Ovulation itself typically lasts for about 12 to 24 hours, which is the time the egg remains viable after being released from the ovary. The actual release is momentary, but the egg can survive in the fallopian tube for up to 24 hours if not fertilized. However, the broader fertile window, when pregnancy is possible due to the lifespan of sperm in the female reproductive tract, spans about 5-6 days including the days leading up to ovulation and the day of ovulation itself.
Details on Ovulation Duration
- Ovulation happens once per menstrual cycle, generally about 14 days before the next period.
- The egg's viability post-release is about 12 to 24 hours.
- Although ovulation lasts only this short time, sperm can survive up to 5 days, making the fertility window approximately 6 days.
Fertile Window
- The highest chance for conception is during the day of ovulation and the three days prior.
- This is because sperm can reside in the reproductive tract for several days, ready to fertilize the egg when it is released.
Signs and Tracking
- Changes in cervical mucus, basal body temperature, and hormonal tests can help track ovulation.
- Ovulation symptoms subside after the egg is released and the fertile window closes.
In summary, ovulation lasts about 12-24 hours, but fertility is influenced by sperm longevity, which extends the fertile window to about 6 days each cycle.
