Lacticaseibacillus rhamnosus DSM 14870

Lacticaseibacillus rhamnosus DSM 14870 (also known as L. rhamnosus PB01) is a strain primarily studied in the context of vaginal health and male reproductive parameters. Observational studies and small animal trials have examined vaginal capsules containing DSM 14870, often combined with L. gasseri DSM 14869, in the context of colonization after bacterial vaginosis treatment. Animal research has also investigated sperm kinematic parameters and metabolic-reproductive outcomes in diet-induced obesity and diabetic models. An in vitro postbiotic study examined sperm quality markers in response to strain-derived fermentate. Human clinical evidence remains limited to observational vaginal-health studies; reproductive and metabolic research is largely preclinical. These are research topics, not findings; the papers do not establish that this strain treats or prevents any condition.
