Can there be children without a uterus?Of course it is impossible! But if you transplant a uterus, maybe you can.Recently, the Pearl River Hospital of Southern Medical University announced that it has made major breakthroughs in the research of uterine transplantation, which is expected to help the uterine lack of feminine "mother dreams".
As soon as the news came out, while everyone was amazed by the progress of medical technology, some people even joked that "men can get pregnant in the future."Men's baby, is this reliable?
Experts reveal the mystery for you.
Uterine transplantation, my country needs to overcome three major problems
In early September 2014, a 36 -year -old woman in Sweden gave birth to a healthy baby boy through uterine transplantation, becoming the world's first successful case of uterine transplantation.At present, there are only 11 cases of uterine transplantation in the world, and China has not been for the time being.
Experts pointed out that the first domestic hospital to successfully conduct uterine transplantation experiments to the Ganges monkey of the longevity.The breakthrough progress of this study lies in that after more than 5 years of hard work, the current 6 animal uterine transplantation has been successful.
According to the rules of international uterine transplantation "The Montreal Convention", the success of animal experiments has laid a good foundation for the successful realization of human uterine transplantation.
Although it has made major breakthroughs in technology, experts revealed that the specific timetable of uterine transplantation surgery has not yet been determined.Compared with other organ transplants, there are still many difficulties in uterine transplantation that need to be overcome.
First of all, the requirements for uterine supply are more stricter, and the uterine matching of the body and the receptor and the immune exclusion situation must be considered.It is currently recommended to transplant between direct blood relatives.
Secondly, uterine transplantation has high technical level requirements for doctors and hospitals. In addition to the experience of successful experiments in the hospital, the choice of uterine vascular choices and whether it is in line with.
Finally, we must also solve the choice of anti -immune rejection drugs. We must not only ensure the survival of the transplanting uterus and to ensure future conception. The Zhujiang Hospital is currently conducting relevant clinical research to solve the effect of drugs on the fetus during pregnancy.
In addition, uterine transplantation is not allowed to do.
Before transplantation, a physical examination should be performed on the supply receptor to eliminate diseases such as genetic diseases and tumors. It is also necessary to ensure that the receptor has normal eggs. After the matching type is successful, the receptor must take eggs and fertilize through the auxiliary reproductive technology, and freeze the embryo to freeze the embryo.spare.
If the supply is already, the uterine function is needed to "restart" with drugs.At this time, transplantation can be performed.After surgery, in the normal circumstances of determining the uterine function of transplants, the embryos are implanted in advance, and the fetus is mature to perform caesarean surgery.
Expert: Whether it can succeed is to discuss
Some experts have different views on solving infertility through "uterine transplantation".
Experts believe that even if technological progress makes uterine transplantation possible, when general patients have uterine infertility or other diseases, their problems are often not isolated, and they are mostly related to the patient's ovarian function and chromosomal abnormality.It may still face infertility.
In addition, the source of uterine transplantation is also very difficult.It is almost impossible to transplant a healthy woman's uterus. It is necessary to meet the conditions such as major accidents in the donors and the uterus is not damaged, and it can be successfully matched with the patient.
The reporter learned that at present, the main source of uterine transplantation is the living donation of direct relatives, live menstrual donations, or patients with menopausal women or patients with brain death. Some have tried to transplant from the dead, but the effect is not ideal.
"Men can get pregnant" is misunderstanding
A few days ago, experts said at the forum: "The uterine transplantation is expected to be supported by the Ethical Committee, because the transplantation uterus is only a place for transplanting a fetal fetus, and it does not touch the change of husband and wife sperm and eggs."
Regarding the "future men can also get pregnant in the future", experts responded that from technical speaking, medical transplantation is not impossible in the future, but it is not very ethical.
From the perspective of experts, men's pregnancy is not realistic in medical technology.The nursing life of the uterus requires the estrogen in women to maintain it. If the uterus is transplanted to men, a large amount of estrogen drugs need to maintain the normal function of the uterus.This is undoubtedly a huge harm for the male health of male hormones.
In addition, the moral concepts involved in men's pregnancy are even more controversial, and it is difficult to get recognition from the medical community.
