  • a UF, ultrafiltrate; MF, mount frequency; IF, intromission frequency; IL, intromission latency; EL, ejaculation latency; PEI, postejaculatory interval. Each parameter was compared with rats after injection of the same volume of normal plasma ultrafiltrate (n = 6) or saline (n = 8), using the paired t test. Data are mean ± SEM.
