Sequelae and risk of IVF
1. Pregnancy complications
IVF technology is a complex medical process, which involves multiple operations and drug use, so it may increase the risk of complications for mothers during pregnancy. Some common complications include pregnancy induced hypertension, gestational diabetes mellitus and placental abruption. These complications may threaten the health of both mother and baby to varying degrees.
For example, pregnancy induced hypertension is one of the common risks faced by IVF women. In this case, the increased blood pressure of pregnant women may cause proteinuria, edema and other symptoms, and may even develop into pre eclampsia or eclampsia in serious cases, threatening the life safety of mothers and infants.
In addition, hormone drugs used in IVF may also increase the risk of gestational diabetes mellitus for mothers. Gestational diabetes will increase the chance of pregnant women suffering from pregnancy induced hypertension and fetal macrosomia, and may lead to placental insufficiency.
2. Problems caused by multiple pregnancy
IVF technology usually fertilizes and cultivates multiple fertilized eggs in the laboratory, and then implants multiple fertilized eggs into the mother, so the probability of multiple pregnancy is high. Multiple pregnancy may cause a series of health problems.
First, multiple pregnancies increase the risk of premature delivery. Premature infants often need additional care and medical support due to incomplete development of lungs and other organs at birth.
Secondly, multiple pregnancy may also cause twin fusion syndrome. This syndrome occurs in identical twins and occurs when the fertilized embryo does not divide completely. Twin fusion syndrome may lead to congenital malformations, organ sharing and other diseases, affecting the quality of life of infants.
In addition, multiple pregnancy also increases the risk of placental related complications, such as placental abruption, placental implantation abnormalities and placental regression.
3. Possibility of genetic defects
IVF technology cannot completely eliminate the risk of genetic diseases. Although IVF technology can screen out some specific genetic defects, such as chromosome abnormalities, there are still risks of other genetic diseases.
For example, if one or both parents carry genetic mutations, these mutations may be transmitted to the baby, leading to the occurrence of congenital diseases. In addition, IVF technology itself may also lead to the risk of some genetic diseases, such as cystic fibrosis.
In some special cases, in order to avoid the risk of genetic diseases, embryonic genetic screening or gene modification technology can be carried out. However, these methods also have ethical and moral problems, which require comprehensive discussion and prudent decision-making.
4. Psychological and social factors
IVF technology often requires patients to go through a long treatment process, which may bring some negative effects in emotional and psychological aspects. For example, long-term infertility treatment and IVF process may exert certain pressure on the couple's psychology and family relationship.
In addition, the society's views on IVF may also cause some pressure on patients. Discrimination or prejudice against IVF children may have adverse effects on their social and physical and mental health.
summary
Although IVF technology helps many infertile couples achieve their reproductive aspirations, it also has certain risks and sequelae. These risks include pregnancy complications, problems caused by multiple pregnancies, the possibility of genetic defects, and psychological and social factors. Before accepting IVF technology, patients should fully understand these risks and have detailed discussions and decisions with doctors.
