In many species, the males develop elaborated sexual traits to attract females and dissuade potential rival males through competition. Some iconic examples are the extraordinary feathers of the peacock or paradise birds, or the menacing antlers of dominant red deer males. But how is the role of each sex determined in nature? Why do males generally compete for access to females? Researchers believe the answer lies in what is known as the Bateman principle , which suggests that sexual selection acts with more intensity in the sex that invest less in the offspring. Parental investment was proposed in by the American evolutionary biologist Robert Trivers as a key factor determining which sex is under higher sexual selection pressure.

But are they right? That claim might sound strange. It goes like this:. There are exactly two kinds of people. One kind, men, have a penis, testes, and XY chromosomes, and the other kind, women, have a vulva, uterus, breasts, and XX chromosomes. Everyone is one or the other. Men and women have different character traits that follow naturally from their different bodies, and therefore are suited to different social roles. It ensures that men on the whole have greater power, opportunity and status compared to women. On top of this, many people have a subjective sense of themselves as men, women, some other gender, or none at all, known as gender identity. Trans people are people whose gender identity is different from the way they were categorised as male or female at birth based on their body.

Researchers from the University of Zurich in Switzerland first asked a group of women, ranging in age from 16 to 45, to look at pictures of male genitalia and rate how "normal looking" they found each penis to be. Next, the penis oglers answered questions about which penile qualities they considered most important when assessing the attractiveness of a man's package. Specifically, subjects were asked to rate the following attributes in order of importance: length of the penis, girth of the penis , position and shape of the meatus the opening where certain fluids come out , shape of the glans the rounded tip or head of the penis , appearance of the scrotum, appearance of the skin on the penis, appearance of pubic hair and the overall cosmetic appearance of the penis.
