Ovulation

Women's ovulation date is generally about 14 days before the next menstrual period. Generally, the first 5 days and the last 4 days of the ovulation day, together with 10 days including the ovulation day, are called the ovulation period. After the egg is discharged from the ovary, it can survive in the fallopian tube for 1-2 days to wait for fertilization; men's sperm can maintain the fertilization ability in the woman's reproductive tract for 2-3 days, so sexual intercourse is easy to become pregnant during the days before and after the egg is discharged. Because sexual intercourse is easy to conceive during ovulation, ovulation is also known as susceptible or dangerous period.
