title: Temperature dependent hysteresis-like changes of motility parameters in human spermatozoa.
abstract: We studied the impact of temperature changes on selected parameters of normozoospermic spermatozoa motility. The examinations were carried out in the temperature range of 11 degrees C to 21 degrees C both during cooling and heating. We found that a phenomenon of hysteresis, i.e. alternate means of changes in velocity straight linear and lateral head displacement was obtained both at cooling and at heating. This phenomenon was not found for other parameters examined.
