Further proof that mammalian intercourse ratios at delivery are partially managed by parental hormone

The current note is an endeavor to augment past argument from the hypothesized parental hormonal antecedents of mammalian offspring intercourse ratios. It’s meant that a audience who’s got read both this paper and my past paper ought to be aware of the many data concerning the hypothesis James WH (1996), J Theor Biol 180, 271–286.

Introduction

It is often hypothesized that the sexes of offspring of mammalian (including human) parents are causally pertaining to the hormones levels of both moms and dads round the period of conception.
