REPRODUCTION IN MAN 01 



ditions that always obtain in human reproduction, 

 what is their bearing and application? The pro- 

 duction of offspring is a universal process among 

 living things. This process was a part of life 

 from the very beginning and will continue to be 

 inseparable from it to the end of time. There is 

 no way by means of which the ovaries and sper- 

 maries can be prevented from producing their 

 normal products except by certain diseases or an 

 operation resulting in their removal. The repro- 

 ductive process is thus a normal part of life. Re- 

 move it and there would result something different 

 from life as it is everywhere known. It makes no 

 difference whether one is willing to be intelligent 

 upon this vital matter or not, the germ glands con- 

 tinue their normal activity. (Figs. 31, 32, 33.) 



In the same sense that this process is universal, 

 it is a natural and normal vital activity. There is 

 no method known by means of which one can de- 

 termine that a given sperm shall unite with a given 

 ovum. There are thousands of sperms in a single 

 emission but only one enters the o\Tam. Nature 

 must be forever preparing normal sperms or the 

 result would be a failure. This she seems to be 

 able to do in unlimited numbers. If the state- 

 ment that no two sperm-cells are ever identical be 

 true, then there must be a large degree of chance 

 as to which one of the many thousands will be sue-
