Probability distribution P of the rotation angle ϕ of the beating plane around the flagellar axis, where ϕ = 0° corresponds to parallel orientation to the wall. Data are shown for MCE sperm with small (c0(m)Lm = 0.07; pluses), medium (c0(m)Lm = 0.7; crosses), and large (c0(m)Lm = 0.9; stars) preferred midpiece curvatures. The distribution for c0 = 0 is symmetric at ∼ϕ = 90° and ϕ = 180°.
