ABSTRACT
Several scientists have begun to examine the relation between personality and human reproductive behavior from a gene-based evolutionary perspective…. In this vein we reported a study of racial difference in sexual restraint such that Orientals > whites > blacks. Restraint was indexed in numerous ways, having in common a lowered allocation of bodily energy to sexual functioning. We found the same racial pattern occurred on gamete production (dizygotic birthing frequency per 100: Mongoloids, 4; Caucasoids, 8; Negroids, 16), intercourse frequencies (premarital, marital, extramarital), developmental precocity (age at first intercourse, age at first pregnancy, number of pregnancies), primary sexual characteristics (size of penis, vagina, testis, ovaries), secondary sexual characteristics (salient voice, muscularity, buttocks, breasts), and biologic control of behavior (periodicity of sexual response predictability of life history from onset of puberty), as well as in androgen levels and sexual attitudes. 1
