Where does fertilization normally take place in the human female reproductive system?

1. After copulation, sperms travel along the route vagina, then uterus, then oviduct. 2. The released ovum is present in the oviduct. 3. One sperm fuses with the ovum there, so fertilization occurs in the oviduct. 4. The vagina and uterus are only passages or the site of implantation, and no ovum is fertilized in the ovary, so those are ruled out. _Source: Balbharati (Maharashtra Board) Class 10 Science & Technology Part 2, Ch 3 "Life Processes in Living Organisms Part 2", p.38_
