Summary

B. G. Jefferis and J. L. Nichols Searchlights on Health — Producing Boys or Girls at Will (1919)

CONCEPTION IN THE FIRST HALF of the time between the menstrual periods produces females, and males in the latter.—London Lancet.
8. INTERCOURSE in from two to six days after cessation of the menses produces girls, in from nine to twelve, boys.—Medical Reporter.
THE MOST MALE POWER and passion creates boys; female girls. This law probably causes those agricultural facts just cited thus: Conception right after menstruation give girls, because the female is then the most impassioned; later, boys, because her wanting sexual warmth leaves him the most vigorous.
