1. embryo frozen for a long time can still be used?
Du Hongzi: theoretically, embryo frozen can be frozen indefinitely in liquid nitrogen. 1 years and 10 years and 20 years are the same. Survival after embryo resuscitation has nothing to do with preservation time. However, technology has been improving. More than ten years ago, cryopreserved embryos were made by slow freezing technology, which is now vitrified. Therefore, the current freezing technology will increase the survival rate of embryos. Will the freezing of
2. damage the embryo?
Du Hongzi: any embryo operation can cause damage. The freezing process is the same. But the injured embryo may not survive due to freezing damage. "Just like human immunity, there are high and low points. If the living environment is poor, people with poor immunity will increase their chances of getting sick or dying." Can
3. embryos be able to conceive after being thawed as fresh embryos?
Du Hongzi: for embryos themselves, the embryos that are still alive after thawing are the same as fresh embryos. In theory, the successful rate of thawing embryo transfer is higher than that in the uterine environment that is not suitable for fresh embryo transfer during the period of frozen embryo transfer. Is
4. the same thing for babies born with frozen embryos and those born with new embryos?
Du Hongzi: according to the current data, the frozen embryo tube baby born after the frozen embryo transfer is healthy and is not different from the fresh embryo.
5. is a good embryo that is frozen when young, or is it a new embryo that is acquired at an advanced age?
6. who can cryopreservation embryos in hospitals?
Du Hongzi: the embryo can be frozen in the hospital. There are three main cases: one is the husband and wife who is in accordance with the condition of the test tube baby. After the operation of the test tube baby, the remaining good quality embryos can be frozen. The main purpose is that if the embryo transfer is not successful, the frozen embryo will be retransplanted in the next cycle. Or, when they need to reproduce again, they can also be used. Two, some women, due to hormonal abnormalities, endometrial factors and other reasons, are not suitable for embryo transfer immediately after the ovulation cycle, and embryos can also be cryopreserved. In this way, the use of embryos can be improved, and the complications caused by ovulation and oocyte retrieval can be reduced. Three, it can be used as a way for infertile couples to preserve fertility.
