What are the requirements of the third generation IVF?
With the continuous development of science and technology, three generation IVF has become a common assisted reproductive technology. Through in vitro fertilization and embryo transfer, it helps couples who cannot conceive naturally realize their dreams of fertility. However, if you want to be a third generation IVF, there are many requirements to be met. The following will elaborate on the requirements of three generations of IVF from four aspects: heredity, age, physical health and mental health.
Genetic requirements
1. No hereditary diseases: The parents of the third generation of test tube babies should carry out gene testing to ensure that there are no genetic defects carrying hereditary diseases. These diseases include steroid 21 hydroxylase deficiency, cystic fibrosis, hereditary retinopathy, etc.
2. Susceptibility assessment of genetic diseases: In addition to removing known genetic disease gene defects, it is also necessary to assess whether couples carry susceptibility genes of other genetic diseases. This can predict possible genetic risks and avoid passing on potential diseases to the next generation.
3. Genetic status of germ cells: among the three generations of IVF, embryos are obtained through in vitro fertilization. Therefore, it is very important to ensure that the germ cells (including sperm and eggs) are in good genetic condition. This may require genetic testing of germ cells to reduce the risk of genetic diseases.
Age requirements
1. Women's age limit: women's age has a certain impact on the success rate of three generations of IVF. Generally speaking, women should be between 35-45 years old. After this age, the quality and quantity of eggs will gradually decline, reducing the chance of pregnancy.
2. Age limit for men: Compared with women, the age of men has little influence on the success rate of three generations of IVF. However, too old men are often accompanied by a decline in sperm quality, which may have a certain impact on the fertilization process and embryonic development.
3. Age difference between couples: If the age difference between couples is too large, it may also affect the chance of pregnancy. Excessive age differences may lead to physical and psychological mismatches between the two sides, and thus affect the success rate of three generations of IVF babies.
Physical health requirements
1. Physical health: Before the third generation of IVF, the couple needs physical examination. This includes general physical examination, blood examination, endocrine examination, etc. By ensuring physical health, the success rate of IVF can be increased.
2. Appropriate BMI index: The body mass index (BMI) of the couple should be within the normal range, and too high or too low may affect the success rate of the third generation of IVF.
3. Immune function: The stability of immune function is very important for the success of IVF. Both spouses need to have an immune function test to ensure that the immune system works properly.
Mental health requirements
1. Psychological preparation: couples need to be fully prepared before carrying out three generations of IVF. The IVF process may experience a series of emotional fluctuations, such as anxiety, disappointment and tension. Therefore, couples need to have good psychological quality to reduce the impact of bad emotions on infant development.
2. Support system: The IVF process may bring some pressure and challenges. Couples need to have good family and social support systems to reduce pressure and increase confidence.
3. Emotional stability: couples need to maintain emotional stability before carrying out three generations of IVF. For couples with mental disorders or anxiety, depression and other problems, professional psychological counseling and treatment may be required.
Summary
Three generation IVF babies need to meet a series of requirements, including: genetic requirements (no genetic disease, genetic disease susceptibility assessment, genetic status of germ cells), age requirements (women's age limit, men's age limit, age difference between couples), physical health requirements (physical health, appropriate BMI index, immune function) And mental health requirements (psychological preparation, support system, emotional stability). Only by meeting these requirements can we improve the success rate of three generations of IVF and realize the couple's reproductive aspirations.
