About Reproductive Anatomy and Conception
Female and male reproductive organs, pelvic anatomy, gametogenesis, the menstrual cycle and the hormonal control of ovulation lead into fertilisation, implantation and early embryonic development. Questions distinguish ovulation from menstruation, fertilisation from implantation, and the normal anatomical changes that allow conception and pregnancy to occur.
