First of all, the word fetal preservation is not a medical concept, but a common name. From a medical point of view, as long as it is after ivy infant embryo transfer, we all need to give corpus luteal support, which can also be regarded as fetal preservation. After the patient's embryo transfer, it is necessary to use the drug according to the doctor's instructions, and there are several ways to administer progesterone, such as oral, intramuscular injection, plugging and so on.
In addition to luteal support, embryo transfers generally do not require special fetal protection. Because whether the embryo transfer can be successful depends on the quality of the embryo itself and whether the uterine environment is suitable for embryo implantation. If the embryo itself is defective, then it is not possible to save the fetus with medication, and there is no need to use medicine.
However, for some special patients, such as patients with recurrent miscarriages, it is difficult for embryo transfer to implant in such patients, or it is easy to have miscarriage after implantation, then it is not a simple luteal support can solve. Before the embryo transfer, it is necessary to find out the cause of the miscarriage, such as immunity, infection and even chromosomal problems. After embryo transfer, it is necessary to use drugs in a targeted manner to avoid or reduce the impact of these adverse factors on the embryo, so as to achieve the purpose of fetal preservation.
Therefore, whether or not fetal protection is required after embryo transfer varies from person to person, and not all patients need to protect the fetus.
