I’m sure that anyone working in a hospital can cough up a few dozen more.
RISUG has been invented in 1978,
is reversable, cheaper, zero side effects,
and with so far 0% failure rate when implemented properly,
Vasalgel, an improvement on RISUG by having a longer shelf-life,
has been invented around 2015.
So this stuff has been invented in the same year as the first Star Wars movie,
had gone through all trials multiple times with flying colors,
and instead we use knives and pills with large side effects.
If any invention could be been ubiquitous in use at a much earlier stage,
then this would be it.
It could and should have been widely used by the 1980’s.
For animal testing we have 3D printed human tissue.
So why test on animals if your question is “Does this stuff work on human tissue?”
The answer you’ll be getting is whether or not it works on mice.
Mice are not human.
