Abstract

The original article contains a typographical mistake in the formula notation for the volume of the sperm mitochondrial helix. In the discussion (paragraph 6), we refer to the formula as 'ν = (1/3)π(r2)T'; however, the formula used in our calculations was 'ν = π(r2)T', where π(r2) is the mitochondrial cross-section area and T is the straightened helix length. The latter formula can be expanded to 'ν = (1/3)π(r12 + r1 r2 + r22)T' to describe a truncated cone, where r1 and r2 are the radii at either end of the truncated cone. We refer to this formula in our electronic supplementary material where we show that the trade-off between thickness and length persists irrespective of the degree of taper in the mitochondrial helix. This error does not impact any of the data, analyses, results or conclusions of our paper.
