Is IVF often premature?
IVF refers to the babies produced by in vitro fertilization (IVF) or other artificial pregnancy technology. In the past decades, the technology of IVF has been applied and developed on a large scale. However, compared with natural pregnancy, whether IVF will often give birth prematurely remains a concern.
Risk of preterm birth in test tube infants
Preterm delivery refers to the birth of a baby when the pregnancy period is less than 37 weeks. According to research data, the incidence of preterm birth is relatively high among IVF infants. The risk of preterm birth in IVF may be influenced by several factors.
First, the incidence of IVF multiple pregnancy is higher than that of natural pregnancy. Because IVF embryos can be cultured in vitro, doctors usually implant multiple embryos into the uterus to increase the probability of successful pregnancy. However, multiple pregnancies increase the risk of premature delivery.
Secondly, hormone therapy used in IVF may also increase the risk of premature delivery. Hormone therapy is widely used in IVF to promote ovulation of ovary and preparation of endometrium. However, these hormones may cause the uterine muscles to contract excessively, which may lead to premature delivery.
In addition, IVF women may receive more medical monitoring and intervention during the whole pregnancy process. This includes regular ultrasound, blood tests and other examinations. These monitoring and intervention may lead to early detection and treatment of maternal and infant health problems, thus early termination of pregnancy, leading to premature delivery.
Reducing the risk of premature birth in IVF
Although the risk of IVF preterm birth is relatively high, doctors have taken some measures to reduce the incidence of preterm birth.
First, doctors will try to avoid multiple pregnancies. According to the patient's condition and age, the doctor will assess the risk of implanting multiple embryos, and determine the number of implants according to the individualized situation. By controlling the number of embryos in the uterus, the incidence of multiple pregnancy and preterm birth can be reduced.
Secondly, doctors will adjust hormone treatment plan accurately. Through rational medication and precise control of hormone levels, the risk of uterine muscle over contraction can be reduced, thus reducing the incidence of premature delivery.
In addition, doctors will carry out strict monitoring and management, including regular inspection and timely treatment of potential maternal and infant health problems. In the case of early detection and active treatment of any health problem, it can reduce the need for early termination of pregnancy, thereby reducing the incidence of premature delivery.
summary
In general, compared with natural pregnancy, IVF has a higher risk of premature delivery. Multiple pregnancy, hormone therapy and medical monitoring may be the potential causes of premature delivery. However, doctors have effectively reduced the risk of preterm birth of IVF by limiting multiple pregnancies, adjusting hormone therapy and strict monitoring and management. For IVF couples, they need to work closely with the doctor, follow the doctor's advice, and actively take necessary measures to reduce the risk of premature delivery and improve the healthy birth rate of children.
