Is there a high risk of premature birth in IVF?
In vitro fertilization (IVF) is a kind of assisted reproductive technology, which helps couples with fertility disorders realize their reproductive dreams through in vitro fertilization, embryo transfer and other processes. However, it has been controversial whether IVF has a higher risk of preterm birth than natural pregnancy. This article will elaborate on this issue from many aspects.
1. Multiple pregnancy
An important factor in IVF pregnancy is the high incidence of multiple pregnancy. In order to improve the success rate of pregnancy, multiple embryos are usually implanted into the uterus during IVF. Although this can increase the chance of a successful pregnancy, it also increases the risk of premature delivery. The risk of multiple pregnancy to pregnant women and fetuses is high, which is easy to lead to premature delivery, low birth weight and other complications.
Preterm birth has a great impact on the development of infants, especially infants born prematurely may have immature respiratory system, nervous system and immune system, increasing the risk of diseases and complications.
2. Maternal age
IVF is usually carried out by older women, because age is an important factor affecting fertility. However, older pregnant women are more prone to complications and premature delivery. According to the study, pregnant women over 35 years old are more than twice as likely to suffer from premature delivery as young women.
Because of their older age, IVF women may easily suffer from some chronic diseases, such as hypertension and diabetes, which will also increase the risk of premature delivery.
3. Chronic diseases before pregnancy
For women with some chronic diseases before pregnancy, such as polycystic ovary syndrome (PCOS) and endometriosis, IVF will also increase the risk of premature delivery. These diseases may be related to female fertility degradation and infertility. After IVF, the risk of complications during pregnancy and premature delivery may increase due to the existence of previous diseases.
In addition, IVF may need to use hormone and other auxiliary measures to promote pregnancy and pregnancy progress, and the use of these hormones may also increase the risk of premature delivery.
4. Experience of hospitals and professional teams
The technical level and processing ability of different hospitals and professional teams on IVF will also affect the risk of premature delivery. There are some internationally renowned IVF hospitals with rich experience in the field of reproductive medicine, complete professional teams and high levels of assisted reproductive technology. These hospitals and teams can usually better control the risk of preterm birth, provide follow-up management and support, and thus reduce the incidence of preterm birth.
In conclusion, the risk of preterm birth of IVF does increase compared with natural pregnancy. Multiple pregnancy, women's age, chronic diseases before pregnancy, and the experience of hospitals and professional teams are all factors that affect the risk of premature delivery. However, after selecting appropriate hospitals and professional teams, and receiving careful management and care, the risk of preterm birth can be effectively controlled to improve the safety and success rate of IVF.
