Test tube baby is an assisted reproductive technology, and many people believe that test tube baby means they can conceive as many children as they want. Therefore, many people think that test tube baby is mostly twins, but it is known to be multiple births. In fact, in vitro fertilization does not mean that you can conceive several children just because you want to have a few children. If there are multiple pregnancies in IVF, it is necessary to reduce the number of children. Is there a high risk of reducing pregnancy in IVF?
What situations require tire reduction
1. Women who are naturally pregnant or have three or more pregnancies through assisted reproductive technology. Based on personal circumstances, it is recommended to reduce to single or twin births.
2. Prenatal diagnosis of fetuses with genetic disorders, chromosomal abnormalities, or structural abnormalities in multiple pregnancies.
3. Although women diagnosed with multiple pregnancies in the early stages need to have a reduction in pregnancy, if one spouse has chromosomal abnormalities, a history of congenital birth defects, or the pregnant woman is of advanced age, the pregnancy can be kept until mid pregnancy, and then a reduction can be chosen based on the prenatal diagnosis results.
4. Women with multiple pregnancies such as elderly pregnant women, scarred uterus, uterine malformation, and cervical dysfunction.
5. Pregnant women with other diseases, such as hypertension, diabetes, etc.
There are also related risks associated with fetal reduction surgery
The biggest drawback of fetal reduction surgery is that it can sometimes lead to the miscarriage of the remaining fetus and the possibility of premature birth in newborns.
For women, postoperative bleeding, infection, and other situations may occur.
But relatively speaking, this can already be considered a relatively safe way. Because for multiple pregnancies, especially those with three or more pregnancies, the likelihood of premature birth can reach almost 100%, and there are some other serious complications.
Although the implementation of fetal reduction surgery needs to be determined based on the specific clinical situation and the specific requirements of women.
However, for the implementation of fetal reduction surgery in the early, middle, and late stages of pregnancy, overall, the incidence of postoperative complications (such as miscarriage rate) is similar. For multiple pregnancies with four or more fetuses, it is still recommended to undergo early fetal reduction.
The above has discussed under what circumstances it is necessary to reduce the number of fetuses in IVF, as well as the risks of IVF reduction surgery. As a woman who hopes to conceive a baby through assisted reproductive technology such as in vitro fertilization, you must be aware that multiple or twin pregnancies through in vitro fertilization require fetal reduction, which also carries certain risks.
