SuRROgacy

I have been curious to know more about Surrogacy. It might not a
familiar topic, and first time I knew it because I have watched a
Korean serial with Surrogacy as the main point.
Stated in Wikipedia Surrogacy is a method of reproduction whereby a
woman agrees to become pregnant and deliver a child for a contracted
party. She may be the child's genetic mother (the more traditional
form of surrogacy), or she may, as a gestational carrier, carry the
pregnancy to delivery after having been implanted with an embryo, the
latter being an illegal medical procedure in some jurisdictions.
In my personal opinion, this method can be helpful to a couple whom
cannot have baby in normal way, even perhaps in some cases that the
woman who carries the baby is being paid.
But in other hand, there is another affect to this kind of method,
where when a woman have a baby in her womb there will be a connection
between her and the baby, and when the baby is born perhaps it could
be super hard to let the baby go, even she knows the baby is not hers.
Well, finally everyone has their own opinion and something will
always has positive and negative impact
Do you have any opinion?
