Only within the past few years have the general phenomena of intersexuality been cleared up to any considerable extent—naturally on the basis of the secretory explanation of sex. This secretory or endocrine idea has also given us an entirely new view of sex differences. These are best discussed as functional rather than as structural. To correlate this material, we must next give a rude sketch of the quantitative theory of sex.
