许多男性参加马拉松长跑以改善他们的健康状况,但据New Engl J Med新近发表的一项研究称,这项运动可能改变他们的激素水平。密执安大学Susan MacConnie对6名男性受试者进行了观察。这些人在过去5年中每周至少跑125公里并且在不超过2小时45分钟的时间跑完全程。这些长跑者无任何性疾病,但最后都有可能引起睾丸萎缩的激素异常。 Many men participate in marathon long-distance running to improve their health, but according to a recent study by New Engl J Med, the sport may change their hormone levels. Six male subjects were observed by Susan MacConnie of the University of Michigan. These people have traveled at least 125 kilometers per week for the past five years and have completed their journey in no more than 2 hours and 45 minutes. These long distance runners do not have any sexual problems, but in the end they all may have hormonal abnormalities that cause testicular atrophy.
