What are the precautions after IVF transplantation?

IVF is currently the fastest and most effective way to treat infertility. Many infertile families have conceived their own babies through IVF technology. Today I will tell you about the precautions after IVF transplantation.

Precautions after IVF transplantation

1. Rest in bed

Lie still for 48 hours after IVF transfer, and try to avoid turning over or getting up. If you turn over and lie on your side, the angle must be less than 45 degrees. This depends on the condition of the fertilized egg itself. Usually, the quality of the fertilized egg determines the time for successful implantation after IVF transfer, which is generally about 3-4 days.

2. You cannot take a bath after surgery

You cannot take a bath within 48 hours after the operation. It is better to take a shower after pregnancy, not a tub bath, to avoid infection.

3. Reduce exercise

Do not engage in physical labor, move things, lift heavy objects, and avoid strenuous exercise during pregnancy.

4. Pay attention to your diet

After the operation, you can increase your nutrition appropriately, eat more lean meat, fish, eggs and other protein-rich foods, and eat more vegetables and fruits. It is not advisable to eat raw, cold, spicy and stimulating foods.

5. Keep bowel movements smooth

Eat more fiber-rich foods, such as vegetables and fruits, to avoid constipation

6. Prohibition of sexual intercourse

Sexual activity is prohibited to avoid inducing uterine contractions and affecting the implantation of the fertilized egg.

7. Keep your mood relaxed

After embryo transfer, try to keep a calm mind and provide the embryo with a quiet and relaxing environment, which will help it implant and grow.

8. Be careful not to catch a cold

Pay attention to weather changes, add or remove clothes appropriately, and try not to get sick to avoid affecting the development of the fertilized eggs.

9. Observe changes in your body

After the IVF transplant, pay attention to observe whether there are obvious abdominal pain, bleeding and other symptoms. If you find any obvious discomfort, seek medical attention in time.

Signs of successful IVF transfer

1. There is no sign of success or failure

The success or failure of the transplant is carried out secretly in the ovary and will not affect any perception of the mother, such as emotions, pain, etc. Implantation will occur 3 to 4 days after the transplant. The hospital will recommend going to the hospital for a pregnancy check about 14 days after the transplant. There should be no reaction during the whole process. Only pregnancy tests and long-term tests with test strips can determine whether you are pregnant.

2. Embryo quality is key

Embryo quality includes embryo morphology score, embryo growth rate and embryo chromosomal abnormality. Embryo morphology score is the most widely used embryo quality evaluation standard. Patients with recurrent poor embryo morphology scores can try micro-stimulation or natural cycles to reduce the dose of exogenous ovulation-inducing drugs in order to improve egg and embryo quality.

The dynamic observation microscope system can observe the embryonic development process continuously for 24 hours, so as to evaluate its growth rate and division phase and select the most normal embryo for transplantation.

3. The endometrium is also very important

When there are uterine abnormalities, such as polyps, submucosal uterine fibroids, intrauterine adhesions, endometritis and other lesions, the chance of implantation may be reduced. Hydrosalpinx contains various "poisons". If it is not treated, it will flow back into the uterine cavity, which will "wash away", "drowned" or "poison" the embryo and greatly reduce the chance of embryo implantation.

Hysteroscopy can detect and solve the causes of some patients with repeated failures and significantly improve their implantation rate. For patients with repeated failures, it is also necessary to check whether there is hydrosalpinx. If there is hydrosalpinx, it is recommended to treat the hydrosalpinx first, ligate or remove the fallopian tubes, and eliminate the impact of the hydrosalpinx on implantation. If the pelvic adhesion is severe and surgery is not possible, tubal occlusion can also be considered.

4. Immune abnormalities can also hinder implantation

Studies have shown that abnormally elevated systemic or local natural killer cell activity may be toxic to the embryo and hinder implantation. Treatment can be achieved through intravenous infusion of immunoglobulin or fat emulsion. In addition, active immune deficiency can be induced by injecting the husband's lymphocytes to induce the active immune function of the body.

Coagulation abnormalities such as antiphospholipid syndrome and thrombophilia can lead to thrombosis in small placental blood vessels, resulting in insufficient blood supply to the endometrium, a decreased chance of embryo implantation, or an increased risk of miscarriage.

IVF success rate

1. Success rate

The birth of IVF technology has made the topic of success rate a hot topic among patients. From 1978 to 2015, it has been more than 30 years. With the continuous improvement of medical conditions and the increasing clinical experience, the success rate of IVF has gradually increased, from the initial 20%-25% success rate to the current level of more than 40% or even higher, which is undoubtedly an affirmation of medical technology. However, the success rate of IVF is not the same for everyone. Due to the inconsistent degree of disease, age, medical conditions and doctor's skills, the success rate is also different.

2. Age affects success rate

Age is an important factor that determines the success rate of IVF. With the increase of age, the ovarian function gradually declines, and this sign of aging is irreversible. The eggs will naturally not be spared when the ovarian function declines, which will lead to a decline in egg quality. Generally speaking, the success rate of IVF in the age group of 21-30 years old is about 60%; the success rate of IVF in the age group of 30-35 years old is about 45%-50%; over 35 years old, the ovarian reserve function declines, the quality of oocytes changes, and the quality of eggs begins to age, which makes it impossible to transfer embryos, and the success rate of IVF is only about 40%-45%; the success rate is only about 30% or even lower for those over 40 years old.

3. Semen affects the success rate

Fertility is a matter for two people. The number and motility of male sperms intuitively depend on the fertilization of the egg. If the number of sperms per cc of semen is less than 10 million or the motility is less than 30%, in vitro fertilization will be recommended and artificial insemination is not suitable; if it is less than 5 million per cc or the motility is less than 20%, in vitro fertilization is recommended instead of a "gift baby"; if it is less than 1 million per cc or the motility is less than 10%, ICSI (intracytoplasmic sperm injection) in vitro fertilization is required.
