Progress in IVF technology
IVF technology is a kind of assisted reproductive technology, which helps infertile couples realize their reproductive dreams through in vitro fertilization and embryo transfer. With the progress of science and technology, IVF technology has been continuously developed and improved, and now there are many technologies to help infertile couples achieve their reproductive aspirations.
1. In vitro fertilization technology
In vitro fertilization (IVF) is one of the most common IVF technologies. This technique combines female eggs with male sperm in the laboratory to form a fertilized egg. Then, after culture and development, healthy embryos will be selected and transplanted into the mother's uterus. In vitro fertilization (IVF) is widely used in a variety of infertility symptoms, such as fallopian tube blockage, polycystic ovary syndrome, etc. It can stimulate female ovaries to ovulate or directly obtain eggs from female bodies, and then combine with male sperm to form fertilized eggs.
IVF technology not only includes conventional IVF methods, but also includes "transfer of fertilized embryos from culture to blastocyst stage" and "indirect fertilization" and other methods. With the development of technology, in vitro fertilization (IVF) has become one of the commonly used treatments for infertile couples around the world.
2. Frozen embryo technology
Frozen embryo technology is a method of freezing unused healthy embryos. During in vitro fertilization, sometimes multiple healthy embryos will be obtained. Embryos that do not need to be transferred immediately can be frozen and stored until an appropriate time for transfer. This technology helps to reduce the stimulation of women's ovaries and the use of drugs, and can also improve the success rate.
Frozen embryo technology can also be used to continue expanding families. If infertile couples have successfully obtained one or more healthy embryos through in vitro fertilization, they can choose to freeze unused embryos for future pregnancy.
The development of frozen embryo technology has also solved a series of problems such as female hormone fluctuations, reduced the risk of manual control, and improved the success rate and safety of IVF technology.
3. Sperm and egg donation technology
For some infertile couples, they may not be able to provide their own eggs or sperm for in vitro fertilization. In this case, sperm and egg donation technology can help them achieve their reproductive aspirations.
Sperm donation refers to in vitro fertilization through the sperm provided by the donor. The donated sperm will combine with the female egg to form a fertilized egg, which will then be transplanted into the mother's uterus. Similarly, egg donation refers to in vitro fertilization through eggs provided by donors.
Sperm and egg donation technology helps infertile couples achieve their fertility aspirations by solving the problem of poor quality of their own eggs or sperm. This technology requires professional hospitals and strict matching procedures.
4. Parental embryo screening
Parental embryo screening is to screen whether there is genetic disease risk in fertilized eggs through genetic technology. By extracting cells from embryos, scientists can conduct gene testing to determine whether embryos carry harmful genetic material. If there are risks, doctors can choose to transplant safe embryos into the mother's uterus to reduce the incidence of genetic diseases.
Two parent embryo screening technology can help infertile couples reduce the risk of having sick children and bring peace and health to family life.
summary
With the progress of science and technology, IVF technology has been developing and improving. In vitro fertilization, frozen embryo technology, sperm and egg donation technology and parental embryo screening technology are all important technologies to help infertile couples realize their reproductive dreams. These technologies have been widely used in hospitals, improving the fertility success rate of infertile couples, and bringing them new hope and happiness.
