Under normal circumstances, how long it takes to conceive needs to be analyzed and judged according to the physical condition of the couple. If the couple has a normal sex life and does not use contraception, they can usually conceive within 1 year of pregnancy preparation. If the couple has not conceived for more than 1 year, they need to go to the hospital to check the cause of infertility and then intervene or regulate according to the specific cause. After sexual intercourse, normal sperm can usually survive in a woman’s body for 2-3 days and have the ability to fertilize. At this time, if a woman is ovulating, fertilization is usually possible within 12-24 hours after ovulation, but it usually takes 7-10 days for the egg and sperm to reach the uterine cavity and successfully implant, although the exact time varies from person to person. Therefore, couples who are normally preparing for pregnancy can use early pregnancy test 7-10 days after intercourse to test for conception and are usually able to conceive within 1 year. If you have been preparing for pregnancy for more than one year, you need to check the cause of infertility to find out whether it is a blockage of the fallopian tubes in women or a decrease in the quality of semen in men. In addition, infertility may also be caused by endocrine disorders or ovulation abnormalities caused by excessive, stressful and anxious psychological factors, so it is necessary to relax and avoid excessive psychological stress when preparing for pregnancy. It is important to note that both men and women should undergo preconception checkups before preparing for pregnancy to rule out the causes of infertility. During the preparation period, you can predict the ovulation date of a woman and have intercourse 2-3 days before or 24 hours after ovulation to increase the chance of pregnancy. During the preparation period, both men and women need to make physical adjustments and take appropriate physical exercises to promote conception. It is also necessary to quit smoking and alcohol, reduce the time of exposure to electronic products, stay away from radioactive products, and avoid staying up late to ensure sufficient sleep in order to improve the conception rate.
