Is it possible that IVF babies are due too early?
In vitro fertilization (IVF) refers to the transfer of fertilized eggs into the mother's uterus to breed babies. Although the success rate of IVF is getting higher and higher, it is still a matter of concern whether the expected date of delivery is too early. This article will discuss the possibility of premature delivery of IVF from the aspects of gestational age, transplant time, medical conditions and maternal and infant health.
Gestational age
The expected date of IVF is related to the pregnant age of the mother. Older women may face greater risk of pregnancy complications, such as premature delivery, low birth weight, etc. Scientific research shows that women over the age of 35 have an increased risk of pregnancy, so the IVF babies of these pregnant women may be expected to be born earlier than normal.
In addition, young women may also face the problem of prematurity. If women receive purification therapy or other treatments that affect the reproductive system at puberty, their ovarian function may be affected, leading to premature aging. In this case, the expected date of IVF may also be too early.
It should be pointed out that although age is an important factor, not all older or younger pregnant women will have a premature expected date of birth. The expected date of delivery still depends on individual differences and other factors.
Migration time
The success of IVF is related to the quality of embryo and the time of transfer. During IVF of IVF babies, doctors will monitor the development of embryos and choose the most appropriate time to transfer the embryos into the mother's uterus. If doctors choose to transfer embryos at an early stage of embryonic development, the expected date of IVF may be earlier.
In addition, if the embryo of IVF is multiple (including twins and triplets, etc.), it may be necessary to transfer multiple embryos at the early stage of embryonic development. Multiple pregnancy often increases the risk of premature delivery, so some hospitals will choose to transfer a single embryo when the embryo development is slightly advanced to reduce the risk of premature delivery.
Medical conditions
The equipment, technology and experience of different medical institutions may also affect the expected delivery date of IVF. In areas where resources are scarce, medical conditions may be limited and the most advanced equipment and technical support cannot be provided, which may lead to deviation in the expected delivery date of IVF. In some hospitals with advanced medical equipment and professional teams, the expected date of IVF is closer to the normal pregnancy period.
In addition, the experience and professional level of the medical team are also important factors. Some hospitals may lack professionals in the field of IVF, resulting in unskilled operation and affecting the accuracy of the expected delivery date. Therefore, it is very important to choose experienced hospitals and doctors.
Maternal and infant health
Maternal and infant health may also have an impact on the expected delivery date of IVF. If pregnant women have complications during pregnancy, such as pregnancy hypertension, diabetes, etc., it may lead to premature delivery. Maternal health problems may lead to fetal growth restriction or uterine dysfunction, which may affect the expected delivery date of IVF.
At the same time, IVF may also have some risk factors related to premature delivery, such as abnormal fetal position, placental insufficiency, etc. These factors may lead to the early delivery of IVF.
summary
The possible premature delivery of IVF is related to the gestational age, transplant time, medical conditions and maternal and infant health to some extent. Older or younger pregnant women, early embryo transfer, insufficient hospital equipment and professional level, as well as maternal and infant health problems may lead to the early delivery of IVF. However, the determination of the expected date of birth also depends on individual differences and other factors, so the expected date of each test tube baby may have some uncertainty.
