It is not uncommon for men to have children when they are old. Ahaher Chana112, a farmer in the former Soviet Union, got married and successfully got his wife pregnant and gave birth, setting a Guinness World Record. Seeing this, many people may be greatly encouraged, but individuals cannot represent the whole. Just because some elderly men have the ability to make women pregnant does not mean that most elderly men also have the same ability.
At the age of 80, the secretion of male hormones will also drop to the same level as that of female menopause estrogen secretion, and in this process, the age of male hormones will also suddenly drop, so men also have "menopause."
In other words, Ms. Tian, 67, and her husband, 68, can grow old together and have children, which makes many infertile young couples surrounded by lemons, which is really sour. Modern society is a society with such advanced technology. How do people realize their desire to "create evil people"?
As early as 1790, the British doctor John Hunter, as the father of experimental surgery, performed artificial insemination on her husband with severe hypospadias, which was a success and pioneer of artificial reproduction. From 65438 to 0978, the world's first IVF assisted reproductive medicine has entered a new stage since its birth. Nowadays, with the continuous development of science and technology, various "black technologies" to save fertility emerge one after another. In addition to the artificial insemination and IVF we are familiar with, we will study some new fertility techniques for them.
More severe than abdominal delivery, "uterine transplantation" gives birth to a new baby.
According to media reports, a woman in Sao Paulo, Brazil, successfully gave birth to a baby girl on 20 18 after receiving a uterus transplant from the deceased woman. The baby was born safely at 35 weeks. According to the The Lancet Journal of Medicine, 65,438+00 cases of uterine transplantation have been performed in the United States, the Czech Republic, China and Turkey, but none of the recipients succeeded in getting pregnant. This case in Brazil became the first successful case in the world of giving birth with a donor's uterus after death.
Do women who can't be mothers in the future because of uterine problems see the light of hope? Having said that, Bian Xiao can't help but sigh that the medical technology today is really amazing.
"In vitro version" of human uterus
Also last year, a research team of Philadelphia Children's Hospital in the United States made an "artificial uterus" for the first time through animal experiments, which enabled premature lambs to successfully pass the critical period, and its physiological function was similar to that of ordinary lambs. Their artificial uterus can create a growth environment similar to the mother's uterus for premature fetus, so that the fetus can continue to develop outside the mother's uterus.
If this technology can be applied to clinic, its prospect is immeasurable. Of course, some researchers have pointed out that this "biological bag" does not support the growth of the fetus 22 weeks ago. So far, it is still an insurmountable bottleneck to simulate the early growth environment of embryos in uterus. If this technology can be applied to humans, how many babies will be born in the future?
In the future, ai can also be pregnant and have children.
Can robots have children? You heard me right. As early as 20 17, the American company realdoll designed harmony, the world's first female sex robot. She is a combination of artificial intelligence and robot, which can not only simulate human body temperature, but also customize genitals and change face. In addition, the robot can also be equipped with a special "bioreactor system" to provide a suitable environment for the growth of human tissues.
