What assisted reproductive technology can be used for advanced pregnancy preparation?

With the development of society and the increasing demand for childbearing age, more and more women choose to postpone childbearing. However, due to the decline of ovarian function, poor egg quality and other factors, the elderly pregnant women often face higher fertility problems. In order to help these women realize their wishes, modern medicine provides a variety of assisted reproductive technologies. Next, we will introduce what assisted reproductive technology can be used for pregnancy preparation at an advanced age from different perspectives.

1. IVF technology

IVF technology is a common method in assisted reproductive technology. For the elderly pregnant women, if it is difficult to conceive normally, they can choose the IVF technology. This technology combines the egg and sperm to form a fertilized egg through in vitro fertilization, and then transfers the fertilized egg into the uterus to continue its development and implantation.

The success rate of IVF technology mainly depends on the quality of eggs and sperm. Therefore, for the elderly pregnant women, it may be necessary to improve the success rate of pregnancy by using young women's donated eggs or frozen eggs. In China, some large general hospitals, such as Peking Union Medical College Hospital and Ruijin Hospital affiliated to Shanghai Jiaotong University, have set up IVF centers to provide professional assisted reproductive technology services for elderly pregnant women.

2. Frozen egg technology

For the elderly pregnant women, the quality of eggs is very critical. With the growth of age, the number and quality of eggs gradually decline, which is easy to lead to difficulties in pregnancy and the occurrence of embryonic abnormalities. Therefore, frozen egg technology has become a method that can collect and retain eggs at an appropriate age.

The frozen egg technology is to freeze and store the eggs in vitro, and then unfreeze them when needed. This technology can effectively preserve the quality of eggs and improve the chances of pregnancy for elderly pregnant women. There are egg freezing centers in Beijing Chaoyang Hospital affiliated to Beijing Medical University, Children's Hospital affiliated to Shanghai Jiaotong University and other well-known hospitals, which can provide high-quality frozen egg technical services for women.

3. PGD/PGS technology

PGD (genetic diagnosis in early pregnancy) and PGS (genetic screening before embryo implantation) are assisted reproductive technologies, which can conduct genetic testing on the fertilized egg when it has reached a certain stage of development, and screen out existing chromosome abnormalities or genetic diseases. This technique is very useful in the advanced pregnancy preparation, which can avoid the embryo malformation caused by the decline of egg quality.

Through PGD/PGS technology, we can screen the fertilized eggs, select normal embryos for transplantation, and improve the success rate of pregnancy and the probability of having a healthy baby. Some large general hospitals, such as Beijing Tsinghua Changgeng Hospital affiliated to Tsinghua University and Xiangya Hospital of Central South University, are equipped with PGD/PGS technology and have rich clinical experience to provide professional assisted reproductive technology support for elderly pregnant women.

4. Chemical pregnancy/artificial cycle control

For the elderly pregnant women, due to the decline of ovarian function, there may be irregular menstrual cycle and other problems, which will affect the implantation of fertilized eggs and the smooth development of embryos. To solve this problem, we can help regulate the menstrual cycle through chemical pregnancy and artificial cycle control.

Chemical pregnancy refers to the use of drugs to control women's menstrual cycle, thereby improving the chance of pregnancy. The artificial cycle control is to help regulate the ovarian function and promote the development and ovulation of eggs by giving women specific hormones. The First Affiliated Hospital of Fujian Medical University, the First Hospital of Hebei Medical University and other hospitals provide chemical pregnancy and artificial cycle control services.

To sum up, the elderly pregnant women can choose assisted reproductive technologies such as IVF technology, frozen egg technology, PGD/PGS technology and chemical pregnancy/artificial cycle control. These technologies can help women increase their chances of pregnancy and increase the likelihood of having a healthy baby. However, the choice of technology and whether it is suitable still need to be determined according to personal conditions and doctor's recommendations.
