Due to the high level of medical care in the United States, more and more people are going to the United States to have in vitro fertilization, but after all, there will still be some inconvenience when going to other places. In order to reduce or avoid the inconvenience of seeking medical treatment in the United States, it is necessary to have some understanding of the current situation of test tubes in the United States. So is the success rate of in vitro fertilization high in the United States in 2022? What is the effect of going to the United States to make a test tube?

1、 Domestic preparation materials

Perform relevant tests to let the doctor know your ovarian function. The specific tests are as follows:

1. Six sex hormones: follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), progesterone (P), testosterone (T), and prolactin (PRL).

2. Uterine examination: Go to the hospital for a vaginal ultrasound on the second or third day of menstruation, check for fibroids and polyps in the uterus, and check for the number of basal follicles.

3. Infectious disease inspection: hepatitis B, hepatitis C, AIDS, syphilis, gonorrhea, mycoplasma, chlamydia, etc.

2、 Video consultation with doctors

Usually, the doctor assistant will reply to preliminary inquiries from domestic customers on WeChat, and can basically answer all their questions, including surrounding issues such as accommodation, transportation, and in vitro fertilization. If there are complex medical issues or customers are more confident about the doctor's video consultation, they can also arrange WeChat video consultation.

3、 Domestic recuperation

Patients need to adjust their bodies to their best condition before going to the United States. They can consume more high protein foods, such as beef and mutton, fish and shrimp, protein powder, etc. Or eat more estrogen foods that promote endometrial growth, such as black beans, soybeans, soybean milk and other soy products.

4、 Entering the test tube cycle in the United States

There are two ways to come to the United States because it is necessary to cooperate with the patient's menstrual cycle to enter the ovulation induction cycle:

If the patient has ample time, it is easier to control their own time. He can arrive a few days before his period, go to the United States to wait for his period, and then go to the clinic for examination the day after his period. On the third day, he will start receiving injections to promote ovulation, and after 36 hours of ovulation, he will collect the eggs. If the conditions for fresh embryo transfer are not met, the egg can be retrieved and rested for 2 days before returning to China. Embryos need to stay for approximately 21 days after freezing. Those who meet the conditions for fresh embryo transfer shall be transferred on the third or sixth day, and pregnancy shall be confirmed by blood test 12 days after transfer. Guests can wait for the results in the United States or rest for 2-3 days after transplantation to return home to confirm pregnancy.

5、 Cultivating embryos

There are currently two methods for cultivating embryos, one is to preserve them on the third day and the other is to preserve them on the fifth day. If you need to choose a gender, you can only raise the embryo until the fifth day for PGS (chromosome screening) to exclude chromosomal abnormalities in the embryo, and at the same time, you can know the gender of the embryo. If it is an elderly patient, the probability of egg chromosomal abnormalities is high. Usually, doctors also suggest that embryos should be preserved until the fifth day of PGS.

6、 Embryos screened by PGS

Whether an embryo must undergo PGS screening is not a necessary procedure, but a patient's own choice. If you need to choose a gender, you have no choice but to raise the embryo until the fifth day for PGS; The probability of chromosomal abnormalities in elderly patients is high, and PGS is also needed to ensure the health of the embryo. If you want to do PGS, you can only cultivate embryos until the fifth day. Due to current technological limitations, only half of the embryos will last for three to five days before being screened by PGS. Usually, the other half is eliminated. If you are unlucky, you may be completely wiped out without leaving a healthy embryo.

7、 Embryo transfer

The doctor will confirm whether it is a fresh embryo transfer or a frozen embryo transfer based on the patient's actual situation. Fresh embryo transfer: If a patient needs fresh embryo transfer, several conditions must be met, including the uterus and hormone levels, especially after receiving an ovulation promoting injection, the hormone levels in the body will change. Doctors can only perform fresh embryo transfer if there are no problems. Frozen embryo transfer: If the patient is not suitable for fresh embryo transfer, the embryo will be frozen. Frozen embryos have three days, and frozen embryos have five days. The customer needs to undergo frozen embryo transfer in the United States later. Before frozen embryo transfer, it takes 21 days to take medication to thicken the endometrium, so the patient needs to stay in the United States for 21 days. If you want to shorten your stay time, you can bring the transplanted medicine back home when you first come to retrieve the eggs, which can shorten your stay time in the United States.

Pregnancy was confirmed by a blood test 12 days after transplantation. After successful transplantation, the doctor instructed the patient to take medication for at least one month to assist in embryo implantation and follow up until 12 weeks. Only after confirming that the fetus is normal can the task be completed. This is the process of in vitro fertilization in the United States, which is very professional and has a very high success rate. I hope it can effectively help everyone.
