The fractal dimension of human sperm flagellar curves is used to look up for features pointing to hyperactivation movement. The original 2D fractal dimension formula is directly extended to calculate its 3D counterpart, by means of the Katz Fractal Dimension formula. For each spermatozoon a time-distribution of the flagellar fractal dimension is produced. A distribution is obtained to analyze the time-mean flagellar fractal dimension, and two clear clusters appear that hints to some sperm cells having hyperactivated movement.

摘要

The fractal dimension of human sperm flagellar curves is used to look up for features pointing to hyperactivation movement. The original 2D fractal dimension formula is directly extended to calculate its 3D counterpart, by means of the Katz Fractal Dimension formula. For each spermatozoon a time-distribution of the flagellar fractal dimension is produced. A distribution is obtained to analyze the time-mean flagellar fractal dimension, and two clear clusters appear that hints to some sperm cells having hyperactivated movement.
