In the application of IVF technology, the use of ovulation promotion technology can promote the simultaneous development of multiple follicles. When the number of follicles developing at the same time is too large (such as more than 30), ovarian hyperstimulation syndrome can easily occur
The syndrome is manifested by symptoms and signs such as abdominal distension, ascites, and oliguria, which is mostly caused by the high sensitivity of some women to ovulation inducing drugs. This syndrome is a self-limiting disease and most women do not require special treatment
Only a very small number require inpatient intervention, and the prognosis is good. In recent years, with the continuous optimization of clinical protocols and the decrease in the dose of ovulation inducing drugs, this phenomenon has shown a downward trend year by year. Another of IVF technology
A potential side effect is multiple pregnancy. In addition to increasing the physical burden on women during pregnancy, it will also increase the risk of premature birth, miscarriage and various obstetric complications, causing physical and mental trauma to women. However, with single
Embryo transfer technology is becoming more mature, and the number of multiple pregnancies is gradually decreasing.
Birth defects are a focus of great concern to expectant parents. In 2005, a U.S. scientific research team conducted a study on 1500 IVF infants, 340 artificially inseminated infants, and 8400
Compared the incidence of birth defects in naturally conceived infants, the results showed that the defect rates of the three were 6.2%, 5.0% and 4.4% respectively. The slightly higher rate of birth defects in test-tube babies is mainly due to acceptance of
Women assisted in IVF generally have unfavorable factors such as older age and more primary diseases. These factors have an impact on the development of the embryo and fetus, which in turn increases the risk of genetic defects in the baby. Divide by
In addition to the above-mentioned research, there are differences in current reports on the rate of birth defects in vitro babies, and whether this will lead to an increase in birth defects is still controversial. On the second generation of IVF technology (intracytoplasmic
Single sperm injection technology), although some people are concerned that the operation of injecting sperm into the egg may damage the egg and cause abnormal development in children, most studies have not confirmed that this technology will increase the rate of birth defects.
Under certain circumstances, IVF technology can even help reduce the occurrence of genetic diseases. For example, the third-generation IVF technology-pre-implantation genetic disease diagnosis can effectively avoid a variety of
The intergenerational transmission of human genetic diseases, such as thalassemia, congenital Down's syndrome, etc., is an advantage that natural conception cannot achieve.
The intelligence level and emotional intelligence development of IVF babies are important issues that expectant parents pay close attention to. Early research has found that the rate and structure of sexual staining aneuploidy in children born with IVF technology
The abnormal rate increased slightly, and the intellectual development level was slightly inferior to that of naturally conceived babies. However, scientific research results from the University of Oxford in the United Kingdom in recent years have shown that 3-year-old test-tube baby has a better cognitive ability
.
transcends naturally conceived babies. A number of recent studies have further shown that test-tube babies of different age groups such as 5, 8, and 10 years old have significant differences in emotional intelligence, intelligence, and exercise ability.
Compared with children born, there is not only no gap, but there is even a slight advantage in some aspects. American researchers conducted a study on 423 IVF students aged 8 to 17 and 372 naturally conceived students
Observation and comparison showed that the mental function of the 8-year-old test-tube baby group was better than that of naturally conceived children, and the balance of the 10-year-old test-tube baby group was better. In-depth investigation found that the excellent performance of IVF
Most of the parents of the children have college degrees or above, and the mother is relatively old. It can be seen that the education level of parents and the age of mothers have a higher impact on the cognitive ability of descendants than the fertilization method
As such.
Couples with genetically predisposed diseases such as oligoasthenospermia and polycystic ovary syndrome often worry that the disease will be passed on to the next generation and affect its fertility. In fact, there is no need to worry too much about the next generation
fertility problems. Currently, IVF technology can help most couples realize their childbearing dreams, and with the continuous advancement and deepening of scientific research, it is expected to provide fertility assistance to more people. Although
Modern medicine cannot ensure that every test-tube baby is absolutely healthy (natural reproduction cannot ensure that newborns are completely healthy), but it is clear that the vast majority of test-tube babies are in normal and healthy conditions
In the healthy state, IVF technology does not significantly increase the risk compared to natural fertility. For couples who have difficulty conceiving naturally, IVF technology is undoubtedly a valuable reproductive option. Given its
With significant advantages and relatively low risks, it is recommended that relevant couples actively try and work hard to build a happy family.
