The genetic identity of a baby born to a surrogate pregnancy depends on who contributes the genetic load [eggs and sperm]. For example, for homosexual couples it is generated in 50% of the donor of the ovum, and the other 50% is from one of the parents.
In the case of a heterosexual couple, if the parents of intention provide semen and eggs, they will share 100% of the genetic load with the baby.
The surrogate pregnant woman cannot provide the ovum, so she will not share a bond with the baby, limiting herself to gestating in her womb.
To get into the matter, we can define surrogate motherhood as an assisted reproduction technique that takes place when a single person, a marriage or a couple, want to have a child, but arrange pregnancy with another woman, so that, once given after birth, the pregnant mother renounces the maternal filiation to give it to the contracting person or partner.
It is a complex and expensive procedure, both personally and economically, in which many people and professionals intervene, but which can be simplified by choosing the correct professionals who will direct the process, and who provide a good advice and assistance.
The cost will vary according to the country in which the pregnancy is carried out, being obviously more expensive in the countries where greater guarantees and legal security are offered, such as the United States.
However, a closed price cannot be estimated, since it will vary depending on the different vicissitudes that may arise.
Normally, an embryo that has previously been fertilized occurs, normally through in vitro fertilization, performed in the laboratory through the union of the ovum and sperm, which will be implanted in another woman who gives or rents her uterus, to continue the pregnancy. The embryo will be formed either by genetic material from the parents or by donated material.
IIt may be the marriage itself, a heterosexual couple or a single person, who cannot carry out a normal pregnancy, due to genetic causes, disease, age or simply because they do not want to do so, who contribute their own egg and sperm without donation, known as «parents intentional "or" future parents ", and who will be the biological parents of the baby, although it may also be done through total or partial donation of genetic material.
The total cost varies approximately between $ 95.000 and $ 280.000 (or between € 80.000 and € 240.000), depending on factors such as: Need to resort to donating eggs and / or sperm. State in which uterine surrogacy is performed. Number of IVF attempts necessary to achieve the pregnancy of the pregnant woman.
