Whether or not the growth and development of the embryo will be affected by a woman’s manifestation of fire after an IVF transfer depends on the patient’s specific condition. The term “fire” is used in Chinese medicine, which corresponds to inflammation caused by bacterial, viral or microbial infections in Western medicine. If the patient is an inflammation of the reproductive tract, the impact on pregnancy is relatively large and needs to be actively treated. Simple inflammation of the vulva and vagina will not affect the embryo if treated actively, but if it is not treated in time and causes an infection, it may lead to miscarriage. Other parts of the limited inflammation does not cause systemic infection, the embryo is not affected, such as the patient appears, nasal congestion, runny nose, sore throat and other upper respiratory tract infections, frequent urination, urinary urgency, urinary pain and other urinary tract infections. If the inflammation subsides after active treatment, the embryo will not be affected, but if the inflammation is not treated in time, causing the local spread of inflammation or systemic infection, causing clinical symptoms of fever, the fetus will be affected.
