The 3 to 4 days before and after ovulation is the easiest time to get pregnant, and for healthy couples, intercourse during this period is more likely to result in conception. For women with regular menstrual cycles, ovulation usually occurs about 14 days before the next menstrual period. Sperm can usually survive for 1 to 3 days after entering the female reproductive tract, and fertilization occurs within a few hours after ovulation, so the 3 to 4 days before and after ovulation are the most likely time to get pregnant. For couples who are physically healthy, intercourse around the time of ovulation can help to conceive a child, but there are still many unexplained causes of infertility in the clinic, and intercourse during this period does not guarantee conception. If you are not using contraception, have a normal sex life, and have been living with your spouse for one year and still have not conceived, it is recommended that you go to the hospital as soon as possible for examination and treatment.
