Twenty males underwent transrectal ultrasonography before and after ejaculation to examine possible alterations that could influence interpretation of seminal vesicle ultrasonography. The preejaculation length of 35 mm was significantly (p < 0.05) decreased to 30 mm after ejaculation. The mean width of the seminal vesicles was 13 mm before and 11 mm after ejaculation. The seminal vesicle volume was significantly diminished after ejaculation (p < 0.05). It therefore seems important to maintain a period of abstinence when evaluating the seminal vesicles by ultrasonography.
20名男性在射精前后接受了经直肠超声检查，以探究可能影响精囊超声检查结果解读的变化。射精前精囊长度为35毫米，射精后显著缩短至30毫米（p < 0.05）。射精前精囊平均宽度为13毫米，射精后为11毫米。射精后精囊体积显著减小（p < 0.05）。因此，在通过超声检查评估精囊时，保持一段禁欲期似乎很重要。
