Abstract
The global decline in sperm quality in men is closely associated with environmental exposure to the plasticizer Di-(2-ethylhexyl) phthalate (DEHP), but the molecular mechanisms underlying its induction of asthenozoospermia (AZS) remain incompletely understood. By integrating the toxicological targets of DEHP and differential genes in AZS patients, and combining machine learning, molecular docking, and dynamics simulations, this study successfully identified hub genes and signaling pathways induced by DEHP in AZS, aiming to provide new strategies for the prevention and treatment of this disease. A total of 26 toxicological targets were identified, with FGFR1, MMP7, and ST14 clearly defined as playing crucial regulatory roles in DEHP-induced AZS. This study also reveals that DEHP may induce reproductive system inflammation, affecting the proliferation and survival of reproductive cells, and subsequently impacting sperm vitality, possibly through regulating the mTORC1 pathway, TNF-α signaling via the NF-κB pathway, and MYC targets v1 pathway. Furthermore, changes in the immune microenvironment revealed the significant impact of immune status on testicular function. In conclusion, this study provides important scientific evidence for understanding the molecular mechanisms of AZS and developing prevention and treatment strategies based on toxicological targets.
