Test tube baby taboo: dietary requirements before embryo transfer
IVF is to fertilize and develop embryos in vitro through artificial assisted reproduction technology, and then transfer the embryos to the mother's uterus to complete pregnancy. In order to improve the survival rate of embryos and the success rate of pregnancy, there are a series of dietary requirements and taboos before IVF transplantation. Next, we will elaborate from four aspects: dietary structure, nutritional requirements, diet and supplementary nutrition.
1、 Dietary structure
The diet structure of IVF infants before transplantation needs to be reasonably matched with various foods to ensure adequate nutrition and energy. In daily diet, the intake of protein, carbohydrate and fat should be guaranteed, and the intake of fresh vegetables, fruits, whole grains and low-fat dairy products should be increased. Proper supplementation of vitamins and minerals, such as vitamin C, vitamin E, folic acid, iron, calcium, etc., will help improve the quality of embryos.
In addition, it is recommended to limit the intake of salt and sugar in the diet. High salt diet will increase blood pressure, which is harmful to embryonic development. Excessive sugar intake may lead to blood sugar fluctuations, affecting ovarian function and hormone balance.
2、 Nutritional requirements
Test tube babies need to have good nutritional status before transplantation to promote the development of embryos and integration into the mother. Among them, protein is a very important nutritional component, which is the basic component of embryonic cells. Choose foods rich in high-quality protein in your diet, such as chicken, fish, eggs and beans.
In addition, the intake of vitamin B group, vitamin D and minerals should also be increased in the diet of test tube infants. Vitamin B group is involved in the division and development of embryonic cells. Vitamin D helps to absorb calcium, and minerals such as iron, calcium and magnesium are also necessary for embryonic development.
3、 Avoid food
Some foods should be avoided before IVF transplantation to avoid adverse effects on embryos and pregnancy. First, drinks with high levels of alcohol and caffeine should be banned. Both alcohol and caffeine have teratogenic risks, which may lead to abnormal embryonic development.
Secondly, raw and cold food and sashimi should be avoided to avoid bacterial infection. Raw food is easily contaminated by various pathogens, posing a threat to embryonic health. In addition, it is not recommended to eat too much fried food and high sugar food to avoid weight gain and blood sugar fluctuation.
4、 Supplemental nutrition
Before IVF transplantation, it is sometimes necessary to supplement nutrients properly under the guidance of doctors. For example, people with malnutrition or vitamin deficiency can be supplemented with corresponding nutrients. In addition, in some special cases, such as older women or patients with potential diseases, IVF may need further examination and evaluation to determine whether special diet or drug intervention is required.
To sum up, IVF diet should be adjusted and guided reasonably according to dietary structure, nutritional requirements, diet and supplementary nutrition before embryo transfer. Reasonable diet and nutrition intake play an important role in embryonic development and pregnancy success. Therefore, in the process of IVF, patients should closely cooperate with doctors' suggestions and reasonably arrange diet to improve the survival rate of embryos and pregnancy success rate after transplantation.
