How are Kefir Darm and Fruchtbarkeit related?

The direct relationship between kefir (a fermented milk drink) and fertility is not well-established scientifically. Kefir contains probiotic bacteria and yeasts that may positively influence the gut microbiome. A healthy gut microbiome is increasingly linked to improved fertility, as it can reduce inflammation and support hormone regulation. However, these connections are mainly based on animal and mechanistic studies; large-scale human trials are lacking. MyBody-X does not offer specific tests for kefir or fertility. The evidence is therefore mechanistic and preliminary. Consumers should not expect direct effects on fertility without further clinical data.
