Figure 2.

Kinetic parameters of pattern ‘6' tracks. A single representative track of pattern ‘6' is shown in the inset which curvilinear velocity (VCL, filled line), linearity (LIN, dashed line) and wobble (WOB, dotted line) were determined before (black) and after (red) the cell turned back (green arrow) to the progesterone well and as a function of time. The average values from 27 sperm tracks expressing pattern ‘6' are shown in the bottom of the figure, and correspond to both parts of the track (before and after turning) as a function of time. ^bP<0.05, compared with before turning. Data are expressed as the mean±s.e.
