Which people are suitable for IVF frozen embryos and blastocysts?
IVF technology is a kind of assisted reproductive technology, which is applicable to some couples who cannot conceive naturally. In vitro frozen embryos and blastocysts are one of the important ways. The following is a detailed description of the population applicable to IVF frozen embryos and blastocysts from four aspects: women's age, oviduct problems, male factors and genetic disease screening.
Age of women
The fertility of women gradually decreases with age, especially after the age of 35, the difficulty of pregnancy increases significantly. Therefore, for older women, IVF and blastocyst technology is an effective choice. This is because in the process of IVF, multiple fertilized eggs can be cultured to the blastocyst stage, and high-quality embryos can be selected for transfer to improve the pregnancy success rate. For older women, obtaining high-quality embryos is crucial for successful pregnancy.
In addition, for women who have failed in assisted reproduction for many times, frozen embryos and blastocysts of test tube babies can also be considered. Multiple failures may be due to some problems during embryo implantation, such as the endometrium is not suitable for implantation. Through the technology of frozen embryo and blastocyst, we can choose the right time point for implantation to improve the success rate.
Fallopian tube problems
The fallopian tube is an important part of the pregnancy process. Once the fallopian tube is abnormal, pregnancy will be affected. For women with oviduct problems, IVF frozen embryos and blastocysts are a good choice for assisted reproduction. Through IVF technology, the problem of fallopian tube can be bypassed, and the fertilized eggs can be directly transplanted into the uterus, thus improving the success rate of pregnancy.
Common fallopian tube problems include fallopian tube blockage, fallopian tube resection or ligation, etc. For couples unable to conceive naturally due to oviduct problems, IVF frozen embryos and blastocysts technology is a solution.
Male factors
Male factors are another important reason for couples' reproductive difficulties. Common male factors include low semen quality and insufficient sperm quantity. For these problems, IVF frozen embryo and blastocyst technology can also help.
Through IVF technology, high-quality sperm can be selected to combine with eggs to form high-quality embryos. Under the technology of frozen embryo and blastocyst, embryos can be screened and cultured better to improve the success rate of pregnancy. Therefore, for fertility problems caused by male factors, IVF frozen embryos and blastocysts are a feasible solution.
Genetic disease screening
For some couples carrying specific genetic disease genes, in order to avoid the transmission of diseases to the next generation, IVF frozen embryos and blastocysts are a feasible choice. In the process of IVF, embryo gene screening can be carried out to detect whether the embryo carries harmful genes. Through screening, healthy embryos can be screened for transplantation to reduce the risk of disease.
At the same time, gender selection can also be carried out. For some specific genetic diseases, such as chromosome abnormalities, the possibility of disease can be reduced by selecting gender. This is a useful assisted reproductive choice for couples with familial genetic diseases.
Summary
In vitro frozen embryos and blastocysts are suitable for older women, oviduct problems, male factors and genetic disease screening. For these couples, IVF technology can not only solve the fertility problem, but also improve the success rate of pregnancy and reduce the risk of genetic diseases. Therefore, this technology has been widely used in hospitals.
