What are the differences between the first generation and the second generation of IVF?
The emergence of IVF technology provides a birth choice for couples who cannot conceive naturally. With the development of science and technology, IVF technology is also making continuous progress, from the first generation to the second generation. There are many differences between the first generation and the second generation of IVF, which will be described in detail below.
1. Pregnancy rate and success rate
The pregnancy rate of the first generation of IVF is relatively low, because only a single sperm and egg combine during fertilization, so the probability of successful pregnancy is small. However, the pregnancy rate of the second generation of IVF babies has significantly increased, which is due to the introduction of assisted reproductive technologies, such as embryo culture and genetic screening. These technologies have effectively improved the quality and health of embryos and increased the possibility of pregnancy.
Similar to the pregnancy rate, the success rate of IVF generation is also low. Due to technical limitations and the lack of effective embryo screening methods, sometimes it may take multiple attempts to successfully conceive. The success rate of the second generation of test tube babies has increased significantly. In most cases, only one attempt is needed to successfully conceive. This is mainly due to the continuous progress of technology and the improvement of embryo screening methods.
2. Embryo quality
The embryo quality of the second generation of IVF is higher than that of the first generation. In the generation of test tube babies, doctors usually can only select the embryos with the most development potential for transplantation, but they cannot exclude some embryos with genetic defects or chromosomal abnormalities. The second generation of IVF has introduced embryonic genetic screening technology, which can carry out chromosome screening and gene mutation detection on embryos, select the healthiest embryos for transplantation, thus reducing the risk of birth defects.
3. Risk of complications
In the generation of test tube babies, there are some risks of complications, such as ovarian hyperstimulation syndrome (OHSS) and multiple pregnancy. The second generation of test tube babies reduced the incidence of OHSS by improving technology and controlling the use of ovarian stimulating drugs. In addition, the risk of multiple pregnancy is greatly reduced by selecting only a single embryo for transfer during embryo transfer.
4. Costs and expenses
The cost of IVF treatment is an important consideration. The treatment cost of the IVF generation is relatively high, which is due to the relatively low level of technological advancement and the need for multiple attempts to succeed. The cost of IVF II is relatively low. With the continuous improvement of technology and the improvement of the success rate, it usually takes only one attempt to succeed, thus reducing the treatment cost.
To sum up, there are significant differences between the first and second generations of IVF in terms of pregnancy rate and success rate, embryo quality, complication risk and cost. Compared with the first generation, the second generation of IVF has made many improvements in technology and treatment methods, which can better solve the problem of infertility, improve the pregnancy and success rate, reduce the risk of embryo defects, and be more affordable economically. With the further development of science and technology, it is believed that IVF technology will also continue to progress and improve, bringing more hope to couples who are eager to have healthy babies.
