The document provides information about the male and female reproductive systems. It describes the main organs involved in both systems, including their locations and functions. Some key facts are presented, such as that fertilization typically occurs 14 days after the start of a woman's menstrual period. The zygote is formed after the union of an egg and sperm. Pregnancy lasts approximately 260 days or 9 months and is divided into three stages called trimesters. The male system produces and stores sperm and secretes hormones while the female system transports eggs, provides a place for fertilization and gestation, and gives birth.
