Contraindications and risks of IVF
IVF is an assisted reproductive technology, which is used to help couples who cannot conceive naturally achieve their reproductive aspirations. Although IVF technology has made significant breakthroughs in medicine, there are still some contraindications and risks that need attention. This article will elaborate on the contraindications and risks of IVF from four aspects: women's conditions, men's conditions, genetic diseases and psychological factors.
Women's conditions
Before IVF, women need to undergo a comprehensive assessment to ensure that their physical conditions are suitable for this technology. First, women's age is an important factor. The quality and quantity of eggs of women over 35 years old will gradually decline, increasing the difficulty of IVF success rate. In addition, when women suffer from severe hysteromyoma, severe adenomyosis, abnormal uterine morphology and other diseases, they cannot use IVF technology.
Secondly, whether women suffer from certain diseases will also affect the application of IVF. For example, women with serious cardiovascular disease, respiratory disease, kidney disease and immune system disease need to be treated and controlled before IVF.
In addition, women suffering from severe obesity and serious mental illness are not suitable for IVF. Obesity will affect the quality of eggs and the success rate of embryo implantation, while mental illness will adversely affect women themselves and their future children.
Male condition
In addition to women's conditions, men also need to meet certain conditions to be suitable for IVF. Men need a sufficient number of mature sperm for in vitro fertilization. If a man has severe sperm abnormalities or cannot provide enough sperm samples, it is not suitable for IVF. In addition, when men suffer from genetic diseases or some chronic diseases, they also need to be properly treated and controlled before IVF.
Genetic disease
IVF technology can help couples avoid the transmission of genetic diseases to a certain extent, but it cannot completely eliminate the risks. If couples carry genes of genetic diseases, genetic testing can be used to screen the genetic status of fertilized eggs. However, there may still be risks such as missing detection or gene mutation before implantation of fertilized eggs. In addition, some rare genetic diseases may not be screened through routine genetic testing, so couples should receive genetic counseling and genetic evaluation before IVF.
In addition, embryo selection in the process of fertilized egg transfer will also bring certain risks. For couples with multiple embryos to choose from, selecting the most suitable embryo implantation can improve the success rate of IVF, but it may also lead to implantation of chromosome abnormalities or other genetic problems of embryos.
psychological factor
The process of IVF has great psychological pressure on couples. If couples have psychological problems or have too much pressure, it may affect the success rate of IVF. Therefore, before IVF, couples should try to maintain psychological stability and accept psychological counseling and support. Especially for couples who have not been pregnant for a long time, they may have psychological problems such as depression, anxiety and depression, so they need professional psychological support.
summary
IVF is a complex technology, which requires strict screening and evaluation to ensure the health of couples and the prediction of effects. The conditions of women and men, genetic diseases and psychological factors are all important factors affecting the success rate and risk of IVF. Therefore, before deciding whether to carry out IVF, couples should carefully assess their own conditions and risks, consult and discuss with professional doctors in detail, and make wise decisions.
