Many people may not be aware that infertility tests have special time restrictions; if the test is conducted at the wrong time, it will not only fail to be accurately interpreted, but also increase some unnecessary risks. Common infertility tests include the following items 1. ovarian function test: the second and third day of menstruation Generally, blood is drawn on the second or third day of menstruation to check sex hormones, because at this time, sex hormones in women’s bodies do not fluctuate much, so the functional status of the ovaries can be clearly determined. 2.Lactation hormone check: morning is better Generally, if women’s lactation hormone is too high, it will interfere with normal ovulation and menstrual cycle. Since lactation hormone will rise physiologically in the evening, especially at night, it is recommended to check in the morning, which is more accurate. 3.Ovarian tumor index test: Non-menstrual period is more suitable. If the ovarian tumor index (Ca125) is taken during menstruation, most of them will show a high false positive, which will make patients worry and think they have an incurable disease. Fallopian tube imaging: 3-7 days after menstruation Fallopian tube imaging is the most common test to assess the patency of the fallopian tubes in women by administering contrast to the uterine cavity and fallopian tubes. 5.Hysteroscopy and laparoscopy: three to seven days after menstruation is the most suitable Hysteroscopy requires irrigation to open the uterine cavity for examination, while laparoscopy involves the injection of melanin into the uterine cavity and fallopian tubes to read whether the fallopian tubes are blocked. 6. Male sperm test: abstinence for 2 to 2 days Male sperm test generally requires only a short abstinence for 2 to 4 days, with the staff of the Center for Reproductive Medicine working hours, placing the collected semen in the examination box, and trying to deliver it to the technician within an hour, and the results will be known within half an hour. It is generally recommended that patients who are first diagnosed with infertility come to the clinic within 2 days of seeing red menstruation, and all the tests can be completed within a month, and with the treatment of the physician, it is not as difficult as you think to get pregnant successfully!
