Advantages and disadvantages of IVF assisted pregnancy technology

In recent years, I have always heard the term test-tube baby. Celebrity figures such as Zhang Ting and Chen Mingzhen all took test-tube tests many times before successfully conceiving a child. They suffered a lot and suffered a lot. Of course

This is also related to their age and physical factors, and cannot be completely counted on the technology of IVF assisted pregnancy. In fact, IVF assisted pregnancy technology has helped infertile families achieve fertility

Dream, although the process is very bitter, the result is still very sweet.

IVF refers to in vitro fertilization-embryo transfer technology, which uses artificial means to promote fertilization of eggs and sperm in vitro and undergo early embryonic development, and then transfer the embryo to the mother's uterus.

The baby born.

Induction of ovulation, monitoring of follicles, sperm collection, in vitro fertilization, cultivation of fertilized eggs into embryos, transplantation, one week after transplantation, use test paper or pregnancy test stick to check whether pregnancy is pregnant, and conduct B-ultrasound after 20 days of pregnancy

To determine the implantation site and number of embryos.

The first-generation IVF technology is a kind of assisted reproduction that places a female's eggs and male sperm in a petri dish and mixes them, allowing the egg to be naturally fertilized and cultivated into an embryo, and then transplanted into a female's uterus.

Technology. It is mainly used to solve female infertility problems, such as fallopian tube obstruction, endometriosis, etc.

The second-generation IVF technology, also known as intracytoplasmic single sperm injection of oocyte, is to directly inject sperm into the cytoplasm of oocyte to achieve the purpose of assisting pregnancy. It mainly deals with male infertility. For example,

Such as oligospermia, asthenospermia, abnormal sperm, and congenital or acquired defects, obstruction, or obstructive azoospermia caused by surgical resection.

The third-generation IVF technology is pre-implantation genetic screening. Before embryo implantation, PGS is used to detect chromosome number and structural abnormalities in early embryos, mainly through 2

3 Test the number of chromosome structures and compare them for any abnormalities in genetic material.

Due to the increasing prevalence of late marriage and late childbearing, the number of infertile people around the world has increased significantly. In the more developed regions, the more significant this phenomenon becomes, and this has become a serious social problem. Test tube

The birth of baby technology has brought good news to the vast number of infertile families. However, many people are still skeptical about IVF.

The conception process in a normal woman is that sperm and eggs meet in the fallopian tube. The sperm and egg combine to form a fertilized egg. The fertilized egg moves from the fallopian tube to the uterus, continues to develop into an embryo and implants, thereby achieving pregnancy.

IVF is in which sperm and eggs are fertilized in vitro and then artificially transplanted into the female uterus.

Scientists have tracked and recorded a group of children born through test-tube technology and compared them with children born naturally. After 5 years of observation and control, it was found that they had higher intelligence levels

There is no difference between language, behavioral ability and other aspects from ordinary children.

The world's first test-tube babies are now in their thirties and thirties. They live a normal life and are engaged in work no different from ordinary people. Those who have started a family have naturally become pregnant and have children. Their children are similar to other common people.

There is no difference between children.

For women, an important obstacle to pregnancy is age. After women are 35 years old, the quality of eggs drops significantly, and the chance of developing chromosomal abnormalities increases significantly. Women over 40 years old

The egg reserve is almost exhausted, the chance of egg chromosome abnormalities is higher, and the abortion rate and fetal teratogenicity rate are higher than that of young pregnant women.

Other risk factors include poor living habits, drugs, toxic substances, radiation, chemical reagents, viral infections, etc. The older you are and the longer you are affected, the lower your fertility. Positive cause

In this way, many women now choose to freeze their eggs to preserve fertility and avoid aging of their eggs due to aging and the long-term effects of external adverse factors. When they have the intention to have children, they will use IVF technology.

Achieve the purpose of pregnancy and protect the child's health.

Of course, a series of studies in recent years have shown that older men have a high chance of abnormal genetic material. Therefore, reproductive experts have always recommended that childbearing should be done early and try to avoid contact.

harmful factors.

Elderly people who are infertile choose IVF, especially the third generation IVF. Through testing and screening, embryos with genetic diseases and chromosomal abnormalities are excluded, and healthy embryos are selected for transplantation. Not only

It can solve the problem of infertility and achieve eugenics and postnatal care.
