embryo transplantation

The success rate of embryo transfer and IVF transfer did not reach 100%. Now, even if IVF transplantation has developed to the third generation, no one dares to say that it is a very mature technology. Let's look at embryo transfer.

Embryo transfer 1 embryo transfer is the key step of pregnancy, which is to transfer the embryos formed after in vitro fertilization into the uterine cavity. Embryo transfer is divided into fresh embryo transfer and frozen-thawed embryo transfer according to whether it has been frozen or not. According to the days of embryo development in vitro, it is divided into embryo transfer on the third day and blastocyst transfer on the fifth day. Some patients may undergo complicated schemes such as step-by-step transplantation, and the scheme must be decided by the doctor according to his personal situation.

Before transplantation, patients need to hold their urine properly to make their bladder full, which is beneficial for doctors to observe the size, position and shape of uterus through transabdominal B-ultrasound and quickly judge the direction of transplantation tube and the position of embryo. Then, with the help of embryologists and nurses, the embryos were transplanted into the uterine cavity using a fine transplantation cannula. Because the transplantation tube runs along the natural channels of vagina, cervix and uterine cavity, the operation can be successfully completed within 2-4 minutes, and there are no abnormalities such as severe reproductive tract malformation and myoma compression. The risk factor of the operation itself is low, and some patients have no feeling. For patients who have difficulty in inserting the graft cannula, it is necessary to use the hard core of the graft to help the transplantation.

Embryo transfer is a common method of in vitro fertilization, also known as fertilized egg transfer. The specific method of embryo transfer is to implant the embryos fertilized in vitro and developed at an early stage into the uterus of women, and then further develop into new individuals. Embryo transfer can greatly improve the pregnancy rate of women, and it is an effective treatment for infertility, which has been widely used in the medical field.

Embryo transfer 2 Embryo transfer refers to the transfer of embryos that have been cultured in the laboratory into the uterus of patients through transfer tubes, which generally includes fresh embryo transfer and frozen embryo transfer.

1. If the patient does not have high estrogen, high progesterone or thin intima, transplantation is not recommended. Embryos cultured for 3-5 days, that is, fresh embryos can be transplanted, usually on the third or fifth day after transplantation. 2. When taking eggs in the fresh cycle, all embryos may be frozen for some reasons, such as taking too many eggs from the ovary or the patient is not suitable for transplantation in the fresh cycle. After 2-3 months of ovarian rest,

Patients can have frozen embryo transfer, and frozen embryo transfer can do natural cycle and artificial cycle. Embryo transfer generally recommends two embryos for patients under 35 years old, and three embryos for patients over 35 years old on the third day. However, with the increase of complications of multiple pregnancy, the reproductive community is increasingly inclined to single embryo transfer or single blastocyst transfer.

After embryo transfer, you must pay attention to rest. The first three days should be mainly bed rest, and you can walk slowly indoors. You can exercise properly in the future, don't do strenuous exercise, pay attention to work and rest on time at night, and don't stay up late. Pay attention to reasonable diet, balanced nutrition, proper consumption of high-quality protein food and folic acid supplementation can promote the development of embryonic nervous system and prevent neural tube malformation. Be careful not to share a room,

Sexual life is forbidden in the first three months after embryo transfer, because the placenta has not yet formed during this period, and the embryo development is unstable, which is easy to cause abortion. After embryo transfer, you must take relevant drugs according to the doctor's advice to maintain the hormone level in the body. Don't use other drugs indiscriminately, try to avoid virus infection and ionizing radiation, and don't watch your mobile phone or computer for a long time.

What are the precautions after IVF embryo transfer?

Matters needing attention after IVF embryo transfer mainly include diet and daily life:

1. Don't have sex, avoid intimate behavior with your husband, and put an end to any behavior that may cause uterine contraction.

