Examination of coagulation factors in menstrual fluid collected from women with normal menstrual blood less (less than 80 ml) showed the absence of thrombin generating enzymes. Factor X, pro-thrombin and free thrombin were absent from menstrual fluid. No difference was found between days 1 and 2 of menstruation. Thus activation of coagulation enzymes occurs during normal menstruation though the menstrual blood is characteristically fluid.
对月经血量正常偏少(少于80毫升)的女性收集的月经液中的凝血因子进行检测,结果显示不存在凝血酶生成酶。月经液中不存在因子X、凝血酶原和游离凝血酶。月经第1天和第2天之间未发现差异。因此,尽管月经血的特点是呈液态,但在正常月经期间会发生凝血酶的激活。
