There is another term fertile window which describes the six days nearing ovulation and the day of ovulation itself. The chances of getting pregnant heighten if one has sex in the “fertile window.” Sperm can live many days in women’s reproductive tract all set to fertilize egg immediately after its release. As the egg moves into the fallopian tubes, it stays there for 24 hours
Once the egg is in the fallopian tubes, it lives for around 24 hours before it can no longer be fertilized, thus ending the fertile window.
