The harm of IVF to human body
IVF is a process in which sperm and eggs are fertilized in vitro and then fertilized eggs are implanted into the mother's uterus for pregnancy through assisted reproductive technology. Although IVF technology is of great significance in solving the problem of infertility, IVF is also accompanied by some physical hazards.

1. Increase of pregnancy complications
Compared with natural pregnancy, IVF pregnancy has an increased risk of pregnancy complications. First of all, IVF is carried out in an artificial control cycle, and drug intervention will make women's ovaries overstimulate, which is prone to ovarian hyperstimulation syndrome. Secondly, IVF technology is often accompanied by an increased risk of multiple pregnancy, which brings higher risks to both pregnant women and fetuses, such as premature delivery, low birth weight infants, congenital malformations and other problems.
In addition, there will be other complications during pregnancy, including pregnancy hypertension, anemia, pregnancy diabetes, etc. With the increase of these complications, IVF pregnant women need more care and medical intervention.
2. Increase of psychological pressure
IVF is a great emotional, psychological and physical test for couples. Infertility itself has caused psychological pressure on couples, and the choice of IVF technology has further increased this pressure. The success rate of IVF technology is not 100%, and every failure means a huge blow and disappointment.
In addition, the treatment process of IVF usually requires multiple attempts, which will keep couples in a state of tension and anxiety for a long time. They need to face the risks of injections, side effects of drugs and surgical procedures during recovery. These psychological pressures will have a certain negative impact on the psychological health of couples.
3. Risk of genetic defects
IVF technology cannot completely eliminate the risk of genetic defects. In the process of IVF, the genetic detection and screening of embryos are not 100% accurate. In addition, IVF may also have chromosome abnormalities during embryo implantation, leading to embryo implantation failure or abnormal development.
For some families with a family history of genetic diseases, IVF technology may not rule out the risk of genetic defects. Therefore, before IVF, couples should receive genetic counseling and genetic counseling to understand the possible genetic risks and related choices.
4. Social and ethical issues
IVF technology has also caused a series of social and moral problems. First of all, the high cost of IVF technology makes only some people can afford it, which further deepens the gap between the rich and the poor in society. Secondly, the emergence of IVF technology has also led to moral confusion and ethical challenges for couples who are troubled by infertility.
In addition, the IVF technology has also triggered people's thinking about the origin of life and ethical issues, such as whether embryos should be protected as babies have been born, and whether IVF technology conforms to human dignity.
Summary
The emergence of IVF technology provides hope for infertile couples, but it also brings some physical harm. The increase of pregnancy complications, the aggravation of psychological pressure, the risk of genetic defects, and social and moral problems are some of the effects of IVF that cannot be ignored. Couples should fully understand these risks before choosing IVF technology, and have a detailed discussion and consultation with professional doctors.
