Surrogacy is very important to infertile couples. Most people have a desire to have children that are genetically their own. For whatever reason there are still people that do not believe adopted children would be their own. For these couples, surrogacy is sometimes the only chance they have at becoming parents.
Personally, I feel there is another way to become a parent than to choose the sticky situation of surrogacy. Adoption is a lovely way to give a child a chance at life that they wouldn't have had otherwise. And while people often complain about the cost, adoption can be far less expensive than surrogacy, especially if the child is not a newborn. Most adoptions cost under $5,000, and they can even be free. Surrogacy is stressful for all involved, extremely costly, and it sadly doesn't guarantee the end result of a child.
