摘要:

镉是生殖毒性最强的重金属之一,生物半衰期长达20 ~ 40年,进入人体后常在睾丸蓄积,并可引发睾丸、附睾功能损伤,导致精子数量、运动参数及正常形态的降低,甚至引发雄性子代生殖系统的功能异常。重金属镉诱导雄性生殖功能损伤的机理尚未完全阐明,也缺乏有效治疗手段。因此,这一问题受到学者们的长期关注。大量研究提示镉可能通过干扰激素分泌、诱导氧化应激、激活炎症反应和凋亡以及引发能量代谢紊乱等途径对雄性生育能力造成损害。本文对既往发表的研究进行系统的回顾和综述,对其损伤机制进行总结,旨在为寻找镉诱导雄性生殖功能损伤的治疗靶点寻找提供新的思路。

Abstract:

Cadmium is one of the heavy metals with severe reproductive toxicity, whose half-life lasts 20 to 40 years. Cadmium could induce dysfunction of testis and epididymis for its significant accumulation in human testis, and the amount, motility parameters and morphology of sperm change abnormally. The adverse change could also extend to male offspring and cause the impairment of their reproductive system. There has been no clear mechanism of how cadmium induces dysfunction of male reproductive system, and treatment for the adverse influence on male reproductive system by cadmium has not yet been found. Therefore, this problem has been discussed in reproductive and environmental field for a long time. A number of previous investigations showed that cadmium could damage male fertility by followed pathways, including interfering with hormone secretion, inducing oxidative stress, activating inflammation and apoptosis, and causing energy metabolism disorder, etc. In order to enlighten new ideas for therapeutic targets of male reproductive function damage induced by cadmium, we systematically reviewed and summarized the findings of previous publications in this paper.
