When does fertilization typically occur after ovulation?

Fertilization typically occurs approximately 24 hours after ovulation. This timeframe aligns with the lifecycle of the ovulated oocyte, which is generally viable for about 12 to 24 hours after it is released from the ovary. Sperm can survive in the female reproductive tract for up to five days, so the optimal window for fertilization exists within this period.

After ovulation, the oocyte is captured by the fimbriae of the fallopian tube, where it remains ready for fertilization. If sperm are present during this window, fertilization can successfully take place, leading to the formation of a zygote. Understanding this timing is crucial for comprehending the overall process of conception and the factors that influence fertility.
