Definition of IVF and IVF
IVF and IVF are both types of assisted reproductive technology. In vitro fertilization embryo transfer (IVF-ET) is also called in vitro fertilization embryo transfer (IVF-ET), which refers to the combination of female eggs and male sperm in vitro test tubes and culture into embryos, and then transfer the embryos to the female uterus for pregnancy. Artificial insemination refers to the direct injection of sperm into a woman's uterus through medical means to make her pregnant and give birth to a baby.
Difference in fertilization process
The fertilization process of IVF includes four stages: ovulation induction, oocyte retrieval, fertilization and embryo transfer. In the ovulation promotion phase, women inject drugs to increase the number of ovulation and improve the pregnancy rate. Then, under the guidance of ultrasound, doctors extract eggs from the uterus. Men provide sperm samples and combine them with eggs in the laboratory. While artificial fertilization only involves fertilization, that is, the processed sperm is injected into the uterus of a woman, and pregnancy is achieved through the natural fertilization of the egg.
In the process of IVF, eggs and sperm are cultured into embryos in vitro, and doctors will observe the development of embryos and select the most suitable embryos for transplantation into women's uterus. While artificial fertilization does not involve the process of selecting embryos, it just directly injects sperm into the vagina or uterus of a woman to allow the embryo to develop in the natural environment.
In addition, if there are surplus embryos during IVF, they can be frozen. In this way, frozen embryos can be transferred in the future. However, artificial insemination does not involve the freezing of embryos.
Applicable etiology difference
Test tube baby is suitable for women with serious fallopian tube disease or obstruction, polycystic ovary syndrome, anovulation, uterine factors and other reproductive problems. At the same time, it is also suitable for men with abnormal semen such as low sperm count and low motility. With IVF technology, these physiological problems can be bypassed to achieve pregnancy and delivery.
Artificial insemination is suitable for women without obvious reproductive problems, but the quality of male semen is poor, such as insufficient sperm or poor vitality. By directly injecting sperm into women's uterus, it makes up for the lack of male fertility and realizes pregnancy.
Success rate and cost
The success rate of IVF is relatively high, which is about 30%~60% according to the different conditions of hospitals and individuals. The cost is also high, involving drug costs, surgery costs, device use costs and other aspects of expenditure. The specific cost varies according to the region and hospital, and generally ranges from tens of thousands to hundreds of thousands of yuan.
The success rate of artificial insemination is slightly lower than that of IVF, about 15%~30%, because the whole process of fertilization and embryo development is carried out in the female body. If the female uterine environment is not suitable, the fertilized embryo will be difficult to implant. The cost is relatively low, mainly including the cost of doctors' diagnosis and treatment and the cost of equipment used, which is generally between thousands and 10000 yuan.
Summary of differences between IVF and IVF
To sum up, there are differences between IVF and IVF in fertilization process, applicable causes, success rate and cost. IVF is suitable for couples with multiple reproductive problems by cultivating embryos in vitro, with high success rate and relatively high cost. While artificial insemination is applicable to couples without obvious reproductive problems. The success rate is slightly lower than that of IVF, and the cost is relatively low. According to personal conditions and doctors' suggestions, couples can choose their own assisted reproductive technology to achieve their reproductive aspirations.
