Can a blastocyst in IVF transfer into twins? In daily life, there is always a lot of curiosity about twins, thinking that they are very novel. However, the probability of twins is very low compared to single births, and even in vitro fertilization, it is difficult to ensure that they are definitely twins. So, is it possible for transplanting a single blastocyst to become twins?

Can a blastocyst in IVF transfer into twins?

Not all twins are developed from two independent embryos. Among them, 30% of twins are monozygotic, meaning they are derived from the division of an embryo. So it is possible to have twins by transplanting an embryo, but the probability is low.

2. If embryo division is detected after embryo transfer, it is necessary to identify the chorionic villi of the embryo between 11 weeks and 13 weeks plus 6 days to determine whether it is a single cashmere sheep, double cashmere sheep, or a single cashmere sheep or conjoined fetus. It is necessary to understand potential problems in advance and take scientific measures to ensure the health of the mother and fetus as much as possible.

3. Some embryos may experience developmental abnormalities after division, which may affect their continued pregnancy, so not all embryos can become twins after division. Everyone should have a correct understanding of various situations during pregnancy and be fully prepared mentally.

What happens to embryo division after transplantation?

1. Double cashmere twin sheep: If twin sheep have better pregnancy and delivery outcomes, twin transfusion syndrome will rarely occur.

3. Single cashmere twin sheep: Single cashmere twin sheep need to monitor fetal ultrasound twice before pregnancy to observe the fetal blood transfusion system, in order to detect twin transfusion syndrome in a timely manner and provide timely treatment and intervention.

4. Single cashmere, single sheep, and twins: Two babies live together in the same amniotic cavity, which can easily cause umbilical cord entanglement and lead to fetal death.

The situation of conjoined children cannot be ignored. If unfortunately discovered, it is necessary to decide whether to terminate the pregnancy based on the opinions of the family.

Can a blastocyst in IVF transfer into twins? Although the probability of giving birth to twins from a single embryo during in vitro fertilization is very low, it is not necessary to blindly request the transfer of two or more embryos in order to give birth to twins, as there are clear regulations on the number of embryos to be transferred, and everyone must comply with the regulations. The risk of multiple pregnancies is higher than that of single pregnancies, so do not blindly pursue them.
