Methods of controlling the male female ratio of test tube infants in Guangzhou
With the progress of science and technology, more and more couples choose IVF technology to realize their dream of having a healthy baby. However, the male female ratio of IVF has always been concerned. In order to avoid the imbalance between men and women, some hospitals in Guangzhou have adopted some control methods. In this article, we will elaborate on the control methods of the ratio of male to female test tube babies in Guangzhou from the perspectives of reducing male embryo selection, sperm separation technology, embryo saliva sex detection and objective consultation.
Reduce male embryo selection
Some IVF hospitals in Guangzhou restrict the selection of male embryos. They encourage couples to choose female embryos to balance the male female ratio. This can be done by selecting methods for female embryos, such as single nucleotide polymorphism analysis, embryo activity index score, etc. These methods are based on the gene activity level of the embryo, help doctors predict the sex of the embryo, and then provide couples with advice on selecting female embryos.
In addition, some hospitals in Guangzhou also reduce the selection of male embryos by providing couples with objective consultation on the relevant knowledge and risks of male embryos. They stressed that the selection of male embryos should be based on the health of the baby, rather than on personal preferences.
Sperm separation technology
In order to control the male female ratio of test tube babies in Guangzhou, some hospitals have adopted the technology of sperm separation. This technique uses centrifugation and fluorescence in situ hybridization to separate the X and Y chromosomes. Then, according to the needs of the couple, the sperm enriched with X chromosome or Y chromosome is selectively used for fertilization to achieve the purpose of regulating the proportion of male and female embryos.
Although this technology can help adjust the gender ratio, hospitals still emphasize that its application should be strictly restricted. They suggested that couples should conduct comprehensive consultation and understanding before choosing this technology, and fully consider its ethical and legal risks.
Sex detection of embryonic saliva
Some IVF hospitals in Guangzhou also use embryo saliva sex detection technology to help couples choose the baby's sex. Based on the genetic characteristics of the embryo, this technology can accurately predict the sex of the embryo by analyzing the DNA in saliva.
Embryo saliva sex detection technology has the advantages of non-invasive and high accuracy. It can help couples understand the sex of embryos before IVF transplantation, so that they can choose according to their own needs. However, the hospital also stressed that the use of this technology should follow ethical and legal norms to ensure its rational and sustainable application.
Objective consultation
In order to help couples make more intelligent choices, some IVF hospitals in Guangzhou provide objective consultation services. Their professional doctors will provide couples with relevant knowledge about IVF sex selection, including the principles, risks and limitations of technology. Through objective consultation, couples can understand the advantages and disadvantages of different choices, so that they can make better decisions.
Summary
In order to control the male female ratio of test tube babies in Guangzhou, some hospitals have adopted methods such as reducing male embryo selection, sperm separation technology, embryo saliva sex detection and objective consultation. These methods aim to balance the ratio of men and women, and provide a variety of choices for couples. However, hospitals also emphasize that these methods should be strictly restricted and standardized to ensure their rational and sustainable application.
