Human sperm diluted in buffer imaged at room temperature within two hours of ejaculation. Cell at center swims at constant speed.

Technical Details

Sperm were diluted with PBS and plated in a coverslip bottom chamber on an Olympus IX70 with 60X N.A. 1.4 phase 3 optics. Images were collected with an air cooled CCD camera (either Roper Coolsnap or Cooke Sensicam) at 12 bits and converted to 8 bits. The time interval was less than 1 second per image.
