Chen Huanran, a plastic surgeon at the Union Medical College Hospital affiliated to China Medical College, said: "The development of medicine is advancing by leaps and bounds. Judging from the current medical level, it is entirely possible for men to have children. " Chen Huanran has another identity-a plastic surgeon in the first gender reshaping center in Asia, helping some patients with gender confusion to re-establish their gender. Modern medical means are enough to make transsexual surgery fake, but for many transsexuals who have changed from men to women, there is still a big problem-although they have women's names, they cannot have women's fertility. Many transsexuals treated in Chen Huanran in the past (male to female, hereinafter referred to as the same) divorced their husbands because they could not have children after marriage. This made Chen Huanran start thinking about how to make these transsexuals truly become a complete woman. Professor Winston, a famous British medical expert, also mentioned his view on the possibility of male having children in his book "In vitro fertilization revolution"-"Male pregnancy is actually just like female ectopic pregnancy, which is absolutely possible. Doctors can use advanced technology to transplant embryos into male abdomen; When the embryo is mature, the baby will be born by caesarean section. Because the placenta itself has the hormones needed to give birth to the fetus, it does not have to develop in women. " Chen Huanran summarized the specific operation process into five steps through preliminary research: First, take an egg and sperm and inseminate them in vitro. Second, when the fertilized egg divides to a certain extent, the embryo is placed in a specific part of the man's abdominal cavity and pregnancy begins. Third, supplement estrogen and progesterone to the "quasi-male mother" through the catheter. Fourth, after six or seven months of pregnancy, the "male mother" will be delivered by caesarean section. Fifth, finally put the fetus in an incubator. The key problem to be solved Judging from the technology that human beings have mastered, most technologies from one end to the other have been solved. Specifically, at present, IVF is a mature technology, and the third generation of IVF has been produced in China. Therefore, the first step for a man to have a baby-taking sperm and eggs, then cultivating them into embryos and implanting them in his mother's body, is very likely to be completed smoothly. And the last step is not a problem. Because a man's abdominal muscle pressure will hinder the baby's growth, so the pregnant fetus must not be full-term, and the current technology can save the fetus as long as it takes more than 28 weeks. Therefore, it is not a big problem to have a caesarean section after the man is pregnant for 6-7 months, as long as he can stop bleeding successfully. The key problem now lies in the intermediate link. The first is how to find a place where embryos can grow and develop in a man's abdominal cavity and simulate an environment suitable for pregnant women. It must have four requirements: rich blood and nutrients; There should be a certain space to facilitate the growth of the fetus; There should be no important blood vessels, nerves and organs around to avoid being oppressed by the fetus; It is also easy to take out by caesarean section. Secondly, there are many unknown variables to solve the monitoring problem of hormone supplementation for "prospective male and female", which is difficult to grasp. Another thing that must be taken into account is that estrogen supplementation may cause male breasts or breasts to enlarge and appear feminine, which is a problem that needs to be solved after the fetus is born. According to Dr. Chen Huanran, foreign experts have done a lot of relevant research on these two points and provided abundant information. We are fully capable of solving these problems. Within ten years, it will definitely become a reality for men to have children. Dr. Chen Huanran emphasized that at the beginning of 2002, Dr. Liu Hongqing, a Chinese scientist from Cornell University Reproductive Medicine and Infertility Research Center, used tissue engineering technology to reconstruct human endometrium in vitro for the first time in the world. This in vitro reconstructed endometrium is not only identical to human endometrium in tissue structure, but also similar in function. Artificial endometrium not only provides intellectual support for the topic of "male pregnancy", but scientists also have a bolder idea-in the future, artificial uterus can be developed without human body and an "artificial uterus factory" similar to sperm bank can be established. One day in the future, a couple who want to have children only need to ask a doctor to extract sperm and eggs from their own bodies and put them in a "workshop" of the "artificial uterus factory". June 5438+10 The pain of pregnancy will turn into a quiet wait, and they can get their own flesh and blood back. In Chen Huanran's view, it is better for men to have children than for machines to have children. Don't be surprised if one of your male colleagues tells you that he has taken maternity leave one day in the future. No one can stop the pace of science.
