Well for humans that is not true yet - what you are talking about it NOT an injection at all
This is a combining of DNA to make a complete embryo
and so for humans the ONLY way to do this RIGHT now is use DNA (egg) from one partner, and then if the other partner has a brother - use the brother's DNA which will get close to having child for both of your DNA's
The injection you are hearing is 'Science Fiction' - it does NOT exist - this is a Dream that people are wishing for right now.
So Lesbian couple still require IVF to have a baby -
that is the joining of an Egg and Sperm from a donor - and many couples who have a brother from the other partner - use the brother's sperm.
I hope that helps
yes, that is correct - what you are reading or hearing about is pure science fiction - even test tube babies are only about 30 years old - so from what you are asking - the human being still has a long way to do
not true at all.
I can tell you that We are close to having the ability of using DNA from 3 people to make an Embryo - but that has not happened yet - still working on it.
