“Experiment” is a tool of the modern science. The usage of this word in this context is not appropriate.

There is no evidence. There either is a source which mentions this or there isn’t one. I have not seen, nor found such a source. The story is most likely made up by some modern idiot.

This story is also beyond ridiculous. I wonder how many human fetuses an average ancient greek has seen, but surely, it can’t be that many.
