Osmolarity was determined same day using a Micro-Sample Osmometer model Fiske [R] 210 and the pH values were measured with a digital pHmeter model pH 21 and the value that were obtained are indicated in Table 1.
The differences among WT and HOST observed in the present study could be explained by the fact that the sperm acts as an osmometer and that the sperm response is proportional to the decrease in external osmolarity [7, 8].
