The activity of spermatozoa of albino rats (Rattus norvegicus) which were taken from the testis and epididymis was observed after the application of the following solutions and extracts: 0.272M Nacl, 0.136M NaCl, 0.068M Nacl, glucose solution, Gey's saline, rat serum, testis extract and epididymis extract. The mixtures of spermatozoa and solutions or extracts were enclosed in micro-glass capillaries and observed with the aid of phase optics. The testicular spermatozoa showed little movement and slight activity in all solutions or extracts under examination, while the epididymal spermatozoa showed active movement under the same treatment, except the cases with glucose and hypotonic NaCl solutions. There are three types of sperm movement as follows: advance type, rotation type, and pendulum type. It was found that Cey's solution was favourable for activation of spermatozoa, and that the spermatozoa showed the highest longevity in the testis extract.
