According to the relevant research: a 24-year-old woman, the pregnancy rate of one month of normal sexual life after marriage is 25%, 5 months is 40%, 8 months is 75%, while more than 90% of the year after marriage can be pregnant, the first pregnancy rate of two years after marriage is 94.6%. However, in the third year, its first pregnancy rate rises only by 1.9%. Therefore, the diagnosis of infertility in China is based on the fact that a year of normal sexual life after marriage without any contraceptive measures and no pregnancy should be noticed and the cause of infertility should be examined in hospital in time. The causes of infertility are complex and a series of tests must be done to make a clear diagnosis. Moreover, these tests need to be done at a certain time, and sometimes they have to be done together with the couple. Therefore, the first time an infertile person comes to the hospital for examination should be 3 to 7 days after her menstrual period is cleared, and it is better to ask her husband to come with her for semen testing. It is worth noting that semen testing requires 5-7 days of abstinence, so couples should not have intercourse for 5-7 days before coming for the test. When having a fertility test, you should strictly follow the doctor’s appointment and keep in mind your menstrual cycle. Because these tests are related to the menstrual cycle, such as blood sampling for sex hormones should be done on the 3rd day of menstruation, tubal lavage or imaging should be done 3 to 7 days after menstruation, ovulation monitoring on the 8th to 10th day of menstruation, and diagnostic scraping 3 days before or within 6 hours after menstruation. Failure to observe the time of the test can make the diagnosis difficult due to its inaccurate results. The diagnosis and treatment of the cause of infertility is a very tedious process, and it is not a problem that can be solved by a single prescription or a test prescription. Therefore, patients should not seek treatment from charlatans to avoid delaying the good opportunity for treatment. The right way is to choose a regular hospital for systematic examination and then comprehensive treatment according to the cause of the disease. With the development of assisted reproduction technology, the success rate of infertility treatment is getting higher and higher, therefore, patients do not need to worry too much.
