In the United States, a baby was born who developed from an embryo frozen 20 years ago
The mother was a 42-year-old woman who had been treated for infertility for a long time. Doctors advised her to artificial insemination, and offered to participate in the experiment. The woman was injected with an embryo that was frozen in 1990. In the cryochamber, he remained viable, after which he developed normally for all nine months. In May, she gave birth to a healthy boy weighing over three kilograms.
It should be noted that this is the longest shelf life of the fetus in the cryobank, which ended in the birth of a healthy baby. Until now, the "oldest" embryo was frozen 13 years ago. The parents from whom they received the embryos successfully acquired a child, and the remaining embryos were anonymously offered to other wishing spouses. Children from these embryos are biological brothers and sisters, albeit 20 years apart.
This event caused controversy among scientists. They worry if this practice will disrupt the natural succession of generations. In fact, a newborn baby could be already 20 years old, and in theory it is possible that test-tube babies will be even older than their parents.
