Physiologists have differed much as to the function of the prostate. The question is reviewed carefully in Walker's recent study of the anatomy and physiology of the prostate gland.1 It has been known for some time that the movement of the spermatozoa is markedly stimulated by the secretion of the accessory sexual glands. All anatomists state that in the testis the spermatozoa are immotile; in ejaculated semen they are all in lively motion. Artificial addition of prostatic fluid to semen taken directly from the testis induced lively motility of the organisms, continuing for twenty-one hours—Steinbach. In order to throw more light on this subject, Walker instituted a series of experiments on dogs, from the results of which it may be concluded that the immediate production of motility of spermatozoa is due to the thinning of the testicular secretion with the prostatic fluid; substances in this fluid, acting either as
