The motility of spermatozoa in a large amount of spermatic fluid

Measurement of the spermatozoal velocity indicated that the average motility in 111 ejaculates with volumes of more than 6 ml after 1 and 5 hours after ejaculation was highly significantly lower (p less than 0.01) than in the control group. The latter consisted of 166 ejaculates with volumes of less than 6 ml. The percentage of morphologically defective spermatozoa was practically identical for both groups and the difference in the decrease in motility of the spermatozoa 5 hours after ejaculation was statistically non-significant.
