Test tube baby dragon and phoenix: four aspects of assistive technology
Test tube baby is a method to help infertile couples achieve fertility through artificial assistant technology. In this process, a variety of auxiliary technologies have been applied and developed to improve the success rate of pregnancy. This article will introduce the main assistive technologies used in IVF from four aspects.
Aspect 1: In vitro fertilization technology
In vitro fertilization (IVF) is the most common IVF assisted technology. First, women receive hormone therapy to promote the development of polycystic ovaries, and the eggs are extracted after maturity. Next, obtain a male semen sample, and use certain laboratory procedures to combine sperm with eggs. After that, the embryos were cultured in the laboratory for a few days and then transplanted into the uterus of a woman. In vitro fertilization (IVF) has been widely used with a high success rate, and has become a routine operation in many fertility centers and hospitals.
The auxiliary technology of IVF also includes intracytoplasmic sperm injection (ICSI). ICSI can solve the problem of sperm quantity or quality caused by male factors. Through the operation under the microscope, single sperm is injected into the egg cell, which can improve the chance of successful pregnancy even if the sperm quality is poor.
In addition, there are also more advanced technologies, such as the blastocyst transfer, which delays the cultured embryos to be transferred to the uterus on the fifth or sixth day, thus increasing the chance of obtaining pregnancy.
Aspect 2: Embryo screening technology
In the process of in vitro fertilization, in addition to conventional embryo culture, embryo screening technology is also constantly developing to improve the success rate of pregnancy. Embryo screening technology aims to detect genetic diseases, chromosomal abnormalities and the potential development of embryos. The proportion of healthy embryos can be increased by removing abnormal embryos.
At present, embryo screening technology mainly has two methods: one is based on genetic diagnosis of embryonic cells, and the other is based on biochemical indicators in the process of embryo culture. The former involves obtaining cells from embryonic cells and conducting gene testing to exclude embryos carrying genetic diseases. The latter assesses the developmental ability of the embryo by monitoring specific substances in the embryo culture medium. The continuous development and improvement of these technologies have greatly improved the success rate of IVF.
Aspect 3: frozen embryo technology
Frozen embryo technology is another important auxiliary technology of in vitro fertilization. Excess embryos generated during in vitro fertilization can be frozen for subsequent cycles of transplantation. Cryopreservation of embryos can provide couples with more IVF cycle choices, reduce the need for multiple rounds of egg retrieval, and improve the pregnancy success rate.
At present, the freezing technology is very mature and relatively simple to implement. After being treated with protective additives, embryos are frozen in liquid nitrogen. When it is desired to use frozen embryos for transplantation, the embryos are thawed and revitalized in the laboratory. The application of frozen embryo technology plays a vital role in the development and progress of IVF.
Aspect 4: Auxiliary inoculation technology
The success of IVF depends not only on in vitro fertilization and embryo transfer, but also on the use of assisted pregnancy technology to provide support. Assisted pregnancy techniques mainly include hormone therapy, ovarian stimulation and endometrial preparation. These technologies help to adjust the female endocrine environment, promote ovarian development, and provide a suitable implantation environment for embryos.
The use of hormone therapy and other assisted pregnancy technologies requires strict monitoring and adjustment by doctors to ensure the safety and effectiveness of treatment. Choosing the right technology at the right time can greatly improve the success rate of IVF.
summary
Assisted technology is an important support for the birth of IVF. In vitro fertilization, embryo screening, frozen embryos and assisted pregnancy are constantly developing and improving, providing hope for couples who are eager to have healthy babies. Through the continuous innovation and application of these assistive technologies, the success rate of IVF will continue to increase, and it is possible for more couples to realize the dream of a complete family.
