Contraindications of three generations of IVF in Shanghai
IVF technology is an assisted reproductive technology, which provides a choice for couples who cannot conceive naturally. However, not all couples are suitable for third-generation IVF technology. The following are the contraindications of third-generation IVF generally recognized by some hospitals in Shanghai:
1. Age limit
Age is a limiting factor that three generations of IVF babies may face. Generally speaking, if a woman is over 35 years old, the quality of her eggs will decline, which may reduce the success rate of IVF. In addition, too old women may also be accompanied by other potential health problems, such as hypertension, heart disease, etc. These diseases may increase the risk of pregnancy. For men, the growth of age will lead to the decline of sperm quality, thus affecting the success rate of pregnancy. Therefore, the hospital generally recommends that women try three generations of IVF technology as early as possible before the age of 35.
The limitation of age on third-generation IVF is mainly because the quality and quantity of germ cells will decline with age, thus increasing the risk of pregnancy and the possibility of embryo malformation. Therefore, young couples usually have a higher success rate when choosing the third-generation IVF technology.
2. Other serious health problems
The existence of other serious health problems is also one of the contraindications of the third-generation IVF. For example, couples with serious heart disease, kidney disease, liver disease or lung disease and other physical diseases may increase the risks during pregnancy and delivery, and pose a serious threat to the health of couples.
For couples with a serious genetic history, it is also necessary to carefully consider whether to carry out the third generation IVF technology. If both parents carry pathogenic genes, the embryo may suffer from genetic diseases, which may affect the health of the child.
3. Psychological and economic endurance
The third generation IVF technology is not an inexpensive option, which requires a lot of time and money. Therefore, couples need to assess their psychological and economic affordability when considering whether to carry out third-generation IVF technology. If they can't bear the cost, or can't bear the long-term treatment process and psychological pressure, couples may need to reconsider whether to try this technology.
In addition, the third-generation IVF technology is not always successful, and it may require multiple attempts to successfully conceive. Therefore, couples need to have enough patience and perseverance to face failures and setbacks.
4. Legal and ethical factors
Finally, the use of third-generation IVF technology is also limited by some legal and ethical factors. At present, China's laws and regulations on third-generation IVF technology are relatively strict, requiring approval from relevant departments, and can only be carried out in specific hospitals. Couples need to understand and comply with relevant laws and regulations, and also need to seriously consider whether to use this technology at the ethical level.
summary
The contraindications of third-generation IVF recognized by some hospitals in Shanghai include age restrictions, other serious health problems, psychological and economic affordability, and legal and ethical factors. Although the third-generation IVF technology provides a hope for couples who are unable to conceive naturally, it is necessary to carefully consider the couple's own situation and understanding of the technology to determine whether it is suitable for this technology.
