Murine I Cs + densities (mean values S.E.M.; pA/pF) from CatSper1 +/+ sperm obtained at 80 mV and + 80 mV at 24 C, 28 C, 32 C, and 38 C ( n = 9), as well as the same cells’ I Cs + densities obtained after cooling (reversal). I Cs + densities obtained at 80 mV were as follows: 143.54 11.86 (at 24 C); 162.20 17.17 (at 28 C); 194.44 19.54 (at 32 C); and 271.81 19.97 (at 38 C). Reversal I Cs + density at 80 mV was 134.79 16.32; n = 3. I Cs + densities obtained at + 80 mV were as follows: 222.93 13.16 (at 24 C); 245.84 16.31 (at 28 C); 278.37 17.66 (at 32 C); and 340.85 24.48 (at 32 C). P- values for both outward and inward current densities were < 0.0001.
