Each episode opens panning across a sea of naked bodies starting with infants on their backs and ending with older people. Some genitals and breasts are clearly visible while some younger children's private parts are blurred out. Presented in a anthropological rather than a sexual way.
Episode 1 shows a nude side profile of a pregnant woman. Breasts and pubic area are plainly visible. Episode 4 shows a close-up of a prepubescent boy's genitals morphing into a man's with pubic hair.
