Shanna Swan: 研究表明男性睾酮水平可能正在下降,但尚需进一步研究确认。精子数量的数据比睾酮水平的数据更可靠,因为精子数量的研究历史更长,数据来源也更多。睾酮对男性发育至关重要,尤其是在胎儿发育早期以及青春期等多个阶段,对性功能也至关重要。全球生育率下降,尤其是在东亚地区,这可能与内分泌干扰物有关。精子数量低下的男性和生育能力受损的男女寿命更短。使用睾酮补充剂的男性不会增加精子数量。过去65年来,全球精子数量持续下降,下降速度还在加快。可以通过改善饮食、戒烟、控制体重、进行锻炼和减压来改善精子数量。女性在社会中的地位也影响生育率。内分泌干扰物会影响内分泌系统,从而影响生育能力。人们主要通过饮食、皮肤接触和呼吸三种途径接触内分泌干扰物。食物中的内分泌干扰物可能来自种植过程、包装过程以及储存过程。建议尽量购买简单包装的农产品,减少使用塑料制品。回收塑料并不能完全解决问题,建议尽量减少使用塑料制品。微塑料和纳米塑料会对人体健康造成危害。高质量的净水器可以有效去除水中的部分污染物,但蒸馏水更安全。内分泌干扰物会影响大脑发育,从而影响儿童的行为和语言发展。现代社会中,女性和男性推迟生育的现象越来越普遍,这与生育率下降有关。以色列的生育率没有下降,这与辅助生殖技术的普及有关。未来人类可能会越来越依赖辅助生殖技术。 Chris Willx: 询问睾酮对男性健康、寿命和生育的重要性;询问睾酮和精子数量之间的关系;询问过去65年来精子数量的统计数据和轨迹;询问哪些国家精子数量下降的速度较慢;讨论生育率下降的原因,包括性欲下降等因素;询问人们接触内分泌干扰物的途径;询问如何避免食物中的内分泌干扰物;询问不同类型的塑料对人体健康的影响;询问高质量的净水器能否有效去除水中的污染物;询问内分泌干扰物对行为的影响;询问内分泌干扰物是否会改变性别认同;询问现代社会中女性和男性年龄与生育成功率或生育能力之间的关系;询问未来生育能力的走向。
