SEXUAL REPRODUCTION

The process of producing new generation to continue the existence of a species by the fusion of two cells from different individuals;this is achieved in humans by fusion of one sperm and one ovum.this fusion calld fertilization,is achieved by sexual intercourse or artificial insemination.

Reproduction is facilitated by the reproductive system, a group of organized structures that can be subdivided into male and female reproductive systems.During puberty, which typically occurs between the ages of 10 and 14 years, the reproductive systems of both sexes mature. This phase is marked in part by the release of eggs (female sex cells) in the female ovary and the formation of sperm (male sex cells) in the male testes. Reproduction can take place only when a sperm unites with an egg, a process called fertilization.
