  1. Results are expressed as means ± standard error of the mean (SEM; n = 6). The results showed that 5 µM 17-AAG significantly inhibited human sperm hyperactivation (*P < 0.05). VSL straight line velocity; VCL curvilinear velocity; VAP average path velocity; STR straightness (VSL/VAP multiplied by 100); LIN linearity (VSL/VCL multiplied by 100); ALH amplitude of lateral head displacement; and BCF beat-cross frequency
