Difference between IVF and IVF
IVF and artificial insemination are important achievements of modern medical technology in assisted reproduction. They are both ways to help couples who cannot conceive naturally achieve their reproductive aspirations. However, there are some differences between IVF and IVF in process, success rate and technical means.
1. Different processes
IVF is achieved through in vitro fertilization. The specific process includes: first, women receive hormone therapy to promote the simultaneous development of multiple follicles; Then, doctors use ultrasound guided fine needles to extract mature eggs; Then, the eggs are artificially fertilized with sperm provided by men in the laboratory; Finally, the fertilized eggs were cultured for several days, and the high-quality embryos were transferred back to the female uterus to complete the pregnancy. Artificial insemination is to inject male sperm directly into female uterus, so that sperm can naturally combine with eggs in the body to fertilize.
From the perspective of the whole process, IVF requires more technical environment and medical operations, while IVF is relatively simple. IVF needs to monitor the development of eggs and embryos and carry out procedures such as embryo culture and transfer, while artificial insemination mainly involves the removal and injection of sperm, which is simple and does not require in vitro culture.
2. Different success rates
The success rate of IVF is relatively high, especially for couples with low female ovarian function or complicated infertility reasons. According to the actual situation, the success rate of IVF is usually between 40% and 60%, but it may fluctuate due to various factors. However, the success rate of artificial fertilization is relatively low, between 20% and 30%, because its success depends largely on the quality of women's own eggs and the fertilization environment.
IVF has obvious advantages because it can improve the success rate through a variety of technical means. For example, ICSI (single sperm injection technology) can solve the problem of low sperm quality in men, and PGD (preimplantation gene diagnosis) can avoid the transmission of certain genetic diseases.
3. Different technical means
In IVF, there are two common technical means that are indispensable. One is in vitro fertilization (IVF), in which eggs and sperm are fertilized in the laboratory. The other is embryo transfer (ET), which is to transfer high-quality embryos that have been cultured and screened into the uterus of women.
Artificial insemination mainly relies on the technology of sperm injection, which directly injects sperm into the female uterus to play its role in natural fertilization.
Both of these technologies require superb medical technology, but IVF requires more laboratory equipment and operations, which is relatively difficult.
4. Difference in medical environment
IVF and IVF generally need to be carried out in formal reproductive medicine hospitals. IVF requires hospitals to have complete assisted reproductive technology equipment and advanced laboratory conditions to ensure the success of the culture and transfer of fertilized embryos. Artificial insemination is relatively simple, and the requirements for hardware facilities in hospitals are relatively low.
Different hospitals have differences in equipment, technical strength and success rate. Choosing a suitable hospital is crucial to the probability of successful pregnancy and the psychological status of patients.
summary
To sum up, there are some differences between IVF and IVF in process, success rate, technical means and medical environment. IVF has high success rate, complicated technology and high medical environment requirements; However, artificial insemination is relatively simple, with low success rate and low requirements for medical environment. Different couples can choose appropriate fertility assistance technology according to their own conditions to achieve their fertility aspirations.