2. Rest: 48 hours after transplantation, try to lie flat and try to stay flat. Don't turn over in bed, and don't work hard. When you get up, support yourself sideways and get up again. After 48 hours, you can lie in bed (the angle is less than 45 degrees) and watch less TV, or watch less TV and surf the Internet. You can kill time by reading some books.

Be careful not to become an emotional book. Try to rest as much as possible in the future. After 3 days, you can do a small amount of small-scale activities in the house for 5 days. After 5 days, you can engage in small-scale outdoor activities, especially when you are not tired from work. It is best to stay away from work before pregnancy. Keep a regular routine, don't stay up late and get enough sleep. It is best to have an injection at home in the first 5 days.

3. Exercise: Avoid strenuous exercise after transplantation: don't stretch hard, don't pinch your fingers, don't lift the master, don't squat down, don't lift heavy objects, don't walk fast, don't jog, don't ride a bike, and walk slowly.

4. Diet: Eat whatever you want, especially vegetables and foods rich in protein. It is recommended to eat a grapefruit every day.

Things that are not recommended: wine, cigarettes, coffee, tea, sesame oil, bananas, papaya, crabs, corn, and coix seed are not good for embryos.

5. Stay healthy: don't get sick, pay attention to the weather changes, and increase or decrease clothes appropriately.

6. Mood: You can't do this by keeping a happy mood. At least, you should keep your mood calm and relaxed, and don't think too much about the result.

7. Socialization: Try not to participate in social activities to avoid crowded environment and serious air pollution. Avoid being frightened by others or traffic.

8. Shit: Don't have loose bowels or constipation. Especially constipation, be sure to keep the stool unobstructed. If you have constipation? F is like shit that doesn't need hardware decoding, wait until it's convenient. Generally speaking, eating more vegetables can keep the stool unobstructed. Introduce several suitable methods to keep defecation unobstructed:

(1) Eat Yangtze beans once a day, which can be fried or cooked and then cooled.

(2) Eating beans is very useful for some people to keep their stools unobstructed.

(3) Eat milk and honey.

(4) A glass of water in the morning and a glass of water in the evening is not sloppy for some people with constipation.

(5) Do not eat spicy food, and do not use drugs to relieve constipation.

9. Bathing: No bathing for 48 hours after transplantation. Bathing and shampooing can be done every other day or at a longer interval, but water is necessary.

10. In case of abnormal abdominal pain, abdominal distension and vaginal bleeding, you should contact a doctor in time.

Embryo transfer 3 What should I pay attention to in embryo transfer?

Embryo transfer, also known as fertilized egg transfer, commonly known as abdominal pregnancy, refers to the technology of transplanting the early embryos of female animals or embryos obtained by in vitro fertilization into other female animals of the same species with the same physiological state, so that they can continue to develop into new individuals.

IVF is a popular technology to treat infertility in the world. It allows infertile couples to have their own children smoothly, so it is favored by many people. However, there are still some precautions before and after embryo transfer surgery, which women must pay attention to.

1, before transplantation

Before embryo transfer, you need to be mentally prepared and not nervous. Waiting outside the operating room in the early morning of the transplant day, the doctor will give the transplanted patient a B-ultrasound, and if there is no abnormality, he will find a nurse to inject progesterone, drink water at the door of the operating room and hold his urine, waiting for the transplant.

2. After transplantation

Pay attention to diet, hygiene and medication after embryo transfer. You can't hold your urine. Bed rest is based on the principle of comfort, and there is no limit to bed rest time. After transplantation, continue to take folic acid and vitamin E, and inject progesterone according to the injection certificate until the blood HCG is checked and other special drugs are prescribed by the doctor. Pay attention to food hygiene and avoid irritating and nourishing foods (such as black-bone chicken soup, turtle soup, hot pot, brown sugar water, etc.). ).

Through the introduction of the article, I believe many people have a certain understanding of the matters that should be paid attention to in embryo transfer surgery. This technique is to borrow abdomen. So far, this technology is very safe. Pay more attention to the key points, and the probability of success will be higher.
