Difference between IVF and IVF

IVF and IVF are important breakthroughs in the field of assisted reproduction in modern medicine. Although they can help infertile couples achieve their reproductive dreams, there are obvious differences between the two in terms of operation methods, success rates and application scope. The following will elaborate on IVF and IVF from four aspects: birth mode, fertilization process, applicable population and success rate.

1、 Baby birth mode

IVF babies are usually born through in vitro fertilization embryo transfer technology. First, doctors will collect eggs from women's bodies, and then conduct in vitro fertilization with male sperm in the laboratory. When the fertilized egg develops into an embryo, the embryo is transferred back to the female uterus to make it naturally pregnant. Therefore, IVF is conceived through assistive technology, but the process of pregnancy and delivery is no different from that of naturally conceived infants. In artificial fertilization, the purified sperm is directly injected into the uterus of a woman, allowing the sperm to meet the egg and fertilize itself. Later, the process of pregnancy and delivery is the same as that of conventional pregnancy.

2、 Fertilization process

IVF process is more complex, involving multiple steps. The first is ovarian stimulation, which stimulates ovarian ovulation by using hormone drugs to obtain more mature eggs. Then, doctors will collect eggs by puncture. Next, the eggs and sperm are fertilized in vitro in the laboratory to promote the formation of fertilized eggs. Finally, the fertilized eggs are transplanted back into the female body for breeding. However, artificial insemination is relatively simple, and only needs to directly inject the treated sperm into the female uterus.

3、 Applicable population

Test tube babies are suitable for a variety of infertility conditions, including abnormal female ovarian function, poor male sperm quality, oviduct obstruction, etc. At the same time, it is also applicable to single women, gay couples and couples with genetic disease risks. However, artificial fertilization is mainly used in the case of poor quality or quantity of male sperm. The female fallopian tube is unobstructed, the egg quality is good, and there is no risk of genetic disease.

4、 Success rate

The success rate of IVF is relatively high. According to medical statistics, the success rate of IVF is usually between 30% and 50%, and with the continuous progress of medical technology, the success rate is still rising. The success rate of artificial fertilization is relatively low, generally between 10% and 20%. This is because IVF and embryo transfer can better screen sperm and eggs to avoid the production of bad embryos and improve the success rate of pregnancy. To sum up, there are significant differences between IVF and IVF in terms of infant birth mode, fertilization process, applicable population and success rate. IVF has a wide range of applications, complicated operation and high success rate, while IVF is usually used for male sperm problems, simple operation and low success rate. The selection of appropriate assisted reproductive technology needs to be balanced according to individual conditions and doctors' suggestions. Through the application of these technologies, it becomes more feasible for infertile couples to realize the dream of having a healthy baby.
