Posted by Dr. Doctor To Minh Huong – Head of Reproductive Support Department, Vinmec Times City International General HospitalMethods to evaluate immune disorders in the lining of the uterus and specialized regimens are giving hope to mothers who have failed embryo transfer during IVF. This is the first method performed in Vietnam, performed by doctors of Vinmec Fertility Center.
1. What is the “Local Immune Disorder” method?
The baby developing in the mother's womb is considered a miracle of nature. The formation of an embryo, a tiny living being from the mother's egg and father's sperm is considered the first miracle. Next, the embryo moves to the uterus, implants and grows. Uterine implantation is the second miracle of nature. Despite being a strange individual with the father's genetics, the mother's womb is ready to receive and nurture without rejection like the rejection of grafts like in cases of organ transplants (kidneys, livers).
The most amazing thing is that in women who have to ask for eggs, ask for embryos to be able to become mothers, the embryos - these living germs are completely foreign to the mother's womb, but are still received in harmony with the mother through Immune System.
However, the mother's ability to accept embryos depends on the local immune regulation of the uterine lining - through the action of immune factors such as natural killer cells, lymphocytes and cytokines.

2. Efficacy of topical immunotherapy
Local immune dysfunction is one of the causes of nest failure. Therefore, the diagnosis of these immunological disorders based on the analysis of immunological factors in the biopsied uterine lining will provide a solution to the problem of repeated embryo transfer failures. From 2016 to now, Vinmec Fertility Center has conducted research on local immune disorders on 100 cases of embryo transfer that failed on average 4 times. Research results show that, 72% of cases have local immune disorders. When an immune disorder is diagnosed and a specific regimen is applied, the clinical pregnancy rate (with fetal heart rate) in subsequent embryo transfers has increased to 52.2%. This is new hope for infertile couples. Up to now, with the continuous updating and application of advanced treatment methods, Vinmec Fertility Center is the first center in Vietnam to diagnose this pathology and build the center to become the first center in Vietnam. spearhead center in the field of infertility and improving implantation of the fetus.

Natural cycle monitoring: Your doctor will watch to make sure your biopsy is in the middle of the luteal phase. Preparation of the lining of the uterus with the use of hormonal drugs: You will be given the hormone oestrogen until an ultrasound scan of the lining of the uterus has an appropriate thickness. Then you are given more Progesteron. Biopsy to take samples for testing will be done after taking Progesteron for about 5 - 6 days, usually day 21 - 24 of the menstrual cycle. The endometrial biopsy will be done at the hospital or in combination with hysteroscopy.
