Definition and principles of IVF and AI
In Vitro Fertilization (IVF) is a kind of assisted reproduction technology. It helps infertile couples realize their dreams of fertility by culturing the fertilized eggs in vitro for a period of time and then transplanting them back to the mother. Artificial insemination is the direct injection of sperm into the female reproductive system to increase the chance of pregnancy. Both of these technologies are important breakthroughs in the field of reproduction in modern medicine, bringing hope to infertile couples.
The IVF technology mainly includes the following steps: first, by adjusting the menstrual cycle of women, control the ovarian function, and make multiple follicles mature; Then, take eggs from women and combine them with sperm provided by men in the laboratory; Then, the fertilized eggs are cultured for several days to form embryos; Finally, select the embryo with the most development potential and transplant it into the female uterus to wait for the occurrence of pregnancy.
Artificial insemination is to collect sperm and inject it into the female reproductive system directly through vagina, cervix or artificial assistant technology after simple treatment. This technique is applicable to men in couples who have problems such as abnormal semen or inability to ejaculate naturally, or to single women or people in need of help in same-sex couples.
Indications of IVF and AI
IVF is suitable for infertile couples caused by many reasons, such as female fallopian tube obstruction, endometriosis, ovarian dysfunction, etc; Male sperm quality is abnormal, semen cannot ejaculate naturally, and sperm survival rate is low. IVF is also suitable for some carriers of genetic diseases. The genetic screening before embryo implantation can reduce the risk of genetic diseases.
Artificial insemination is applicable to infertility caused by male factors, such as insufficient sperm, low motility or azoospermia. In addition, it can also help women without sexual partners or women in same-sex partners.
Success rate and risk of IVF and artificial insemination
The success rate of IVF is affected by many factors, such as female age, egg quality, quantity and quality of embryo implantation, etc. According to statistics, the success rate is generally between 30% and 50%. However, IVF technology also has certain risks, such as increased risk of overweight and premature infants, risk of multiple pregnancies and possible complications during treatment.
The success rate of artificial insemination is relatively low, usually between 10% and 20%. The main risks include the risk of infection, endometriosis and multiple pregnancy. In addition, due to the limitation of sperm sources, the success rate of artificial insemination will be further reduced.
Fees and hospital recommendations for IVF and AI
The cost of IVF is relatively high, including the cost of early examination, the cost of taking eggs and the cost of embryo transfer. According to the charging standards of different regions and hospitals, the fees may range from tens of thousands to hundreds of thousands. In China, large general hospitals such as Peking Union Medical College Hospital and Fudan University Affiliated Obstetrics and Gynecology Hospital all provide IVF technology.
The cost of artificial insemination is relatively low, usually between several thousand and ten thousand yuan. Some large public hospitals and private reproductive hospitals will provide artificial insemination services, such as Renji Hospital affiliated to Shanghai Jiaotong University School of Medicine, Wuhan First Hospital, etc.
summary
Test tube baby and artificial insemination are two commonly used methods in assisted reproductive technology. Test tube baby is suitable for infertile couples with multiple reasons, which can improve the pregnancy success rate. Artificial insemination is applicable to infertility caused by male factors, and also provides fertility opportunities for women without sexual partners. However, both of these technologies have certain risks and cost pressures. It is recommended that patients consult professional doctors for evaluation and decision-making when choosing hospitals and technologies.
