Studies in the Physiology of Spermatozoa
Edwin J. Cohn
(1919)
I. Introduction
The changes in the physiological condition of the spermatozoon, from the time it is extruded from the genitalia of the male until it "undergoes the transformation into a nucleus" (Loeb, J., I9I3, p. 306) in the protoplasm of the egg are dependent in rate upon environmental conditions. The germ cells of most marine invertebrates are extruded into sea water, and fertiliza- tion of the egg by the sperm there follows.' The environment, sea water-or sea water modified by the excretions of the egg or of the sperm-must therefore be studied in order to understand the variations in the physiological condition of spermatozoa that have often been observed.
