In women, chronic and intense endurance exercise is frequently associated with menstrual cycle alterations. In men, the effects of similar amounts of exercise are less well-studied. We tested the hypothesis that endurance exercise in men is also associated with alterations in reproductive function. We studied 12 marathon runners and 12 age-matched, lean controls; serum and semen samples were collected every 2 weeks for 12 weeks. Sperm counts, sperm morphologies, and mean levels of testosterone (T), free T, sex hormone binding globulin, cortisol, follicle-stimulating hormone, and biologically active luteinizing hormone (LH) were similar in the two groups. Mean levels of immunologically active LH were somewhat higher in the marathoners. We conclude that this level of strenuous, long-term endurance exercise does not have major adverse effects on reproductive function in men.
在女性中，长期剧烈的耐力运动常与月经周期改变有关。在男性中，同等运动量的运动效果研究较少。我们检验了男性耐力运动也与生殖功能改变有关这一假设。我们研究了12名马拉松运动员和12名年龄匹配的瘦对照者；在12周内每2周采集一次血清和精液样本。两组的精子计数、精子形态以及睾酮（T）、游离T、性激素结合球蛋白、皮质醇、促卵泡激素和生物活性促黄体生成素（LH）的平均水平相似。马拉松运动员中免疫活性LH的平均水平略高。我们得出结论，这种高强度、长期的耐力运动对男性生殖功能没有重大不利影响。
