Firstly, intended parents are strongly recommended to learn as much as they can about the process, the parties involved, the legal issues surrounding it—which
can vary from state to
state or by country—, the medical process... Even if this seems to be a disadvantage at the beginning, it will contribute to reducing the number of potential risks and, in short, to help you succeed.
Secondly, prospective parents should be aware that being matched with a compatible surrogate can take time. Again, this should not be taken as a con, but as a major advantage: The higher the number of things you have in common, the better things will be working throughout.
Thirdly, stay aware of your finances to make the process more comfortable. Make sure that you are aware of the fees and costs involved before getting started.
