How to carry out embryo transfer after successful IVF
IVF is a method to help couples who cannot conceive naturally to realize their reproductive dreams through artificial assisted reproduction technology. After the embryo is successfully cultivated in the laboratory, the next step is to carry out embryo transfer. Embryo transfer is a complex and accurate process, which will be described in detail in the following four aspects: embryo selection, surgical preparation, surgical operation and post transplant care.
Embryonic selection
Embryo selection is an important part of IVF. In the selection process, doctors usually select the most suitable embryo from multiple embryos for transplantation. This process mainly depends on the quality assessment of embryos. The evaluation of embryos includes morphological evaluation and genetic evaluation.
Morphological evaluation is to judge the quality of the embryo by observing its morphology, cell number and division. Generally speaking, the quality is better if the number of cells is evenly distributed and the embryo develops well.
Genetic evaluation is to screen chromosome abnormalities and genetic diseases by detecting the chromosomes of embryos. This assessment can avoid the genetic risk of some genetic diseases and improve the health of embryos.
Generally, doctors will select the best quality embryos with negative genetic positive evaluation results for transplantation.
Surgical preparation
Before embryo transfer, a series of examinations and preparations are required. The first is to prepare the matrix. The mother needs to thicken the endometrium. Generally, estrogen is given for auxiliary thickening to ensure the proper thickness of the endometrium.
The second is to prepare the embryo. Embryos need to be thawed in the laboratory to ensure their integrity and viability.
In addition, an endoscopic examination is needed to ensure that there are no obvious abnormalities in the endometrium and to determine the best time for transplantation.
Operation
Embryo transfer is usually performed in a gynecological hospital or reproductive medical center. The operation is usually carried out in the gynaecological consulting room or operating room without pain.
First, the doctor will insert the thawed embryo into the uterine cavity through a thin tube and operate it under the guidance of hysteroscopy or B-ultrasound to ensure the correct positioning of the embryo.
Next, the doctor will fix the embryo to prevent it from falling off. Fixation is usually achieved by endometrium anchoring or embryo adhesive.
The whole operation process generally lasts for 10-20 minutes. The operation is well tolerated, and the patient can leave the hospital immediately after the operation.
Nursing after transplantation
The care after transplantation is very important, which can help the embryo to be well implanted and developed in the uterus. Patients need to follow the doctor's instructions to keep their bodies relaxed and avoid strenuous exercise and overwork.
In addition, patients should pay attention to diet conditioning, try to eat less greasy food and stimulating food, and eat more food rich in protein, vitamins and minerals, which will help to provide nutrition for embryonic development.
During the whole post transplantation cycle, patients also need to take regular reexaminations to observe the implantation and development of embryos, and adjust the drug delivery program in time to improve the success rate of IVF.
Summary
IVF embryo transfer is an accurate and complex operation, including embryo selection, surgical preparation, surgical operation and post transplant care. The evaluation and selection of embryos is an important link to ensure the success of transplantation. The preparation before the operation can ensure the smooth progress of the operation, and the postoperative care can help the embryo to be implanted well. Before embryo transfer, couples should understand the whole process in detail and follow the doctor's guidance and suggestions to improve the success rate of IVF.
