What is the impact of IVF test items on the success rate?
IVF is an assisted reproductive technology, which helps couples who cannot conceive naturally realize their reproductive dreams through in vitro fertilization. The success rate of IVF is affected by many factors, among which the examination item is the most important one. This article will discuss the influence of IVF test items on the success rate from four aspects: embryo quality, uterine environment, hormone level and genetic testing.
1. Embryo quality
Embryo quality is one of the key factors in the success rate of IVF. During in vitro fertilization, doctors will take eggs from the woman and combine them with male sperm to form a fertilized egg. The quality of the fertilized egg can be checked by evaluating its shape, cell division speed and chromosome number. If the quality of the fertilized egg is high, that is, the shape is good, the cell division is normal, and the number of chromosomes is normal, then the success rate after transplantation will be greatly improved.
In some authoritative medical institutions such as Peking Union Medical College Hospital, the evaluation of embryo quality is carried out through microscopic observation and chromosome detection. When abnormal fertilized eggs are found in the assessment process, the doctor may suggest giving up transplantation to reduce the risk of unhealthy babies for the patient.
2. Uterine environment
The uterine environment is also important for the success rate of IVF. The thickness, shape and relaxation of endometrium will directly affect the implantation of fertilized eggs and the growth and development of embryos. Therefore, before IVF, the doctor will conduct a detailed examination of the woman's uterus.
For example, Renji Hospital affiliated to Shanghai Jiaotong University School of Medicine is affiliated to the Infertility Diagnosis and Treatment Center. They will use ultrasound and hysteroscopy to observe the condition of endometrium. If endometrial abnormalities are found, doctors may recommend appropriate treatment or intervention measures to improve the success rate of IVF.
3. Hormone level
Hormone level is also one of the important factors affecting the success rate of IVF. The change of female hormone level will directly affect the function of ovary and the development of follicle, thus affecting the quality and quantity of eggs.
In some well-known research institutions, such as the Shanghai Institute of Life Sciences of the Chinese Academy of Sciences, doctors will assess female hormone levels through blood tests. If the hormone level is found to be abnormal, doctors may formulate corresponding adjustment plans, such as using synthetic hormones, accurately calculating the dosage, etc., to improve the success rate of IVF.
4. Genetic testing
Genetic testing is another key link in the process of IVF. There may be hidden dangers of some genetic diseases between couples, which may lead to abnormal fetal development or birth defects. To reduce this risk, doctors usually carry out genetic testing on the fertilized eggs.
In some professional medical institutions, such as Guangzhou Maternal and Child Health Care Hospital, genetic testing is carried out through pre implantation embryo genetic diagnosis technology. If the test results show that an embryo has a high-risk genetic disease, the doctor will recommend abandoning the embryo to improve the success rate of IVF.
To sum up, the IVF test items have a significant impact on its success rate. Embryo quality, uterine environment, hormone level and genetic testing are important factors affecting the success rate. Through strict evaluation and appropriate adjustment by professional doctors, the success rate of IVF can be improved and more couples can realize their dream of becoming parents.
