The fate of 200,000 babies frozen in test tubes, a current concern

Test tube babies are those embryos that remained frozen for years in liquid nitrogen because couples who sought medically assisted reproduction did not use them.
There is no exact figure for how many embryos there are in total, but it is said that there could be between 55 thousand and 200 thousand in Italy alone, where it has been raised as a concern.
By law, they cannot be eliminated, that is, undone, nor used for scientific research.
The Italian Ministry of Health has a project to recover at least some of them by allowing them to be "adopted" by couples seeking a child and having fertility problems.
So, a woman who cannot get pregnant can have a test tube baby implanted in her uterus.
This way, embryos are given life without leaving them frozen forever and without killing them.
The first steps regarding this issue have been taken.
A regulation is now needed to regulate this sensitive and complex issue.
