Images and Examples
I like the content so far, explaining the difference between the two types of surrogacy, and the effects of it. Maybe include a section of examples of other countries with the highest rates of surrogacy, or some policies or reasons why people would do it in that country, to compare if they would be the same in certain ones. Why is it that more often, we see those in less fortunate countries doing surrogacy? Are there any problems arising, for those who are involved in a surrogacy, then later on decide to want the baby? Complications? Advantages? Disadvantages?
Also, remember that charts can be helpful in showing these rates of surrogacy, and images as well so your page is more colourful and helps the reader!
