Mir J, et al. - This study was performed to assess if the weight loss in obese men improved their fertility with respect to DNA fragmentation index and morphology. Findings revealed a significant positive correlation of weight loss with percentage of DFI. A significant improvement in morphology was evident after weight loss. DFI and morphology showed significant relationship with adiposity (possibly contributing to subfertility in this population) in one of the largest cohorts of male fertility and obesity.
