Investigating the Link Between Intimate Health, Hygiene and Sexual Practices and the Vaginal Microbiome-The INTIMATE...

Area of Science:

• Microbiology
• Gynecology
• Women's Health

Background:

• The vaginal microbiome plays a crucial role in reproductive health.
• Understanding factors influencing its composition is vital for maintaining vaginal homeostasis.
• Intimate hygiene practices and products are widely used but their impact on the vaginal microbiome is not fully understood.

Purpose of the Study:

• To investigate the effects of intimate hygiene practices and products on the vaginal microbiome.
• To correlate specific hygiene behaviors with the composition of vaginal bacterial communities.

Main Methods:

• 16S rRNA gene sequencing was used to characterize the vaginal bacterial communities of 96 women.
• Participants completed a questionnaire on demographics, intimate health, hygiene, and sexual practices.
• Microbial composition was compared with self-reported practices and demographics.

Main Results:

• Beta diversity varied significantly with sexual practices and menopause status.
• Monogamous women and postmenopausal women showed altered Lactobacillus crispatus and Lactobacillus iners abundance.
• Regular perineal washing correlated with fewer infections, while internal washing was linked to recurrent thrush.

Conclusions:

• Sexual practices and menopause are key determinants of Lactobacillus colonization patterns.
• Most intimate hygiene practices had a minimal impact on Lactobacillus dominance in this cohort.
• Behaviors associated with significant microbiome disruption were infrequent.
