The Effect of 8 Weeks of Swimming Training Combined with Soy Extract on the Expression of FN1-ARC-NGFR-BDNF Levels Related to Neurogenesis in Mice with Polycystic Ovary Syndrome Fed a High-Fat Diet and Letrozole

Abstract

Background: Polycystic ovary syndrome (PCOS) is the most common endocrine disorder among women and has lifelong health effects. This study aimed to investigate the physiological effects of PCOS on neurogenesis and cognitive symptom improvement through lifestyle changes and the use of complementary and alternative medicine.

Methods: In this experimental study, 30 female C57BL/6 mice with a mean weight of 18±2 kg and an age of 6 to 7 weeks were randomly divided into five groups: control group, polycystic group, polycystic + swimming exercise group, polycystic + soy group, and polycystic + exercise + soy group. Real-time PCR measured gene expression. Genes were selected with the help of bioinformatics software. ELISA evaluated luteinizing hormone(LH ) concentration.

Results: FN1-ARC-NGFR-BDNF genes showed decreased expression in mice with PCOS compared to the control group. On the other hand, the expression of FN1-ARC-NGFR-BDNF genes in mice with PCOS, swimming training, and soy supplement consumption significantly increased compared to the PCOS group. Simultaneous administration of swimming training and soy supplement consumption significantly increased LH concentration (p<0.001) and expression of FN1-ARC-NGFR-BDNF genes (p<0.05).

Conclusion: This study showed that combining swimming training and soy extract consumption can enhance neurogenesis in a PCOS model and improve cognitive symptoms. Our findings confirm that this combination not only enhances the function of the nervous system but also contributes to overall health improvement through hormonal regulation. These results provide a new avenue for complementary therapies in the management of PCOS.
