IVF is a type of assisted reproductive technology used for infertility treatment and gestational surrogacy. The embryo implanted in gestational surrogacy faces the same risks as anyone using IVF would. A Medicare rebate is not available for IVF treatment for surrogacy. Embryo transfers for purposes of gestational surrogacy are also covered. Both were born via gestational surrogacy. Some gestational surrogates report emotional distress during the process of surrogacy. The incident raised questions about the ethics of gestational surrogacy. The law makes surrogacy agreements unenforceable. Only married couples as Thai residents are allowed to make commercial surrogacy contracts. Gestational surrogacy (also known as host or full surrogacy) was first achieved in April 1986. The citizenship and legal status of the children resulting from surrogacy arrangements can be problematic. Numerous ethical questions have been raised with regards to surrogacy. This sparked some criticism due to the ethical issues with surrogacy. Such arrangements were prohibited by the Surrogacy Arrangements Act 1985. Many countries do not have laws which specifically deal with surrogacy.
