About Reproductive System
The reproductive system covers the male and female reproductive organs, gamete formation, the menstrual and ovarian cycles, fertilization, implantation and pregnancy. It explains the roles of FSH, LH, oestrogen, progesterone and testosterone, while distinguishing spermatogenesis from oogenesis and the reproductive organs from the accessory glands.
