How to avoid genetic diseases in IVF?

Test tube babies are babies bred in the laboratory through assisted reproductive technology, so they may carry some genetic diseases. However, through a series of screening and testing, the occurrence of genetic diseases in IVF can be effectively avoided. This article will elaborate on the screening of genetic diseases, selection of normal embryos, genetic counseling and assisted selection technology.

1. Screening of genetic diseases

The screening of genetic diseases is carried out before IVF pregnancy, aiming to detect whether the patient or his family carries a genetic disease gene. At present, the commonly used screening methods for genetic diseases include genetic counseling, family history investigation, gene testing, etc. First of all, genetic counseling refers to that the counselor provides relevant genetic counseling and advice according to the condition of patients or their families' genetic diseases. Secondly, family history survey is to collect the family history of patients and their relatives, and analyze the transmission rule and risk of genetic diseases in the family. Finally, gene detection can determine whether to carry genes related to genetic diseases by analyzing individual gene information. In the process of genetic disease screening, doctors will conduct relevant analysis and determination according to different types of genetic diseases, so as to provide basis for subsequent treatment and selection of normal embryos.

2. Select normal embryos

Selecting healthy embryos is an important part of IVF genetic disease prevention. Preimplantation gene diagnosis (PGD) is a key screening technology in IVF technology. It detects whether there are genes related to genetic diseases through genetic analysis of embryos. The specific process of PGD is that doctors take out one or more cells in the early stage after IVF and carry out gene detection and analysis on them. Based on these results, embryos without genetic disease genes or potential genetic diseases can be screened to increase the probability of successful pregnancy and healthy baby birth. The key to selecting normal embryos lies in the early diagnosis and accurate analysis of genetic diseases to ensure the best results.

3. Genetic counseling

Genetic counseling is another important part of IVF genetic disease prevention. In IVF technology, genetic counselors will conduct detailed genetic disease risk assessment for patients and give targeted suggestions and guidance. The process of genetic counseling includes collecting information about patients' genetic diseases, assessing disease risks, and providing patients with preventive measures for genetic diseases based on their personal conditions. The consultant will continue to follow up the treatment and birth process, provide necessary support and guidance, and ensure the best effect of the medical plan. Genetic counseling can help patients better understand their genetic status and the risk of genetic diseases, follow the doctor's recommendations for reasonable treatment and birth planning, and minimize the risk of genetic diseases.

4. Assisted selection technology

Assisted selection is one of the effective tools to avoid genetic diseases in IVF. Assisted selection techniques include preimplantation gene diagnosis (PGD) and fetal sex selection. In addition to the previously mentioned PGD technology, fetal sex selection is also a common assisted selection technology. Through chromosome screening and analysis, doctors can predict the sex of pregnant embryos and select embryos with normal sex before implantation. The application of assisted selection technology can improve the success rate of IVF pregnancy, reduce the risk of genetic diseases, and help patients to achieve gender selection of their children.

summary

Through a variety of measures such as screening of genetic diseases, selection of normal embryos, genetic counseling and assisted selection technology, the occurrence of genetic diseases in IVF can be effectively avoided. This comprehensive treatment scheme can ensure the health and reproductive success of IVF to the greatest extent. For couples with a history of genetic diseases or worried about the risk of genetic diseases, taking the above measures actively is the key to ensure the health of IVF.
