determine whether the ovum of any succeeding period is male or female. 

It should be noted, however, that the periods are regulated by the lunar 

months, and not the calendar months. The fact that twins of different 

sexes are sometimes born would seem to disturb this theory--but not more 

than any other theory of sex-determination voluntarily produced, for 

that matter. The several schools explain this apparent discrepancy by 

the familiar saying that "exceptions prove the rule." 

 

Another theory of sex-determination is that which holds that when 

conception occurs within a few days after the last day of menstruation, 

the child will be a girl; and that when conception occurs at a later 

period, the child will be a boy. Methods and systems based upon this 

theory are also reported as being reasonably successful in producing 

satisfactory results. But, inasmuch as there appears to be a great 

difference in individual women in this respect (even according to the 

claims of this school of sex-determination), it would seem that it would 

be difficult to proceed with certainty in the matter in most cases. One 

of the writers advocating this method, says: "Conception within five 

days after the end of the menstrual period is almost certain to produce 

a girl child; within five days to ten days, it may be either a boy or a 

girl; from ten to fifteen days, it is almost sure to be a boy; from 

eighteen to twenty-five days is the period of probable sterility, in 

which conception is extremely unlikely to occur." 

 

In conclusion, it may be said that Nature undoubtedly has certain rules 

of sex-determination which govern in these cases; and that it is 

possible if not indeed probable that these rules may some day be 

discovered by man, and turned to account; but that it is very doubtful 

whether the secret has as yet been solved by the investigators. The 

writer may be pardoned for suggesting that, in his opinion, if the 

discovery is ever made it will likely be found to be very simple--so 

simple that we have probably overlooked it because it was in too plain 

sight to attract our attention. Nature's methods are usually very 

simple, when once discovered. She hides her processes from man by making 

them simple, it would seem.
