Human reproduction is the process by which new individuals of the human species are produced. It involves the fusion of a sperm cell from the male and an egg cell from the female, forming a zygote. The zygote develops into an embryo, which grows within the mother’s uterus during pregnancy. After a gestation period, childbirth occurs, resulting in the delivery of a baby. Human reproduction is facilitated by the reproductive organs, hormones, and complex physiological processes necessary for fertilization, embryonic development, and childbirth.
