In which part of the reproductive system are eggs fertilized?

Eggs are fertilized in the fallopian tube, which serves as the site where sperm meets the egg after ovulation. When an ovum is released from the ovary during a menstrual cycle, it enters the fallopian tube. Should sperm be present in the fallopian tube at that time—often due to sexual intercourse prior to ovulation—fertilization can occur.

The ovary is responsible for producing and releasing eggs but is not the site of fertilization. The uterus, while essential for the implantation and development of a fertilized egg, is not where the fertilization itself takes place. The cervix acts primarily as the passage between the vagina and the uterus, and it plays a role in facilitating sperm entry but is also not involved in fertilizing the egg. Therefore, the fallopian tube is specifically designed for this critical process, making it the correct answer.
