How long does it take for an ovulated egg to reach the oviduct in a horse?

• A. 6-12 hours
• B. 24-48 hours
• C. 2-3 days
• D. 4-6 days

Answer: (B)

In horses, ovulation releases the oocyte into the peritoneal cavity near the ovary, and it must be swept into the oviduct by the fimbriae and transported along the oviduct. This capture and transit take time, not minutes, so the egg usually reaches the oviduct about a day to two days after ovulation. That’s why the 24–48 hour window is the best answer. The shorter timeframes imply a faster transfer than what actually occurs, while much longer times would miss the window when the egg remains viable and ready for fertilization.
