Dr. Heward explains the role hormones play in sexual attractiveness.
Sexual attractiveness is probably the key element in evolutionary biology. You can sum up the evolution and the mechanisms that drives evolution not as survival of the fittest, but survival of those things that reproduce. I mean fitness, evolutionarily speaking, is defined in terms of reproduction. Those things that reproduce better, we get more of.
So imagine all those guys in our evolutionary history that were attracted to post-menopausal women. Where do you suppose their offspring are? Where are they? There aren’t any. Why? Because they’re post-menopausal. So we are evolutionarily geared to be attracted to pre-menopausal women, young, fertile women.
What is the characteristic that segregates the population of women who are young and fertile versus post-menopausal? The presence of estrogen and the impact of that estrogen on their bodies in ways that we don’t even know and understand and yet, you and I can see by just looking at a woman who is enjoying the benefits of estrogen and comparing that person to a woman who is estrogen-deprived. We can tell the difference, and the woman without estrogen is absolutely not as attractive, and for good reasons biologically.
