Vaginal microbiome of women with premature ovarian insufficiency: a descriptive cross-sectional study.

OBJECTIVE

This study aimed to describe the vaginal microbiome of women with premature ovarian insufficiency (POI) receiving systemic hormone therapy (HT).

METHODS

Forty women with POI receiving systemic HT for at least 6 months, who were sexually active, were included in the descriptive cross-sectional study. Vaginal secretion was collected for DNA extraction followed by pyrosequencing of the 16S rRNA. The samples were pooled into phylogenetic groups (Ravel groups I-V).

RESULTS

Women had mean age of 37.13 (± 7.27) years and POI diagnosis at age 27.90 (± 8.68) years, and a mean HT duration of 8.20 (± 8.73) years. It was observed that 33.4% of the women presented group I flora, with a predominance of ; 9% group II flora, with a predominance of ; 33.4% group III flora, with a predominance of ; 15.2% group IV flora, with a predominance of anaerobic bacteria; and 9% group V flora, with a predominance of .

CONCLUSION

Women with POI receiving HT presented a vaginal microbiome with a predominance of lactobacilli in the composition of the vaginal flora, specifically and when evaluated by molecular biology through pyrosequencing of 16S rRNA.
