Definition of IVF
In vitro fertilization embryo transfer (IVF-ET) babies, also known as in vitro fertilization embryo transfer (IVF-ET) babies, are babies who develop and are born by transferring fertilized eggs into the mother's womb during in vitro fertilization and embryo culture through assisted reproductive technology. This technology was successfully applied for the first time in the 1970s, and has been continuously developed and promoted in the following decades.
Implementation process of IVF
The implementation process of IVF is generally divided into the following steps:
The first step is to take eggs: after hormone treatment, women develop their ovaries and discharge multiple mature eggs. This process usually needs to be carried out in the hospital to ensure the safety and accuracy of the operation.
The second step is sperm extraction: the male provides semen samples, and then separates the sperm with high vitality and complete structure through centrifugation and other methods.
The third step is in vitro fertilization: the obtained eggs and sperm are fertilized in vitro in the laboratory. Usually, a certain amount of sperm is added around the egg in the culture dish to increase the success rate of fertilization.
Step 4: Embryo culture: After several days of culture, the fertilized egg develops into a relatively stable embryo, usually 2 to 5 days. During this process, the number and development of embryos will be closely monitored.
Step 5: Embryo transfer: select the most promising embryos and transfer them back to the uterus of women by vaginal or intraperitoneal injection. This procedure usually requires no anesthesia and is a relatively simple operation.
Step 6: Observation and pregnancy detection: After transplantation, women need to have a period of rest and observation to improve the probability of embryo implantation and development in the uterus. After about two weeks, pregnancy hormone levels can be measured in blood or urine to determine whether the pregnancy is successful.
Success rate and risk of IVF
The success rate of IVF is affected by many factors, including female age, the quality of eggs and sperm, and the professional level of doctors and laboratories. Generally speaking, young and healthy women have a higher success rate, while older women or women with some reproductive problems have a lower success rate.
In addition to the success rate, IVF also has some risks. Hormone therapy may cause some side effects, such as ovarian hyperstimulation syndrome; Sometimes it takes many attempts to succeed, which increases economic and psychological pressure. In addition, compared with other forms of pregnancy, IVF is more likely to lead to multiple pregnancies, increasing the risk of premature delivery and other related complications.
Test tube baby practice in some hospitals
Worldwide, IVF technology has been widely used. The following are some hospitals with good reputation in the field of IVF:
1. Fertility Clinic in New York, USA: The clinic has advanced laboratory equipment and a professional team to provide personalized IVF treatment programs through comprehensive assessment of patients' conditions.
2. Japan National Adult Disease Research Center: The center adheres to a rigorous treatment attitude, carries out relevant research on IVF, and helps couples who cannot conceive naturally realize their dream of artificial pregnancy through cutting-edge technology and meticulous services.
3. Reproductive Medicine Center of Peking Union Medical College Hospital, China: The center has rich experience in the field of reproductive medicine, and has internationally leading reproductive technology and equipment. At the same time, the center focuses on the mental health of patients and provides detailed psychological guidance and support.
summary
In vitro fertilization (IVF) - embryo transfer (ET) is a method to help couples who are unable to conceive naturally to achieve fertility. The implementation process includes egg retrieval, sperm retrieval, in vitro fertilization, embryo culture, embryo transfer and pregnancy detection. The success rate is affected by many factors, but there are also risks and complications. Globally, some hospitals have advanced IVF technology and professional teams, which can provide personalized treatment plans and meticulous services for patients.
The emergence of IVF provides new birth options for couples who cannot conceive naturally, and brings them new hope and happiness.
