What does IVF mean? Who is suitable for IVF?

Couples who cannot conceive normally under natural conditions can choose to do IVF to achieve the goal of pregnancy. Many people still don’t know what IVF is. Next, the editor will take you to learn about IVF.

What does IVF mean?

"Test-tube babies" are not babies that really grow up in test tubes. Instead, several eggs are taken from the ovaries and combined with the man's sperm in the laboratory to form embryos, which are then transferred to the uterus to implant in the mother's uterus and become pregnant. Normal conception requires sperm and eggs to meet in the fallopian tube, combine to form a fertilized egg, and then the fertilized egg returns to the uterine cavity to continue the pregnancy. Therefore, "test-tube babies" can be simply understood as laboratory test tubes replacing the function of fallopian tubes and are called "test-tube babies".

Although IVF was originally used to treat infertility caused by blocked fallopian tubes, it has now been found to be helpful for infertility caused by endometriosis, sperm abnormalities (abnormal number or abnormal shape), and even unexplained infertility. Studies have shown that the pregnancy rate after one cycle of treatment is around 40%, and the birth rate is slightly lower.

How many days can the test tube transplant be detected?

For those infertile women, IVF technology is a hope for them, so the success of IVF is very important. How many days after IVF can the test be detected? Generally, if it is successful, it will take about 14 days, and the 14-day check is the best.

This depends on the fertilized egg itself. Usually, the quality of the fertilized egg determines the time of successful implantation after transplantation. Some implantation takes about 3-4 days, while others take longer. Individual differences determine the time, which requires test tube parents to be fully prepared for pregnancy in advance. Take more nutritional supplements and adjust your mentality.

The key factors that affect IVF implantation are usually the quality of the embryo and the endometrium of the woman. If the endometrium is too thick and causes hyperplasia and inflammation, the adverse environment will have a great impact on conception. This requires women to do a full physical examination during pregnancy and treat all inflammation.

In vitro fertilization, the embryo on the third day of development is transplanted into the female uterus. 3 to 5 days after the transplant, the embryo invades the endometrium and implants, and its trophoblast cells secrete hCG. Generally, hCG is tested in the blood 14 days after the transplant to determine whether the pregnancy is present. If it is elevated, a vaginal B-ultrasound is performed 28 to 30 days after the transplant. Only when the gestational sac and embryo heartbeat are seen under ultrasound can clinical pregnancy be diagnosed. Only live births of healthy newborns can be considered a final success. The IVF pregnancy success rate is 40%.

Precautions after IVF transplantation

What precautions should be taken after IVF transplantation to help improve IVF embryo implantation?

1. Diet. You can eat whatever you want, especially vegetables and protein-rich foods. It is recommended to eat a grapefruit every day.

Foods that are not recommended: alcohol, cigarettes, coffee, tea, sesame oil, bananas, papayas, crabs, corn, and coix seeds, as these are not good for the embryo.

2. Lie down as much as possible in the 48 hours after the transplant. Do not turn over or get up vigorously in bed. When getting up, first turn sideways and support your body with your hands before getting up. After 48 hours, you can lean on the bed (angle less than 45 degrees), watch less TV, or do not watch TV, and spend less time on the Internet. Maintain a regular work and rest schedule, do not stay up late, and get enough sleep.

3. Take a bath. Don’t take a bath for 48 hours.

Who is suitable for IVF?

1. Women should be under 30 years old (the younger the woman, the easier it is to succeed).

2. Secondary infertility (history of pregnancy), especially ectopic pregnancy, indicates that the embryo has good survival ability.

3. The in vitro culture of embryos is ideal and there are multiple high-quality embryos available for transplantation.

4. If the uterus is normal and the embryo transplant is successful (it is easy to insert the transplant tube into the uterine cavity).
