The Claim

In a mouse model of dihydrotestosterone (DHT)-induced polycystic ovary syndrome (PCOS), daily oral administration of the probiotic strain BL21 at a dose of 1 × 10⁹ colony-forming units (CFU) for 8 weeks was associated with improved glucose tolerance, as evidenced by a reduced area under the curve (AUC) for glucose during an oral glucose tolerance test, suggesting a potential ameliorative effect on insulin resistance in this PCOS model.

In plain English

Giving a specific probiotic to mice with a condition similar to PCOS helped their bodies handle sugar better after 8 weeks, which might mean it could help with insulin problems in PCOS.

See the scientific wording

In a mouse model of DHT-induced PCOS, 8 weeks of daily oral BL21 supplementation at 1 × 10⁹ CFU was associated with improved glucose tolerance, as indicated by a reduced glucose AUC during an oral glucose tolerance test, suggesting a potential benefit in ameliorating insulin resistance associated with PCOS.
