The methods to increase the chance of conception are: 1. Choose a good time for intercourse, monitor the time of ovulation through ultrasound or ovulation test strips, and arrange intercourse on the day of ovulation and two days before and after the day of ovulation, which can increase the chance of conception. 2. The key period for the fertilization of the egg is the 7th-10th day after intercourse, so don’t smoke or drink alcohol during this period, don’t take drugs at will, and try not to catch a cold or overexert yourself, which will also help to improve the chances of conception. 4. Both men and women who are preparing for pregnancy should do a good health check and pre-conception preparation, and if they are suffering from basic diseases that affect the ability to conceive, they should first actively treat the original disease.
