The study included 163 women: 48 of them were healthy, 72 were formally diagnosed with PCOS, and 42 had polycystic ovary morphology (PCOM). The women in the PCOM group have ovarian cysts that LOOK LIKE PCOS-type cysts, but they didn’t meet the other criteria of PCOS required for the study.

Many other studies have proven that women with PCOS have fewer types of gut microbes that those without it. Other studies have confirmed that metabolic conditions are also linked with changes in the microbiome.
