Testosterone reduces the intracellular Ca²⁺ levels in DSM cells. A: original recording showing a decrease in the global intracellular Ca²⁺ concentration by 100 nM testosterone in a DSM cell. B: summary data demonstrating the significant decrease in global intracellular Ca²⁺ concentration by 100 nM testosterone (n = 8, N = 5; *P < 0.05). Data are reported as the ratio of fura-2 AM fluorescent emission at 510 nm with excitation at 340 and 380 nm.
