Active transport system in human spermatozoa.
The presence of potassium influx into human spermatozoa was investigated through the use of radioactive K42 and Rb86. A gradient of potassium and sodium has been found between the spermatozoal midpiece-tail region and seminal plasma. The influx of potassium seemed to correlate with spermatozoal motility.
