My wife is considering acting as a surrogate mother for a friend who is
having difficult with in vitro fertilization. Her embryos won't implant.
Both of us couples are Christians. My wife and I have 3 kids and
although she doesn't want another child for us she is willing to carry
one for her friend. What are your thoughts about entering into this
First, I consider surrogate parenting a very risky venture. Just because your wife is able to intellectually say she will give up the baby to your friends when the time comes, does not mean she will be able to do so emotionally. Carrying a baby for nine months creates a powerful bond that is not easily broken. This is easily seen in teenage mothers who often change their minds about giving their baby up for adoption after birth. The surrogate mom can rationally say and believe "this baby is not mine," but her emotions find it difficult to believe this after carrying the child for nine months.
Since there is also a relationship among friends here the risk is even greater, because even just a hint of wavering as the time of birth approaches could be interpreted as betrayal. The mother acting as the surrogate would also be faced with seeing this child regularly and having the pain of separation renewed frequently.
Second, there is the sacrifice of the family of the surrogate mother. Her husband and children will need to endure the difficulties of a pregnant mom and wife for a child that is not theirs. How is this explained to her children particularly? Pregnancy always involves risk and this is asking a lot of the family. All parties would need to seek God's peace before proceeding. If anyone is hesitant, I would not proceed.
Third, I am troubled by the implications of surrogacy to the concept of a couple becoming one flesh through marriage and child-bearing. I would want to be sure of the Lord's leading in this regard because I just have a suspicion that surrogacy may violate this principle by having someone outside the marriage carry a baby from another union.
While I do not see a clear and unambiguous reason to say no, that is my advice due to the number of potential problems and pitfalls. We sometmes have to face difficult decisions with couples dealing with infertility because we seem to say we are unsympathetic to their dilemma. But we must also be realistic to realize that God does not promise that all potential solutions to all our problems are Biblical. Having a child of our own is not promised or demanded. Often a family's unwillingness to adopt is not just rooted in the natural desire to have children but in a selfishness that only wants "our" child.
If it were me, I would not do it.
