Obesity-related poor sperm quality is a significant public health issue, acting as a major contributor to male infertility. Dietary intervention has emerged as an effective strategy to manage obesity and improve sperm quality. Soluble dietary fiber (SDF), an essential nutritional component, plays a crucial role in regulating host health. Notably, insufficient SDF intake has been associated with both obesity and low sperm motility. However, the effect of SDF supplementation on sperm quality in males with obesity remains unclear. Thus, we conducted a randomized, placebo-controlled study to investigate the effect of SDF supplementation on sperm quality in males with obesity.
