Seminal fluid parameters of ejaculates collected via masturbation successively after sixty minute interval were compared. Volumes of semen were in most cases significantly lower in the second ejaculations as compared with the first. Sperm density was higher in the second specimen only in 32 patients (31% of the group). The percentage of motile spermatozoa was comparable in both specimens. The velocity was in the second specimens significantly lower. The percentage of morphologically defective forms of spermatozoa was found to be approximately the same in both specimens. The use of successive ejaculation will have hardly any greater clinical importance in the treatment of hypofertile men.
对通过手淫每隔60分钟连续采集的精液样本的精液参数进行了比较。在大多数情况下，第二次射精的精液量明显低于第一次。仅32例患者（占该组的31%）的第二次样本中的精子密度较高。两个样本中活动精子的百分比相当。第二次样本中的速度明显较低。发现两个样本中形态有缺陷的精子形式的百分比大致相同。连续射精在治疗生育能力低下的男性方面几乎没有更大的临床意义。
