Is there a high probability of multiple births in IVF? Is there a high probability of twins in IVF? A study in the United States once found that the proportion of multiple births in the United States has almost doubled over the past 40 years. The main reason for this situation is related to the use of artificial assisted reproductive technologies such as in vitro fertilization. Overall, 20 out of every 100 multiple births in the United States are in vitro fertilization. So is there a high probability of multiple births in IVF babies?

There are relevant studies indicating that the difference between the laboratory environment and the human environment may be a reason for the occurrence of more twins.

In the case of natural conception, only about three pairs of twins appear in every 1000 deliveries. However, with the help of in vitro fertilization technology, nearly 12 pairs of twins appear in every 1000 deliveries.

Experts have pointed out that the proportion of twins naturally conceived by pregnant women is usually 0.8% -1%, but the proportion of triplets is even less than 1/100000.

But for in vitro fertilization, due to relevant regulations of the Ministry of Health, a maximum of 2 embryos can be transferred for the first transfer under the age of 35, and a maximum of 3 embryos can be transferred for the first transfer over the age of 35. It is precisely for this reason that the probability of multiple pregnancies in IVF is much higher than in natural pregnancy.

Compared to couples who are normally pregnant, the probability of twins being successful is much higher. Therefore, couples who want twins will choose this technology. However, multiple pregnancies in IVF must be reduced. This is for the health of pregnant women, so having a child is the best choice. Multiple pregnancies can easily lead to serious complications and endanger the safety of the mother and baby, such as miscarriage, premature birth, fetal malformations, gestational hypertension and polyhydramnios, abnormal fetal position, delayed fetal development, postpartum hemorrhage, etc. Therefore, having an only child is the safest choice.

In addition, the Ministry of Health also has clear regulations to reduce the number of triplets and above, as it feels that triplets are not allowed to be born. To be precise, even with IVF technology, it can only be twins at most.

Is there a high probability of multiple births in IVF? The probability is a bit higher, but the Ministry of Health also has clear regulations that even through IVF technology, the number of triplets and above must be reduced, so couples still need to consider it carefully.
