Photoelectric and Cinematographic Measurements of the Motility of Bull Sperm Cells

摘要

A method is described for investigating the motility of bull sperm cells, by means of a photoelectric device and by moving films. A description is given of the normal type of movement of sperm cells, and of a pathologic type of movement, both investigated cinematographically. The information from the photoelectric method and the accuracy of the data obtained are discussed.
