Potential role of 4-hydroxyisoleucine in enhancing fertility in male mice with diet-induced obesity.

ABSTRACT:

Background

Obesity is associated with hormonal imbalance, increased oxidative stress, and inflammation in the testis. These conditions adversely affect sperm quality, leading to impaired male fertility. Therefore, therapeutic interventions to counteract the adverse effects of obesity are crucial. This study explored the therapeutic effects of 4-hydroxyisoleucine (4-HIL) on fertility in male mice with diet-induced obesity.

Methods

C57BL6 male mice (n=45) were randomly divided into normal diet (ND, n=15) and high-fat diet (HFD, n=30) groups for 10 weeks. The HFD group was then randomized into untreated (HFD, n=15) and 4-HIL-treated (200 mg/kg/day, intraperitoneal injection, HFD + 4-HIL group, n=15) for 6 weeks. ND and HFD controls received saline (0.3 mL/30 g body weight) thro
