The length of time an egg can survive in the body is dependent on the individual’s body type and can usually survive 1-2 days. A woman can ovulate approximately 400-500 times in her lifetime. After the egg is expelled from the ovary, it is picked up by the umbilical end of the fallopian tube and then waits in the fallopian tube to meet the sperm. If the egg meets the sperm, it may combine to form a fertilized egg; if it does not, it will age and die 1-2 days after ovulation. However, there is some individual variation in the exact duration of the egg’s survival in the body, some for a shorter time, some for a longer time, and even up to 5-7 days have been reported. It is recommended that women who are preparing for pregnancy should arrange intercourse during the ovulation period, i.e. from 5 days before to 4 days after ovulation, so that they can have intercourse every other day to improve their chances of conception. You need to pay attention to the combination of work and rest, avoid overexertion, and increase diet and nutrition appropriately.
