Sex

Sex is a biological process through which organisms reproduce, involving the combination of genetic material from two parents. In humans and many other species, sexual reproduction typically involves the fusion of male and female gametes (sperm and egg), resulting in offspring with genetic contributions from both parents. This process not only facilitates reproduction but also promotes genetic diversity, which is crucial for the adaptation and evolution of species. In addition to its biological functions, sex has social, emotional, and cultural dimensions that vary widely across different societies.
