AFM of normal human spermatozoa. a. 2D image (8.00 × 8.00 μm scan) of normal sperm head. b. Height profile of the head region of spermatozoa showing clear difference in the head and the acrosomal region. c. Power spectrum of the above profile showing the scaling of roughness. d. Histogram plot of the height of the head region. e. 3D image of the head region of the spermatozoa.
