Abstract
Purpose : Prostatic manipulation and surgery have been shown to increase serum prostate-specific antigen (PSA). We studied the effect of ejaculation on the serum PSA levels.
Materials and Methods : We evaluated 131 men(16 to 64 years old) who had no history of surgery or inflammatory disease of the urogenital tract. The total serum PSA, free PSA, serum total testosterone, free testosterone, luteinizing hormone(LH), and follicular stimulating hormone(FSH) were evaluated 1 hour after ejaculation.
Results : A PSA level was detected in all the men. There were statistically significant changes of the serum PSA level before and after ejaculation. We compared the parameters between increased PSA group and the decreased PSA group. There were significant differences between the two groups on comparison of the total prostate volume(25.4±3.6g vs 15.1±4.2g, respectively) and the transition zone volume(7.1±2.7g vs 5.3±1.1g, respectively).
Conclusion : Based on our data, ejaculation affects the serum PSA concentration in young men, and there seems to be a physiological relationship between ejaculation and the PSA level. The larger the prostate volume, the more ejaculation has an effect on the serum PSA level. (Korean J Urol 2007;48:1247-1250
