The "IVF" was accompanied by the development of inrtinet insemination technology. It was initially successfully studied by British obstetrician Patrick & Bull; Stapo and physiologist Robert & Bull.
The birth of the "IVF" caused a sensation in the world's scientific community, and it was even a major pioneering agency called human reproductive technology. It also opened a new way for therapeutic disease.
"IVF" is a combination of sperm and eggs in the test tube to become fertilized eggs, and then send it back to the woman's uterus (embryo egg transplantation), then let it be in the uterine cavityLike normal pregnant women, she is pregnant to a full moon, and babies are given normally.For wives with diseases such as fallopian tubes, they can take mature egg cells directly from the ovaries through surgery.
Then mix the sperm of her husband in the test tube to let them combine in vitro into fertilized eggs.For husbands with less sperm or weak sperm activity, they can choose strong sperm from his semen through an extremely small courage straw, and directly inject it into egg cells to form fertilized eggs.
After the fertilized eggs form an early embryo in vitro, they can move into the wife's uterus.If the wife's uterus has a disease, the early embryo can also be moved into the female uterus of the women who voluntarily become a surrogate mother. In this way, the baby born has two mothers.The mother of his flesh and blood.The generation of this technology brings the gospel to couples who can produce normal sperm and eggs but cannot have birth for some reasons. Now this technology has been carried out in some places in my country.
In 1944, Americans Locke and Menjin made this attempt for the first time.The first IVF & BULL in the world; Louis was born at 23:47 on July 25, 1978 at the Oldm Hospital in the UK. Since then, the research has developed extremely rapidly.A country.The total number of IVFs around the world has reached thousands of.Several medical schools in my country have started this study, and Beijing Medical College has been successful in 1985.
But which baby should I test tube babies born with a pregnant maternal mother live with?What should I do if both mothers are unable to distinguish him?Such a problem is difficult to solve by science and technology alone.From here you can see that while biological science and technology benefit humanity, it will also bring some moral and ethical problems to humans, which should attract everyone's attention.
