While prostatic manipulation and surgery have been shown to increase serum prostate specific antigen (PSA), the influence of ejaculation on serum PSA remains controversial. We examined the effect of ejaculation on serum PSA levels.
We evaluated 100 men 25 to 35 years old with no history of surgery or inflammatory disease of the urogenital tract. Serum PSA was evaluated 1 and 24 hours after ejaculation, and serum testosterone and seminal fluid PSA levels were determined.
In all men a baseline PSA level was detected. There were no statistically significant changes in serum PSA and testosterone 1 and 24 hours after ejaculation. Mean PSA concentration was significantly higher in seminal plasma than in serum. However, we did not observe a correlation between serum and seminal plasma PSA levels.
Based on our data ejaculation does not affect serum PSA concentration in young men, and there seems to be no physiological relationship between ejaculation and PSA level.
虽然前列腺按摩和手术已被证明会使血清前列腺特异性抗原（PSA）升高，但射精对血清PSA的影响仍存在争议。我们研究了射精对血清PSA水平的影响。
我们评估了100名年龄在25至35岁之间、无手术史或泌尿生殖道炎症疾病史的男性。在射精后1小时和24小时评估血清PSA，并测定血清睾酮和精液PSA水平。
所有男性均检测到基线PSA水平。射精后1小时和24小时，血清PSA和睾酮无统计学显著变化。精液中PSA的平均浓度显著高于血清中的PSA。然而，我们未观察到血清和精液中PSA水平之间的相关性。
根据我们的数据，射精不影响年轻男性的血清PSA浓度，射精与PSA水平之间似乎不存在生理关系。
