support for creating a more fertility-friendly internal environment.
Why is gut flora important when trying to get pregnant?
A balanced intestinal flora contributes to:
-
hormone metabolism works smoothly (for example, estrogen metabolism)
-
low-grade inflammation is kept down
-
the immune system acts in a balanced way
-
nutrients from food and supplements are absorbed more efficiently.
All of this is fundamental when the body is able to produce healthy eggs, good sperm and create a stable environment for an embryo.
What do we know about vaginal flora and fertility?
Studies have shown that:
-
a Lactobacillus-dominated vaginal flora is linked to better IVF outcomes
-
Disturbed flora, such as in bacterial vaginosis, can increase the risk of non-implantation and early miscarriage
-
Treatment and sometimes probiotic strains can help restore balance in some women.
This makes the vaginal microbiome an important, but often forgotten, part of the fertility picture.
How can probiotics be used in fertility treatment?
Probiotics can have several purposes:
-
support gut health, which benefits hormone balance and nutrient absorption
-
help restore balance after antibiotic courses
-
in some cases, positively affect the vaginal flora (depending on the strain and method of administration).
The effect depends a lot on which strains are used and how long they are taken. As with other fertility supplements, it is reasonable to think in terms of months, not weeks – preferably 6–12 months if possible, with at least 3 months of use before IVF or conception attempts.
How does Fay Hepper position herself on probiotics?
Fay Hepper has chosen to include probiotics in her fertility concept with a focus on:
-
intestinal health and nutrient absorption
-
the connection between microbiome, hormones and inflammation
-
long-term support in the months before pregnancy or IVF.
The probiotic is often used together with prenatal vitamins, omega-3s, and ubiquinol as part of a holistic approach.

FAQ: Probiotics and Fertility
Can probiotics improve my chances of getting pregnant?
Probiotics can contribute to better intestinal and sometimes vaginal flora, which in turn can create more favorable conditions for hormonal balance, inflammation and implantation. It is not a guarantee, but an important building block in a holistic approach.
How long should you take probiotics?
The intestinal flora changes slowly. Therefore, it is reasonable to take probiotics continuously for several months. When trying for fertility, 6–12 months is a good benchmark, with at least 3 months before IVF or fertilization attempts.
Can probiotics cause side effects?
Some people experience temporary gas or stomach changes at first. This usually stabilizes after a week or so. In case of serious illnesses or a weakened immune system, you should always consult a doctor.
