How is the IVF feasibility test conducted?
In Vitro Fertilization (IVF) is an assisted reproductive technology. Through in vitro control, sperm and eggs are combined in the laboratory, and then fertilized eggs are transplanted into the uterus to promote pregnancy and pregnancy. In order to ensure the feasibility and success rate of IVF, medical experts will conduct a series of feasibility tests. This article will elaborate the specific contents of IVF feasibility test from four aspects: embryo quality assessment, hormone level inspection, endometrial thickness measurement and genetic testing.
1、 Embryo quality assessment
Embryo quality assessment is an important part of IVF feasibility testing. Doctors evaluate the quality of embryos by observing the appearance of fertilized eggs, cell division and embryo morphology. High quality embryos have uniform morphology and cell division, and have greater development potential. Doctors can combine optical microscope and monitoring technology to dynamically observe and evaluate the fertilized eggs. Through these assessments, doctors can select the best quality embryos for transplantation to improve the success rate of IVF.
In addition, embryo quality assessment can also help doctors judge whether there are embryo chromosome abnormalities, genetic diseases and other problems. If it is found that the embryo quality is low, the chromosome is abnormal or carries a serious risk of genetic disease, the doctor may recommend abandoning the transfer or choosing other suitable solutions.
2、 Hormone level test
Hormone level test is another important part of IVF feasibility test. During IVF, women need to receive a series of hormone injections to promote the development of multiple follicles. During this process, doctors will regularly detect the hormone levels in women, including estrogen, progesterone, luteinizing hormone, etc.
By checking hormone levels, doctors can understand the development of follicles and evaluate whether ovarian function and hormone levels are suitable for IVF. If the hormone level is abnormal or abnormal, the doctor may need to adjust the hormone treatment program or delay the IVF to improve the success rate.
3、 Measurement of endometrial thickness
The measurement of endometrial thickness is an important index in the feasibility test of IVF. The thickness of endometrium is closely related to the successful implantation of fertilized eggs and the development of pregnancy. Doctors usually measure the thickness of the endometrium by ultrasonic examination.
If the thickness of the endometrium is not up to the standard, the doctor may take some measures to increase its thickness according to individual conditions, such as increasing the hormone dose or prolonging the hormone treatment time. The possibility of successful implantation of fertilized eggs can be improved by correctly adjusting the thickness of endometrium.
4、 Genetic testing
Test tube baby technology solves the risk of some genetic diseases for couples. In the IVF feasibility test, doctors usually conduct genetic tests on both spouses to assess whether they are at risk of carrying genetic diseases.
Through genetic testing, couples can know whether there are chromosomal abnormalities, genetic mutations and other problems, so as to select suitable embryos for transplantation and reduce the risk of transmission of genetic diseases. In some special cases, doctors may also detect chromosomal abnormalities in embryos or carry out single gene detection of genetic diseases to maximize the health of IVF.
Summary
The feasibility test of IVF is one of the key steps to ensure the success of IVF technology. Through embryo quality assessment, hormone level inspection, endometrial thickness measurement, genetic testing and other tests, doctors can comprehensively evaluate the feasibility of IVF, select the most suitable embryos for transplantation, and maximize the success rate of IVF.
