Scientists report that sperm counts have declined over the last 50 years and that environmental factors are to blame. Getting adequate zinc is sometimes the answer. In one trial, 22 men with low testosterone levels and sperm counts were given zinc every day for 45 mg to 50 mg days. Testosterone levels and sperm counts rose.
科学家表示，男性精子数量在近50年来不断下降，环境因素的影响难辞其咎。摄取足量的锌有时可以解决问题。在一项试验中，22个睾丸激素和精子数量较低的男性每天食用45至50毫克的锌，之后其睾丸激素和精子数量均有所提高。
