Changes in Hormonal Profile and Body Mass Index in Women with Polycystic Ovary Syndrome After Probiotic Intake: A 12-Week Placebo-Controlled and Randomized Clinical Study.

INTRODUCTION

The beneficial effect of probiotics on the improvement of carbohydrate and lipid metabolism, as well as body mass index (BMI), has been demonstrated in various patient groups. We aimed to investigate the effect of a multi-strain probiotic on the hormonal balance of women with PCOS. Ethical approval was obtained from the Bioethical Committee.

METHODS

The study was designed as a 12-week, randomized, double-blind, placebo-controlled clinical study. The probiotic SanProbi Barrier capsules, which contain a unique composition of nine probiotic bacteria strains (), were used in the study. The mean age of the study participants was a mean of 28.42 ± 5.62 years. A total of 50 women with PCOS, diagnosed based on Rotterdam ESHRE criteria, were included in the study. Among them, 25 women were randomized to a placebo group, and 25 to a probiotic group.

RESULTS

A comparison of changes in individual hormone levels between groups confirmed statistically significant differences for TSH, androstenedione, SHBG, and BMI. In the case of LH, the statistical significance of the difference in delta change in the probiotic group was demonstrated with the use of a one-tailed test.

CONCLUSIONS

Probiotic supplementation may serve as an alternative supporting treatment, especially in the phenotype of women with a high FAI index. Probiotic therapy is also effective in reducing BMI in overweight women with PCOS.
