procreation

Procreation is the reproduction of offspring by a sexual process or asexual process. The vast majority of animal species (including humans) reproduce sexually but some reproduce asexually. In other words, procreation in the vast majority of animals is only possible when a male animal and a female animal come together to have sex. This is also known as breeding or mating. Procreation is absolutely necessary for the vast majority of animal species to survive. Animals that reproduce sexually, breed with members of the opposite sex due to a desire for sexual pleasure, love, and the need to propagate the next generation. Heterosexual sex is the only kind of sex that can lead to sexual reproduction.
