Male reproductive function and health are largely dependent on the testes, which are strictly regulated by their major cell components, i. e., Sertoli, Leydig, and germ cells. Sertoli cells perform a crucial phagocytic function in addition to supporting the development of germ cells. Leydig cells produce hormones essential for male reproductive function, and germ cell quality is a key parameter for male fertility assessment. However, these cells have been identified as primary targets of endocrine disruptors, including bisphenols. Bisphenols are a category of man-made organic chemicals used to manufacture plastics, epoxy resins, and personal care products such as lipsticks, face makeup, and nail lacquers. Despite long-term uncertainty regarding their safety, bisphenols are still being used worldwide, especially bisphenol A. While considerable attention has been paid to the effects of bisphenols on health, current bisphenol-related reproductive health cases indicate that greater attention should be given to these chemicals. Bisphenols, especially bisphenol A, F, and S, have been reported to elicit various effects on testicular cells, including apoptosis, DNA damage, disruption of intercommunication among cells, mitochondrial damage, disruption of tight junctions, and arrest of proliferation, which threaten male reproductive health. In addition, bisphenols are xenoestrogens, which alter organs and cells functions via agonistic or antagonistic interplay with hormone receptors. In this review, we provide , and evidence that currently available brands of bisphenols impair male reproductive health through their action on testicular cells.
男性生殖功能和健康在很大程度上依赖于睾丸,而睾丸又受到其主要细胞成分(即支持细胞、间质细胞和生殖细胞)的严格调控。支持细胞除了支持生殖细胞的发育外,还具有重要的吞噬功能。间质细胞产生对男性生殖功能至关重要的激素,而生殖细胞的质量是评估男性生育能力的关键参数。然而,这些细胞已被确定为内分泌干扰物(包括双酚类物质)的主要靶标。双酚类物质是一类用于制造塑料、环氧树脂和个人护理产品(如口红、面部化妆品和指甲油)的人造有机化学品。尽管长期以来对其安全性存在不确定性,但双酚类物质仍在全球范围内使用,尤其是双酚 A。尽管人们对双酚类物质对健康的影响给予了相当大的关注,但目前与双酚类物质相关的生殖健康病例表明,应该更加关注这些化学物质。双酚类物质,特别是双酚 A、F 和 S,已被报道对睾丸细胞产生各种影响,包括细胞凋亡、DNA 损伤、细胞间通讯中断、线粒体损伤、紧密连接破坏和增殖停滞,这些都威胁着男性的生殖健康。此外,双酚类物质是外源性雌激素,通过与激素受体的激动或拮抗相互作用改变器官和细胞的功能。在这篇综述中,我们提供了证据,证明目前市售的双酚类物质通过作用于睾丸细胞来损害男性生殖健康。
