高碘摄入对男性(雄性)生精能力的影响

Influence of intake excess iodine on male spermatogensis

碘元素是机体所必需的微量元素,参与和调节甲状腺激素的代谢,对机体正常生理活动和生殖功能产生重要作用。男性生精能力不仅受自身基因、内分泌等因素调控,也受到环境因素影响。在实际中,人体受环境因素的影响大于自身因素。因此,认识并确定环境因子对男性生精能力的作用一直是男性生殖领域的热点。认识碘元素,特别是高碘剂量摄入对于男性生精能力的关系,对保证正常精液参数具有指导意义。本文着重阐述碘元素影响男性生精能力的机制,以及碘干扰甲状腺激素从而影响睾丸组织的关系,期望对碘元素在男性生精过程中的作用有新的认识。
