To determine the effects of ejaculation on serum PSA, we measured serum levels just before masturbation and 24 hours and 5 days later in a study group (n=25) aged between 23 and 25 years. In the study group, 16 cases showed a decrease (mean 22.37%, range 10-50%) in serum PSA levels 24 hours after ejaculation, while 6 had higher levels (mean 38.33%, range 21-67%) and 3 had no changes. No relation was found between seminal plasma levels or total amounts expelled of this marker and the difference in serum levels due to ejaculation. In the control group free of ejaculation in the same period determinations of serum PSA levels revealed no significant changes between days 0, 1 and 5. As compared with the control group, the changes in the study group were found to be statistically insignificant. These results may indicate that ejaculation has an insignificant effect on serum PSA levels.
为了确定射精对血清前列腺特异性抗原（PSA）的影响，我们在一个年龄在23至25岁之间的研究组（n = 25）中，测量了手淫前、射精后24小时和5天后的血清水平。在研究组中，16例在射精后24小时血清PSA水平下降（平均22.37%，范围10 - 50%），6例水平升高（平均38.33%，范围21 - 67%），3例无变化。该标志物的精浆水平或排出总量与射精引起的血清水平差异之间未发现关联。在同期无射精的对照组中，血清PSA水平在第0、1和5天之间无显著变化。与对照组相比，研究组的变化在统计学上无显著意义。这些结果可能表明射精对血清PSA水平影响不大。
