Fertilization of the ovum typically occurs within 24 hours after ovulation, when a mature egg is released from the ovary. Sperm must reach the egg during this window to successfully fertilize it, usually taking place in the fallopian tubes. Once a sperm penetrates the egg, fertilization is complete, resulting in the formation of a zygote. This process marks the beginning of embryonic development.
