What are the technologies for IVF selection?



Techniques for IVF selection

IVF selection technology, also known as reproductive medicine technology, is an assisted reproductive medicine method designed to help couples who cannot conceive naturally to successfully conceive and give birth to healthy children. The following will elaborate on the current common IVF selection technology from four aspects: genetic testing, gender selection, embryo screening and drug assisted technology.

1. Genetic testing

Genetic testing is a technology to screen some genetic diseases, traits and characteristics by detecting the genome of embryos or individuals before pregnancy. Through this technology, it is possible to determine what genetic disease risks are carried before conception, so as to avoid passing the disease on to offspring. Genetic detection techniques mainly include the following methods. First, the common one is single gene disease detection, which is used to detect some known single gene diseases, such as cystic nephropathy, congenital deafness, etc. This technology can further select healthy embryos for transplantation through gene detection of embryos or embryo carriers. Secondly, there is chromosomal screening of structural abnormalities, which can determine whether there are chromosomal abnormalities in the embryo, such as Down's syndrome, Edwards syndrome, etc. This technology can screen out embryos with normal chromosomes, and improve the success rate of IVF and the probability of giving birth to healthy children. In addition, there are chromosome male and female detection, which is used to determine the sex of the embryo. This technology can meet the gender preference of some families.

2. Gender selection

In reproductive medicine technology, gender selection is a technology that couples are very concerned about. Some couples want to choose the gender of their future children for the sake of life and family balance. There are two main methods of sex selection, one is to screen the sex by means of genetic detection, the other is to select the sex by means of artificial assistant technology. In terms of genetic gene testing, we can determine the sex of the embryo through gene analysis, and then select the embryo with healthy sex for transplantation. In terms of artificial assistant technology, such as artificial insemination, pregnancy can be selected according to the sex of sperm. Although these technologies can realize gender selection, they still need to be carried out on the premise of abiding by relevant laws and regulations and ethics.

3. Embryo screening

Embryo screening is an important method in IVF selection technology, which aims to ensure the healthy and normal development of the transferred embryos. Embryo screening techniques mainly include the following. First of all, the common one is the evaluation of embryo morphology. By observing and evaluating the appearance, cell number, embryo structure and other factors of the embryo, we can judge its development quality and health status. This technique can eliminate abnormal embryos and improve the success rate of embryo transfer. Secondly, there is the chromosome karyotype detection of the embryo. By detecting the chromosome karyotype of the embryo, we can determine whether there are chromosome abnormalities in the embryo, such as chromosome number abnormalities, structural abnormalities, etc. This technique can select embryos with normal chromosomes for transplantation and reduce the risk of chromosomal abnormalities in children. In addition, there are emerging embryo screening technologies such as gene expression profile analysis, which can predict the health status and development potential of embryos by analyzing the gene expression of embryos, and further improve the success rate of IVF and the probability of having healthy children.

4. Drug assisted technology

IVF selection technology also includes some drug assisted technologies, aiming to improve women's fertility and the success rate of IVF. Drug assisted technology mainly includes the following. First of all, ovulation promoting drugs are drugs that can promote ovarian development and ovulation, and enhance the chance of pregnancy by controlling ovarian ovulation. These drugs can help women produce more eggs, control ovarian ovulation time, and improve the success rate of fertilization and embryo transfer. Secondly, hormone replacement therapy is a common drug assisted technology, which is used to adjust the hormone level in women and improve the implantation rate of fertilized eggs. This technology mainly promotes embryo implantation and embryo development by supplementing women with estrogen, progesterone and other hormones. In addition, there are auxiliary technologies such as anticoagulants, which are used to increase blood fluidity and reduce blood coagulation, thus improving the implantation rate of embryos and the success rate of transplantation. To sum up, IVF selection technology is a comprehensive application of a series of assisted reproductive medicine technologies, including genetic testing, gender selection, embryo screening and drug assisted technology. These technologies, through scientific and medical methods, help couples realize their desire to become pregnant and have healthy children. However, it should be noted that when selecting technology for IVF, relevant laws, regulations and ethics should be observed to ensure the legitimacy and safety of technology.
