How many tests does IVF need?
In vitro fertilization (IVF) refers to the process of culturing the fertilized eggs to the appropriate stage of development through in vitro fertilization (IVF) technology, and then implanting them into the mother's uterus to achieve pregnancy and delivery. The success rate of this medical technology is closely related to the treatment effect. In order to improve the success rate, IVF needs to go through many tests to ensure the quality and health of embryos. The following details how many tests are needed for IVF from four aspects: embryo quality screening, implantation preparation, pregnancy monitoring and genetic disease screening.
1. Embryo quality screening
The screening of embryo quality is one of the key factors for the success rate of IVF. During the culture process, doctors will evaluate the well developed embryos and select the most promising embryos for implantation. Normally, the hospital will evaluate and select when the embryo is cultured for 3-5 days. If multiple healthy embryos are available, doctors can decide to implant a single embryo into the mother to reduce the risk of multiple pregnancies.
Through embryo quality screening, the success rate of IVF has been improved. Generally speaking, the success rate of the first attempt is about 30-40%, but as the experiment goes on, the success rate will gradually increase. Therefore, embryo quality screening is an important test in IVF.
2. Implantation preparation
After the embryo quality screening is completed, the doctor will determine the best implantation time according to the women's menstrual cycle. In the implantation preparation stage, women need to undergo endometrial preparation to create an environment suitable for embryo implantation. To ensure the normal growth and preparation of the endometrium, women may need to have multiple progesterone tests or blood tests.
The test in the implantation preparation stage aims to ensure that the embryo can be implanted and continue to develop normally. Doctors will adjust the implantation plan according to the actual situation of women to improve the success rate of IVF.
3. Pregnancy monitoring
Once the embryo is successfully implanted, the woman enters pregnancy. During IVF pregnancy, doctors regularly check and monitor pregnant women to ensure the normal development of embryos and the physical condition of the mother. These tests may include ultrasound, blood tests, and physical examinations. The purpose of pregnancy monitoring is to discover and deal with any potential problems or complications in time and ensure the healthy growth of embryos.
Pregnancy monitoring is an important part of IVF. It can not only improve the safety of pregnant women and embryos, but also timely intervene and treat possible complications to ensure that IVF can obtain the best development environment.
4. Genetic disease screening
Another important test of IVF is genetic disease screening. In the process of embryo culture, doctors can screen embryos for genetic diseases through cell sampling. These genetic diseases may include chromosome abnormalities, single gene genetic diseases and other genetic diseases.
Genetic disease screening can eliminate embryos carrying genetic diseases, reduce the risk of birth defects, and improve the health rate of IVF. This test is particularly important for patients with a family history of hereditary diseases.
Summary
For the successful implementation of IVF, embryo quality screening, implantation preparation, pregnancy monitoring and genetic disease screening are crucial links. Through many tests, doctors can select the most suitable healthy embryos for implantation, ensure that women's endometrium is fully prepared, monitor and deal with problems during pregnancy, and exclude embryos carrying genetic diseases, so as to improve the success rate and health rate of IVF.
Therefore, test tube babies need to go through many trials to ensure successful pregnancy and the realization of healthy pregnancy.
