When a couple fails to conceive with other assisted reproductive technologies, they can go for surrogacy. There are many couples, who failed to have a child due to medical or sexual issues, which are not curable through other means. They can hire surrogate mothers, who can give birth to their babies with help of assisted reproductive technology. Surrogate mothers can give birth to the child of concerned couple either formed through their own gamete or by using donated sperms and eggs through IVF.
To make the process of surrogacy legal and authentic, a legal agreement is made between the couple and the surrogate mother. This legal agreement with the surrogate mother declares consent of the surrogate for taking part in this process and gives birth to their baby and the authority of the baby, which lies with the couple, who are the genetic parents of the child.
In this type of surrogacy, the surrogate mother will nurture embryo created by IVF treatment in her womb and give birth to the child of the couple, who are genetic parents of the child. The baby is usually genetically different from surrogate mother. Gestational surrogacy is also known as gestational carriers.
This type of surrogacy involves eggs of the surrogate mother, who gives birth to a child naturally, hence is genetically related to the surrogate mother.
