Specific steps and success rate of IVF
IVF, also known as assisted reproductive technology (ART), is a way to help couples who cannot conceive naturally achieve their reproductive aspirations. It can help couples who have experienced multiple unsuccessful pregnancies, female fallopian tube abnormalities, male sperm problems or specific genetic diseases. At present, the IVF technology is gradually mature worldwide, and the success rate is also increasing.
Specific steps
The specific steps of IVF include the following main stages:
1. Pregnancy preparation examination: The couple went to the hospital for a comprehensive physical examination, including semen examination, ovarian function examination, etc., to determine whether the maternal and paternal physical conditions are suitable for IVF.
2. Ovulation promotion therapy: Stimulate ovarian development by giving female hormone drugs, promote the maturation of multiple follicles, and monitor the size and number of follicles.
3. Egg collection and sperm donation: After the ovary is fully developed, the doctor will collect eggs in the operating room. At the same time, men also need to provide fresh semen samples.
4. In vitro fertilization: under laboratory conditions, the collected eggs are fertilized in vitro with fresh or frozen sperm.
5. Embryo culture: The fertilized eggs are cultured in the laboratory for 2 to 6 days to form multiple embryos that are exactly developing.
6. Embryo transfer: select the best embryo and implant it into the mother's uterus.
7. Pregnancy detection and maintenance: pregnancy detection shall be carried out within two weeks after embryo transfer to confirm whether the pregnancy is successful. If the pregnancy is successful, continue the pregnancy maintenance treatment, and carry out necessary inspection and monitoring.
How high is the success rate?
The success rate of IVF is affected by many factors, including age, ovarian reserve, uterine condition, sperm quality, etc. In addition, the professional level and equipment of the hospital also have a certain impact on the success rate.
The success rate data of hospitals and clinics in different countries vary depending on their statistical methods, but generally it is between 20-30%. For example, some well-known hospitals such as Peking Union Medical College Hospital, Shanghai Zhongshan Hospital, and the Chinese University of Hong Kong have rich experience in IVF technology, and their success rate is high.
Of course, the success rate is not absolute. IVF may need multiple cycles to successfully conceive. Some factors such as suffering from other diseases and old age will reduce the success rate.
Therefore, when choosing the IVF process, couples should not only consult doctors, but also understand their own situation and treat the success rate rationally. Comprehensive understanding and reasonable planning will provide more possibilities for successful pregnancy.
Summary
As an assisted reproductive technology, IVF can help couples who are unable to conceive naturally achieve their reproductive aspirations. The specific steps include pregnancy preparation examination, ovulation induction treatment, egg collection and sperm donation, in vitro fertilization, embryo culture, embryo transfer, pregnancy detection and maintenance. The success rate is influenced by many factors, generally between 20-30%. Choosing professional hospitals and reasonable planning can improve the possibility of successful pregnancy.
