Sperm can survive for 2-3 days in the fallopian tube.
The duration and survival rate of sperm will directly affect the fertilization rate. The longer the sperm survives, the higher the chance of meeting the egg cell to complete fertilization. On the contrary, a short sperm survival time will result in a lower fertilization rate and may even cause infertility due to low sperm survival and short survival time.
Despite the short survival time of sperm outside the body, which is about 1 hour or so, when the sperm enters the woman’s body, the survival time will be greatly extended, and it can usually survive in the lumen of the fallopian tube for 2-3 days. The egg can also survive in the body for 24 hours after it is discharged. Therefore, if a woman has not yet ovulated and has intercourse in advance, the chances of conception can be increased.
To summarize, sperm can survive in the fallopian tube for 2-3 days. For couples who are preparing for pregnancy, it is recommended to have intercourse 1-3 days before or after the woman’s next ovulation to help prepare for pregnancy.
