Introduction
After ovulation, the egg remains viable for 12–24 hours. Once released, the egg is captured by the fimbriae of the fallopian tube and transported into the tube. Peristaltic contractions of the fallopian tube then carry the egg to the ampulla—the widest section of the tube—where it typically remains for 1–3 days. If sperm encounter the egg within this 24-hour window after ovulation, fertilization can occur.
Many people hoping to conceive as soon as possible choose to have intercourse during the ovulation period, since the ovaries release an egg (ovum) at this time—thereby increasing the chances of pregnancy. But how long does the egg survive after ovulation?
How long does an egg survive after ovulation?
After ovulation, the egg remains viable for approximately 12–24 hours. Once released, it is captured by the fimbriae of the fallopian tube and transported into the tube. Through peristaltic contractions, the egg travels to the ampulla—the widest section of the fallopian tube—where it typically remains for 1–3 days. If sperm encounter the egg within this 24-hour window, fertilization can occur. Even if sperm enter the female reproductive tract slightly before or after the egg’s release, a series of biochemical reactions may still enable fertilization, resulting in formation of a zygote.
The egg’s survival time is generally about 1–3 days, though in some cases it may persist longer. Therefore, intercourse occurring 1–3 days before or after ovulation also carries a chance of conception—closely linked to the egg’s viability window.
Thus, women attempting to conceive should carefully track their monthly ovulation period. Intercourse around the mid-cycle—specifically 1–2 days before and after ovulation—offers the highest likelihood of pregnancy. We hope this information is helpful to you.
