Collagen-induced platelet aggregation was studied under well defined experimental conditions in female volunteers on the 6th and 20th days of the menstrual cycle. In addition, another group on long-term contraceptives was investigated. The two parameters studied were the maximum amount and velocity of aggregation. In these three groups no significant changes were found in the parameters studied, and influences of the menstrual cycle and contraceptives on platelet aggregation are therefore unlikely.
在明确的实验条件下，对处于月经周期第6天和第20天的女性志愿者的胶原诱导血小板聚集情况进行了研究。此外，还对另一组长期服用避孕药的女性进行了调查。所研究的两个参数是最大聚集量和聚集速度。在这三组中，所研究的参数未发现显著变化，因此月经周期和避孕药对血小板聚集的影响不太可能存在。
