Surrogacy is illegal in some places and countries.

Adoption on the other hand can be a risky path, leading to a different kind of problems, and some are very hard for parents. Everybody wants their sons being healthy and able to have a normal life but this is not always guaranteed with adoption. Some countries use shady practices and lie to the parents to obtain an emotional (not logical) choice. The cheaper the worst. Systematic racketeering is the minor of them. "Forgetting" about some important condition or omiting relevant medical information is much worse.
