由于这些周期,雌性在排卵后会产生卵子,而卵子必须由雄性精子受精。这只能发生在交媾之后,也就是男性和女性性交之后。在此过程中,雄性会将其精子释放到雌性体内,雌性会前往卵子并使其受精(Boesch, Hohmann和Marchant, 2002)。卵子受精后,会附着在女性的子宫壁上,在完成妊娠期后,新生婴儿就会出生。几乎所有灵长类动物都是如此。但人类同时也被称为性灵长类动物,这两种行为之间存在显著差异,使得智人的性行为独一无二。

在灵长类和智人身上,性最重要的意义在于它们必须通过繁殖后代来繁衍后代,为了繁殖后代,它们必须有性行为。但从灵长类动物到人类,性别的重要性各不相同。性在最重要的性别中被称为有用的,记住几乎所有的动物都是有性的。这是因为新生儿或后代的遗传多样性会随之增加这让进化过程变得迅速更重要。因此,性对于包括智人(Crow, 2002)在内的所有动物来说都是非常重要的。

Owing to these cycles, the females produce eggs after ovulation, which has to be fertilized by the male sperm. This can only happen after copulation that is after the sexual intercourse between the male and the female. During this, the male releases its sperm in the female which travels up to the egg and fertilizes it (Boesch, Hohmann and Marchant, 2002). After the egg is fertilized, it attaches itself to the uterus wall of the female and on completing the gestation period a new born takes birth. This is true in almost all the primates. But human beings at the same time are known as the sexual primates, and there is a notable difference between the behaviour displayed by the two making sex for Homo sapiens unique.

The most important significance of sex in primates and in Homo sapiens is the fact that they have to reproduce and continue their line by producing offspring’s of their own kind, and for reproduction they have to engage in sex. But the importance of sex varies when one moves from primates to the human beings. Sex in the most significant sex is termed to be useful, keeping in mind that almost all the animals are sexual. And it is because the genetic diversity in the new-borns or the off-springs increases with this and it permits rapid and more importantly the evolutionary changes. Thus, sex is important at a general level for all animals including the Homo sapiens (Crow, 2002).
