The purpose of this study was to compare various seminal plasma parameters in fresh human ejaculates exhibiting different amounts of coagulum. Poorly coagulating samples demonstrated significantly lower osmolality and buffering capacity but had a higher pH than did samples with good coagulation. However, no correlation was obtained between the activity of superoxide dismutase and the amount of coagulum. Eight hours after ejaculation, sperm motility had decreased by 15 and 80% in samples with good and poor coagulation, respectively. It is suggested that subfertility may be associated with poor coagulation of ejaculates.
本研究的目的是比较新鲜人类精液中呈现不同量凝固物的各种精浆参数。凝固不良的样本显示出明显较低的渗透压和缓冲能力，但pH值高于凝固良好的样本。然而，超氧化物歧化酶的活性与凝固物的量之间未发现相关性。射精8小时后，凝固良好和不良的样本中精子活力分别下降了15%和80%。提示生育力低下可能与精液凝固不良有关。
