Usually sperm survive for 2-3 days, and if they do not unite with the egg to form a fertilized egg, they will die naturally, so knowing the time of sperm survival, it is recommended to schedule specific intercourse times in your daily life to decide whether to get pregnant or give birth control. For example, if you are planning to get pregnant, calculate your ovulation time and then have intercourse. Depending on the sperm survival time, having intercourse two days before ovulation, on the day of ovulation, and the day after ovulation will increase your chances of getting pregnant. If you are not planning to get pregnant, you should calculate the time of ovulation and have intercourse outside the ovulation period or use condoms to avoid pregnancy.
