The birth mode of test tube baby dragon and phoenix fetus
Test tube twins are a pair of male and female twins born from the simultaneous development of multiple embryos in the process of in vitro culture through artificial assisted reproduction technology. Next, we will introduce the birth mode of test tube baby dragon and phoenix foetus from four aspects: embryo segmentation, embryo transfer, natural cycle and frozen embryo transfer.
1. Embryo segmentation
Embryo segmentation is an advanced assisted reproductive technology. Usually, the fertilized egg is taken out during in vitro fertilization, and then it is divided into two independent embryos. This method can stimulate the proliferation of early embryonic cells to produce twins. After segmentation, each embryo will continue to undergo in vitro culture and other necessary steps to ensure their growth and development.
The common methods of embryo segmentation are mononuclear embryo segmentation and two cell embryo segmentation. Mononuclear embryo segmentation is to divide the only nucleus of an early embryo into two new nuclei, so that each new embryo has the same genetic gene. Two cell embryo segmentation is to divide two cells of an early embryo into two new embryos.
Embryo segmentation method can increase the success rate of IVF birth, and also make the birth of twins possible.
2. Embryo transfer
Embryo transfer is one of the core steps of IVF, which determines whether the embryo can be successfully implanted and developed. Embryo transfer can be carried out in many ways, including in vitro fertilization transfer (IVF), egg transfer and embryo transfer back.
In vitro fertilization (IVF) is one of the common birth methods of twins. In this process, female eggs and male sperm combine in the laboratory to form an embryo. Then, the embryo will be cultured in vitro for a period of time to ensure its healthy and normal development. Next, doctors will select high-quality embryos for transplantation, hoping that they can successfully implant and grow.
Another common method is egg transplantation. In egg transplantation, doctors will collect eggs from a woman's ovary, then combine them with men's sperm, and culture embryos in the laboratory* Later, the embryo will be transferred back to the uterus of another woman in the hope of successful implantation and development into a dragon and phoenix fetus.
3. Natural cycle
The natural cycle of IVF refers to the process in which women successfully conceive through natural ovulation and artificial assisted pregnancy technology during the ovulation cycle. This method does not require the use of hormone drugs to stimulate ovarian ovulation, reducing some discomfort and risk.
In the natural cycle, the doctor will determine the ovulation time according to the women's menstrual cycle, and during this period, artificial insemination will be carried out. Female eggs and male sperm combine in the laboratory to form an embryo. Next, doctors will choose * high-quality embryos for transplantation.
The use of natural cycles for IVF is a relatively natural way, which can reduce the intervention on women's bodies, and also has a certain success rate.
4. Frozen embryo transfer
Frozen embryo transfer refers to the freezing and preservation of the remaining healthy embryos in the process of in vitro fertilization, and the transfer when needed. This way can reduce the intervention on women's bodies and improve the success rate of IVF birth.
In the process of frozen embryo transfer, female endometrium needs to be prepared for embryo implantation through hormone therapy. The frozen embryo is then thawed and implanted into the female endometrium. Later, it is hoped that the embryo can be successfully implanted and developed into a dragon and phoenix embryo.
summary
The birth methods of test tube baby dragon and phoenix fetuses include embryo segmentation, embryo transfer, natural cycle and frozen embryo transfer. The application of these technologies can increase the success rate of test tube baby twins, help more families realize their reproductive dreams, and also provide a variety of options and ways to produce healthy twins.
