How can patients who need IVF pregnancy assistance schedule their visits and reduce the number of visits? Taking the long luteal phase protocol as an example, one cycle of IVF assisted conception treatment (from the start of the test to knowing if the pregnancy is successful) usually takes 2 months if it is scheduled properly. First visit: day 2-4 of your period, you need to arrive before 9:00 on an empty stomach. Counting starts on the 1st day of seeing blood. The main assessment of ovarian function (checking sex hormones and ultrasound to measure the number of sinus follicles) and completion of some of the tests requested before the procedure. Second visit: 3-7 days after menstruation, abstinence from sexual intercourse is required. The main assessment will be the endometrial condition (hysteroscopy), follicular growth and completion of the outstanding preoperative tests. Third visit: one week after ovulation, need to arrive before nine o’clock. Blood will be collected for estradiol and progesterone, and the mid-luteal phase will be determined before starting the descending regulation into the treatment cycle. The fourth visit: 14-16 days after down regulation, you need to come to the hospital before nine o’clock. After blood collection and ultrasound to confirm that the standard of down regulation is achieved, controlled ovulation promotion will be initiated. You will need to visit the hospital frequently for about 10-14 days after the initiation of controlled ovulation to monitor the growth of the follicles. When the follicles have reached the maturity standard, you will be ready for the night injection and egg retrieval. You will need to fast on the day of egg retrieval, and the order of egg retrieval will be arranged according to the order of the night shot. You can go home and rest after the egg retrieval. You can come to the hospital 14 days after the egg retrieval for a blood test for pregnancy.
