Concept and principle of IVF and e-ultrasound
IVF is an assisted reproductive technology, also known as in vitro fertilization embryo transfer (IVF-ET). It is a method to realize pregnancy and fertility by fertilizing female eggs and male sperm in vitro, cultivating them into embryos, and then transplanting them back to the female uterus.
E ultrasound is a high frequency ultrasound technology, which is used to examine women's ovaries and uterus through electronic ultrasound instruments. It can help doctors monitor the development of follicles, the thickening of endometrium and ovulation, so as to help determine the appropriate time for IVF operation.
Operation process of IVF e-ultrasound
The operation of IVF e-ultrasound is mainly divided into the following steps:
The first step is to inject ovulation promoting drugs under the guidance of ultrasound. In order to increase the quantity and quality of eggs, women will inject ovulation promoting drugs at the beginning of menstruation to promote ovarian development and ovulation.
The second step is to check the follicular development by ultrasound. After the injection of ovulation promoting drugs, the doctor can use transvaginal ultrasound probe or abdominal wall ultrasound probe to examine the female ovary. The doctor will observe the size and number of follicles to determine the appropriate time for egg retrieval.
The third step is egg retrieval. Under the guidance of ultrasound, doctors will take eggs at an appropriate time. Ovulation is usually performed 36 hours before ovulation, and the mature eggs in the ovary are taken out through colposcopy or puncture technology.
The fourth step is in vitro fertilization and embryo culture. The extracted eggs and male sperm are fertilized in vitro in the laboratory. After cultivation and observation, doctors select high-quality embryos for transplantation.
The fifth step is embryo transfer. Under the guidance of e-ultrasound, doctors will place the selected embryos into women's uterus through vagina for embryo transfer. After transplantation, women need to rest and observe, waiting for the results of pregnancy.
Advantages and risks of IVF e-ultrasound
IVF e-ultrasound technology has the following advantages:
1. Improve the pregnancy success rate. E ultrasound can help doctors to determine the right time for IVF operation and improve the success rate of pregnancy.
2. Monitor the embryonic development. E ultrasound can observe the development of embryos, help doctors select the embryos most likely to be implanted for transplantation, and improve the success rate.
3. Reduce the risk of multiple pregnancy. The risk of multiple pregnancy can be reduced by determining the appropriate time of embryo transfer through e-ultrasound.
At the same time, IVF e-ultrasound technology also has some risks:
1. Risk of ovum retrieval operation. Ovarian trauma and infection may be caused by ovum retrieval, but these risks are low under standard operation.
2. Risk of embryo transfer failure. Even with the assistance of e-ultrasound technology, embryo transfer may still fail.
3. Risk of pregnancy complications. The risk of early pregnancy reaction, pregnancy hypertension, pregnancy diabetes and other complications of IVF pregnancy may be slightly increased.
Introduction to the application of test tube baby e-ultrasound in hospitals
In vitro baby e-ultrasound technology has been widely used in many large general hospitals and reproductive medical centers in China. Take the "Beijing Union Medical College Hospital Reproductive Center" as an example. The hospital is one of the first established reproductive centers in China and has rich experience in the field of reproductive technology. The hospital provides a series of assisted reproductive technologies such as test tube baby, e-ultrasound, embryo transfer, and is equipped with advanced medical equipment and professional medical team to provide comprehensive services for infertile couples.
Summary
In vitro fertilization, embryo culture and transplantation under the guidance of e-ultrasound, which is an assisted reproductive technology, has improved the success rate of IVF. This technology has been widely used in hospitals and reproductive centers, such as the Reproductive Center of Peking Union Medical College Hospital. However, IVF e-ultrasound technology also has certain risks and complications, requiring patients to operate under the guidance of doctors.
