Table 2. Percentage (± SE) of two- and three-dimensional measurements of the non-sexed (NS), pool of the sorted for X and Y (SXY), X-bearing sperm (SX) and Y-bearing bovine sperm (SY).

Groups	Measures of structural characteristics
	Two dimensional			Three dimensional
	Perimeter (µm)	Area including hole (µm²)	Surface area (µm²)	Volume (µm³)
NS	28.4±1.55	46.4±5.0	46.9±4.97	13.7±1.44
SXY	28.3±0.65	46.5±5.4	47.1±1.66	13.2±0.65
SX	29.9±2.25	49.0±7.7	49.6±7.68	14.4±1.71
SY	28.9±1.59	48.9±5.3	49.4±5.32	14.9±2.68

Values are an average of at least 400 sperm for each group. There was no difference between groups (P>0.05).
