寿命延长可能是导致人类精子数量减少的主因

Extension of lifespan plays a major role in the reduction of human sperm count

近年来人类精子数量的下降已成不争的事实并受到广泛关注。有意思的是,对于这一重要的问题全世界似乎很有共识——那就是,环境污染惹的祸。实际上略经分析就可知道,这种共识非常不靠谱。其实,生殖力与寿命相互消长是自然界的规律。精子数量的下降,只不过是人类寿命延长的必然。

Human sperm count reduction has been under the spotlight in recent years. The tunny thing is that all over the world people take it for grant that environmental pollution is responsible for the reduction. Actually, it is not hard to figure out that such a consensus is logically and scientifically groundless. The true cause which may really account for the speml count reduction is the extension of human lifespan.
