The Claim

In a mouse model of DHT-induced polycystic ovary syndrome (PCOS), daily oral administration of 1 × 10⁹ CFU of Bifidobacterium longum subsp. longum BL21 for 8 weeks was associated with increased alpha diversity of the gut microbiota and enrichment of beneficial bacterial genera, including Bifidobacterium, Lactobacillus, and Butyricicoccus, suggesting a potential role in restoring gut microbial balance disrupted by PCOS.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

In mice with a condition like PCOS, taking a specific probiotic every day for 8 weeks seemed to improve the balance of good bacteria in their gut.
