The spermatozoal volume as indicative of the plasma membrane integrity (modification of the hypoosmotic swelling test). II. Diagnostic approach.
If using a method of statistical sifting based on the Kolmogoroff-Smirnov test for differentiation of volume distribution curves of a modified HOS-test, different curve types are obtained under isotonic as well as under hypotonic conditions. Arrangement of spermatological parameters of the relevant ejaculates according to the individual curve types reveals significant differences for motility. No correlation can be seen with the results of the microscopic HOS-test. Consequences for the use of the modified HOS-test in medical practice are discussed.
