Question

Quizplus · Accepted Answer

Fertilization occurs in the upper third of the uterine tube, which is also known as the ampulla. Sperm can survive in the female reproductive system for up to five days, so fertilization can occur several days after ovulation. However, it is most likely to occur within 24 hours of ovulation. Fertilization does not occur in the ovary or the uterus.
