Specific methods for gestational weeks of test tube babies

IVF is a method of fertilizing eggs and sperm and cultivating them into embryos in vitro through assisted reproductive technology, and then transferring the embryos to the mother's uterus to continue pregnancy. The specific methods of IVF pregnancy week include selecting suitable embryos, transferring embryos, conducting pregnancy monitoring and providing appropriate support.

1. Breeding suitable embryos

In IVF technology, the right embryo is the key to the success of pregnancy. First, ovulation induction therapy is needed for women to ovulate multiple eggs. Later, doctors will use sperm and eggs for in vitro fertilization or choose single sperm injection method to fertilize eggs to form embryos. According to the quality, quantity and development of embryos, doctors will select the best embryos for transplantation according to different conditions. The next step is the embryo culture process, which usually lasts for 3-5 days. During this process, the development of the embryo will be monitored and evaluated. Doctors will evaluate the number, shape, number of cells, fragmentation and other indicators of embryos, and select the best embryo for transplantation to improve the success rate of pregnancy.

2. Embryo transfer

Embryo transfer is an important step in IVF pregnancy. In a specific cycle, the doctor will transfer the selected embryo into the female uterus through the endometrium to achieve pregnancy. Fresh or frozen embryos can be selected for embryo transfer. In the process of fresh embryo transfer, doctors will transport embryos into the uterus through endoscope or other auxiliary equipment. This process is usually carried out in the operating room and requires anesthesia. In frozen embryo transfer, the embryo will be thawed at a certain time, and then delivered to the uterus through hysteroscopy.

3. Pregnancy monitoring

After transplantation, patients need to receive pregnancy monitoring. The purpose of this process is to confirm whether the pregnancy is successful, and to detect whether there are abnormalities in time. Common monitoring methods include blood HCG level monitoring and uterine ultrasound. Blood HCG level monitoring usually starts from 10-14 days after transplantation, and pregnancy can be judged by observing the change of HCG level. If the HCG level rises, it usually means that the pregnancy is successful. Ultrasonography can observe whether there is embryo implantation in the uterus and assess the health of pregnancy.

4. Provide appropriate support

The doctor will provide appropriate support for IVF patients throughout the pregnancy. This includes psychological guidance, nutrition guidance and drug treatment. In the process of IVF, patients may face difficulties from emotion and pressure. Psychological counseling can help patients deal with emotional problems and reduce anxiety. In addition, doctors will also provide reasonable dietary guidance for patients, so that they can get adequate nutritional support. Some patients may also need to take some drugs to increase the success rate of pregnancy or maintain the stable development of embryos. In general, the specific methods of IVF pregnancy week include selecting suitable embryos, transferring embryos, conducting pregnancy monitoring and providing appropriate support. These steps need to be carried out in professional hospitals, such as Peking Union Medical College Hospital and Ruijin Hospital affiliated to Shanghai Jiaotong University School of Medicine. Through reasonable operation and scientific management, the chance of success of IVF pregnancy week will be greatly improved, bringing new fertility hope to infertile couples.
