We all know that in vitro fertilization technology can be divided into the first generation, second generation, and third generation. However, many people are not very familiar with these three generations of in vitro fertilization technology, only knowing that the third generation is the most advanced. Indeed, the third generation is developed on the basis of the second generation. So what is the difference between the third generation and the second generation? Let's take a closer look.

IVF technology has enabled many families to have a child and helped them achieve their reproductive goals. In fact, the first generation of IVF technology was aimed at female infertility, the second generation was aimed at male infertility, and the third generation was aimed at some men and women with genetic diseases.

What does the third generation in vitro technology mean

The third generation in vitro fertilization technology, also known as pre implantation genetic diagnosis/screening, refers to the method of analyzing the genetic material of embryos before IVF-ET embryo transfer, diagnosing any abnormalities, screening healthy embryo transfer, and preventing the transmission of genetic diseases.

From a layman's perspective, the third generation in vitro technology is developed on the basis of the first and second generations. After removing the egg and sperm to combine, the embryo is cultured into a blastocyst, and the genetic material in the cells is checked to select the healthiest embryo and transplant it into the uterus, in order to achieve the goal of preventing genetic diseases.

Compared to the second generation technology, the third generation in vitro technology involves an additional step of analyzing the genetic material of embryos, resulting in significantly higher costs. However, its advantage lies in the ability to select advantageous embryos for transplantation, which can improve the success rate.

For women over 35 years old, due to age issues, the rate of chromosomal abnormalities in eggs may increase, and third-generation technology can minimize these risks and prevent many specific genetic diseases.

Differences between second-generation and third-generation in vitro technology

There are significant differences between second-generation IVF and third-generation IVF. The second-generation IVF technology is single sperm injection technology, while the third-generation IVF technology is screening and diagnosis before embryo transfer. There are four main differences between the two:

1. Differences in technical operations

The second generation technology typically involves injecting sperm into the egg under a high-definition microscope through specialized needles to fertilize it, while the third generation screens and analyzes genetic material before blastocyst transplantation.

2. Adapt to differences in population

The second generation of test tubes is mainly aimed at the male population, while the third generation is not only targeted at individuals with genetic diseases, but also for other populations, with a much wider range of adaptability.

3. Differences in fees

Compared to the third generation, the cost of the second generation is definitely cheaper. Generally, the second generation in China costs around 30000 to 50000 yuan, while the third generation costs around 100000 yuan.

4. Differences in domestic policies

In China, the use of third-generation technology is restricted, while the second-generation has no restrictions.

Is the third-generation test tube technology mature

The third-generation IVF technology has developed to this day and is already very mature in terms of technology. However, China started relatively late in this field, and most of it can only be done in tertiary hospitals in some large cities.

Through the above reading, you must have known the differences between the third generation IVF and the second generation. In fact, IVF technology is currently very mature, and the cost is higher than the second generation. The success rate is naturally higher, mainly because it can screen for specific genetic problems, which is a choice for many people.
