Method of IVF
Test tube baby is a kind of assisted reproductive technology. It combines the sperm and eggs of both men and women in test tubes, then cultivates embryos in an appropriate environment, and finally transfers healthy embryos into the mother to achieve the purpose of fetal development and pregnancy. The development of IVF technology has provided the possibility of hope for infertile couples. The methods of IVF will be described in detail from four aspects.
In vitro fertilization
In vitro fertilization (IVF) is one of the most important methods for IVF. This method is to put female eggs and male sperm into a culture dish and conduct IVF in an appropriate medium. First, women need to be treated with ovulation promoting drugs to stimulate the development and excretion of eggs. Then, doctors use special collection methods to extract eggs from women's ovaries. Next, sperm and egg are combined by a method called "short-term sperm egg combination". Finally, the cultured embryos are transferred into the mother's uterus in the hope of a successful pregnancy.
In vitro fertilization (IVF) is one of the most common methods in IVF technology, which is applicable to a variety of infertility causes. It provides hope for infertile couples, but it does not always succeed. The success rate is affected by many factors, including age, health status and other fertility factors.
Egg donation
Egg donation is a test tube baby method, which is suitable for women with premature ovarian failure or inability to lay eggs. In this method, women receive eggs from donors for in vitro fertilization and embryo transfer. The egg donation process involves screening and testing qualified donors, collecting the donor's eggs, combining the donor's eggs with the man's sperm, and then transplanting healthy embryos into the uterus of the woman receiving the egg donation.
Egg donation is a test tube baby method with high success rate, but it needs strict matching and monitoring process. For some women who cannot lay eggs, egg donation is the only way to achieve fertility.
embryo freeze
Embryo freezing is a method of IVF to preserve healthy embryos in a low temperature environment. After in vitro fertilization, if there are multiple healthy embryos, you can choose to freeze some of them for future use. Frozen embryos can be transferred in the future to improve the success rate of IVF.
Embryo freezing not only helps to increase the success rate of IVF, but also provides more time and options for infertile couples. Frozen embryos can be used when needed, avoiding frequent egg retrieval and fertilization processes. At the same time, embryo freezing also helps to avoid the risk of multiple pregnancies.
Monitoring and screening of embryo maturation
IVF technology also includes the monitoring and screening of embryos. In the process of in vitro fertilization and embryo culture, doctors will regularly check the development of the embryo. By observing the cell number, cell arrangement, chromosome number and other characteristics of the embryo, the quality of the embryo can be evaluated, so as to select the most likely successful embryo for transplantation.
The monitoring and screening of embryo maturation provides a better choice and possibility for infertile couples. By selecting the best quality embryos for transplantation, the success rate of pregnancy can be improved and the risk of multiple pregnancy can be reduced.
Summary
As an assisted reproductive technology, IVF provides the possibility of fertility for infertile couples. Common IVF methods include in vitro fertilization, egg donation, embryo freezing, and monitoring and screening of embryo maturation. These methods have different application ranges and success rates in different situations. By choosing suitable methods and hospitals, infertile couples are expected to achieve their dreams of childbearing.
