Sex

Sex, in biological terms, refers to the process by which organisms combine genetic material to produce offspring. In humans and many animals, sexual reproduction typically involves the union of male and female gametes (sperm and egg) through copulation or mating. This process increases genetic diversity within a population. In addition to its reproductive function, sex in humans often has social, emotional, and recreational aspects. Sexual behavior varies widely across species and cultures. For more information, see the Wikipedia entry on Sexual intercourse.
