Success rate of IVF
In vitro fertilization embryo transfer (IVF-ET) is a kind of assisted reproduction technology, which combines eggs and sperm in the laboratory, and then transfers the fertilized eggs into the female uterus to conceive the baby. Test tube baby technology has gradually become an effective means for infertile couples to realize their dreams of healthy babies. However, the success rate of IVF depends on many factors.
Effect of embryo quality
Embryo quality is one of the most important factors affecting the success rate of IVF. In the laboratory, embryo quality will be evaluated according to its morphology and development. Better embryo quality means higher success rate. Generally, high-quality embryos have correct cell division number, uniform cell size and good shape. Some hospitals, such as Beijing Tsinghua Changgeng General Hospital, use advanced embryo evaluation techniques to screen high-quality embryos, thus improving the success rate of IVF.
In addition, the embryo quality is also affected by the patient's age. With the growth of age, the quality of female eggs will decline, thus affecting the formation and development of embryos. Therefore, the success rate of IVF for older women is relatively low.
Impact of patients' underlying diseases
IVF may affect the success rate of patients with certain basic diseases. For example, endometriosis, hysteromyoma and other diseases may affect the probability of successful implantation of embryos into the uterus. Therefore, before IVF, the doctor will conduct a comprehensive physical examination of the patient to determine whether there is a basic disease, and then arrange the corresponding treatment plan to improve the success rate.
Use and Regulation of Pregnancy Aids
Pregnancy aid drugs are commonly used in IVF. Pregnancy aid drugs can regulate women's ovulation cycle, increase the quantity and quality of ovulation, and thus improve the probability of pregnancy. Common pregnancy aids include gonadotropin, human chorionic gonadotropin, etc. However, the use of these drugs needs the guidance and monitoring of doctors, and improper use may lead to side effects. In some hospitals, such as Shanghai Maternal and Child Health Care Center, doctors will develop personalized pregnancy aid drug use programs based on the specific conditions of patients to improve the success rate of IVF.
Time and expenses
The whole process of IVF usually takes 2-3 cycles to succeed. The first cycle is used to assess the patient's physique and diagnose potential problems, the second cycle is used for treatment, fertilization and transplantation, and the third cycle is used to monitor and adjust the treatment plan. Each cycle of IVF usually takes 2-3 weeks.
The cost of IVF varies with hospitals, medical programs and patients. According to the survey, the cost of IVF in mainland China is about 20000 to 100000 yuan. These costs include medical examination, auxiliary drugs, surgery costs, etc. For example, Peking Union Medical College Hospital has rich experience in IVF and a professional team, and its IVF costs are at a medium level in the market.
Summary
The success rate of IVF is affected by many factors, including embryo quality, patients' basic diseases, and the use and regulation of pregnancy aids. Better embryo quality, no underlying diseases and personalized pregnancy drug programs can improve the success rate. The IVF process usually takes 2-3 cycles, and the cost varies according to the hospital and patient conditions. When choosing IVF, patients should fully understand these factors and make decisions under the guidance of professional doctors.
