Reproduction

Abstract

Human reproduction, as everyone knows, is of the sexual variety. The process begins with the formation of eggs (ova) in the female ovaries and of spermatozoa (sperm) in the male testes. In the act of sexual intercourse, if it occurs at the right time, the two are brought together and the fertilized egg or zygote results. This becomes implanted in the uterus which has been prepared for its reception and develops over approximately 280 days in normal circumstances to a fully formed infant. In the process of labour (parturition), the infant is pushed into the outside world and the cycle normally ends with the feeding of the infant with milk from the mother’s breasts.
