Other human rights advocates are concerned about the conditions under which surrogate mothers are held by surrogacy clinics, which exert a great deal of power and control over the lender pregnancy process.   Isolated from friends and family and under the pretext of providing adequate prenatal care, it is argued that surrogate mothers could face psychological challenges that cannot be offset by the (limited) economic benefits of surrogacy.   There are other psychological problems, such as the effects that surrogate mothers emotionally detach themselves from their babies while waiting for the path of birth.  Surrogacy is an agreement often supported by a legal agreement whereby a woman (the surrogate mother) agrees to give birth to another person or person who becomes a parent after the birth of the child. The embryo implanted in the gestational loan maternity unit is exposed to the same risks as anyone using IVF. Preimplantation risks of the embryo include involuntary epigenetic effects, the influence of the media on which the embryo is grown, and the undesirable consequences of invasive embryo manipulation. Often, multiple embryos are transferred to increase the likelihood of implantation and, when multiple pregnancies occur, the risk of replacement and the risk of embryos are more likely to be affected.  Gestational carriers offer a hard-working parent who has suffered enormously to start their own family. In this context, how do we protect everyone in this type of arrangement? First, the parties must enter into a gestation contract. Indiana declares surrogacy agreement null and void and contrary to public policy. However, where a decision is to be made on parentage, the courts should not base their analysis of the best interest on the mere fact that a person has entered into a surrogacy agreement. The historical legal assumption was that the woman giving birth is the legal mother of that child, and the only way for another woman to be recognized as a mother is through adoption (usually requires the formal task of parental rights by the birth mother). The most frequently reported motivation, given by gestational surrogats, is an altruistic desire to help a childless couple.
 Other less frequently cited reasons are enjoyment of the experience of pregnancy and financial compensation.  Uruguay is a small country of 3,467,054 inhabitants, as indicated in the 2015 census . The infertility rate of this population is estimated to be between 15 and 18% . Among the most liberal countries in the region, the Uruguayan Parliament passed an arts law in 2013 (Ley 19.167/2013) that included ART coverage in the Uruguayan public health sector (Article 3). Article 25 refers in particular to surrogacy, which stipulates that surrogacy contracts are unhinged, unless the mother is considering has a disease that hinders her ability to carry the pregnancy until childbirth.
