Are test-tube mice different?

They are bolder and more confident, but have poorer memories, here is the story.

And humans?

Studies are needed to see if test-tube humans are similarly affected, he says...In the Western world, around 1% of children are conceived through assisted reproductive technologies. In one common method known as in vitro fertilization, eggs are fertilized in a test tube, cultured for a short while and then returned to the womb. Over a million 'test-tube' babies have been born worldwide. But little is known about the long-term effects of culturing embryos. The world's first test-tube baby, Louise Brown, was born just 26 years ago. There have been few systematic attempts so far to assess the long-term health and behaviour of these children.

Food for thought, perhaps we are engaging in social experimentation here without knowing it.
