  1. Free-swimming sperm from wildtype or heterozygous Prm2Δ 97 or Prm2Δ 101 mice have been analyzed using dark-field microscopy. Data are presented as mean ± S.D.; VCL: curvilinear velocity μm/s), VAP: average path velocity (μm/s); VSL: straight-line velocity (μm/s), LHD: lateral head displacement (μm); STR: path straightness (VSL/VAP).
