Additional quotes by Gad Saad

Men produce hundreds of millions of spermatozoa per day whereas women ovulate at most 400 times between the onset of menarche and the start of menopause. Hence, an ovum is astoundingly more precious than sperm. This inequality in the importance of the male and female gametes drives the differential behaviors of the two sexes. From the perspective of reproductive fitness, a male benefits from engaging in numerous mating dalliances (can impregnate many women with easily reproduced gametes) whereas in light of the dearth of ova women must be extremely judicious in their mating choices. Furthermore, whereas men’s contribution to parenting could be as small as a brief sexual encounter, women bear the costs of gestation and lactation, face the dangers of childbearing (associated with high mortality in the ancestral environment), and are exposed to increased environmental threats associated with reduced mobility when pregnant.
