The success rate of transferring two fresh embryos is related to the quality of the fresh embryos. Since IVF technology is now more mature, the success rate of transferring two fresh embryos is higher if the pregnant woman’s health is better, her age is younger, and the quality of the two fresh embryos transferred at the same time is better. However, if the quality of the fresh embryos is not good or the pregnant woman’s health condition is poor, the success rate of the transfer will be reduced accordingly. At present, it is not recommended to transfer two fresh embryos at the same time. Although transferring two embryos at the same time can increase the probability of successful pregnancy, if both of them are successful, multiple pregnancies will cause great damage to the pregnant woman’s body, and at the same time, it will be easy to miscarry and preterm labor, which is hazardous to the health of both the pregnant woman and the fetus. It is recommended that the patient should consult the doctor in time and choose the number of fresh embryos to be transferred under the doctor’s guidance.
