What are the signs of blastocyst biochemistry?

In vitro fertilization is a relatively high-tech method of assisting pregnancy, which has fulfilled the dreams of many infertile couples to have children. However, it is also easy for embryos to have biochemical pregnancies after IVF, so you must pay attention to some of the symptoms that embryos may show. Only by discovering them in time and taking some measures in time can you reduce the harm as much as possible.

1. Symptoms of biochemical in vitro fertilization 1. No gestational sac can be seen in the uterus by B-ultrasound. 2. A very low blood HCG value only means that you are pregnant, but it cannot indicate whether implantation is successful. 3. Generally, spontaneous abortion will occur within 50 days. A grayish-white film will flow out.

2. Causes of biochemical failure in IVF 1. Biochemical failure in IVF refers to the phenomenon that after embryo transplantation, the embryo fails to implant or stops developing, leading to miscarriage. Generally, the embryo will implant within 3-7 days after test tube transfer, and pregnancy can be detected about 10-14 days after transfer. However, if the patient cannot detect a positive result with the test strip and there is vaginal bleeding, it is likely to be a biochemical pregnancy. 2. Clinically, the main reason for biochemical in vitro fertilization is the chromosomal abnormality of the patient couple, which will lead to poor embryo quality, difficulty in embryo implantation, or miscarriage after embryo implantation. If a patient experiences multiple IVF biochemical phenomena, the specific cause should be investigated first, and then appropriate measures should be taken for targeted treatment. 3. Suggestions: Adjust your lifestyle, eat more vegetables and fruits, drink more water, eat less spicy food, prevent colds, increase nutrition, balance nutrition, take more vitamin foods, and supplement appropriate amounts of trace elements such as zinc, magnesium, iron, calcium, etc. If you have gynecological inflammation, you should get timely treatment.

3. How to prevent biochemical miscarriage with in vitro fertilization 1. Use contraception within six months after a miscarriage, and wait six months before getting pregnant again to reduce the occurrence of miscarriage. 2. To undergo genetic testing, both husband and wife should undergo chromosome testing at the same time. 3. Do blood typing, including Rh blood typing. 4. If the internal os of the uterus is loose, internal os suture can be performed. 5. The use time of drugs for the treatment of corpus luteum insufficiency must exceed the pregnancy period of the last miscarriage. For example, if the last miscarriage was in the third month of pregnancy, the treatment time must not be less than 3 months from the beginning of pregnancy. 6. For patients with hypothyroidism, you should wait until your thyroid function returns to normal before getting pregnant, and you should also take anti-hypothyroidism drugs during pregnancy.
