EFFECT OF pH ON THE SWIMMING RATE OF BULL SPERMATOZOA

D. TAMPION, R. A. GIBBONS
1963 Reproduction  
Measurements were made of the swimming rate of bull spermatozoa at a concentration of 10,000 cells per µ in physiological saline solution and in saline solution buffered with 0-014 M-phosphate at pH values of 6-5, 7-5 and 8-5. The buffers at pH 6-5 and 7-5 gave re¬ sults similar to those for unbuffered saline solution. At pH 8-5 there was an initial advantage, both in percentage motile and in swimming rate. By the end of 1 hr, the spermatozoa were, however, swimming more slowly, and fewer were
more » ... ly, and fewer were surviving than in any other medium. The significance of these results in relation to the swimming of spermatozoa in the female tract is discussed.
