Who Is the Biological Mother in Surrogacy? Egg, Womb and Law Explained

In gestational surrogacy, the biological mother is the woman whose egg created the embryo, not the surrogate who carries the pregnancy. This is usually the intending mother, or a donor when there is a medical reason. Under Indian law, the baby is legally the child of the intending couple.

In surrogacy who is the biological mother?

The word "mother" can mean three different things in surrogacy. Most confusion comes from mixing them up. Once you separate them, the answer becomes clear.

In a gestational arrangement, the surrogate is the birth mother. She is not the genetic mother and she is not the legal mother. You can learn more in our complete guide to gestational surrogacy.

In surrogacy whose egg is used in India?

In most cases, the egg comes from the intending mother. Her eggs are collected after hormone stimulation and combined with sperm in an IVF laboratory. The resulting embryo is then transferred to the surrogate's womb.

The sperm usually comes from the intending father. This means the baby is genetically related to both parents. The surrogate only provides the womb and the care of pregnancy.

Sometimes the intending mother cannot use her own eggs. This may be due to very low ovarian reserve, early menopause, or surgery. In those cases, a donor egg may be considered.

Can the surrogate use her own egg?

No. Indian law requires the surrogate not to provide her own egg. The embryo must be created separately and then transferred to her womb.

When the surrogate's own egg is used, the arrangement is called traditional surrogacy. She would then be the genetic mother. You can read how it differs in our page on traditional surrogacy.

The rules on this are set by the Surrogacy (Regulation) Act, 2021. You can check the official text on India Code.

Does the surrogate share DNA with the baby?

In gestational surrogacy, the surrogate does not pass on her DNA. The baby's DNA comes from the egg and the sperm used to create the embryo. A genetic test would show the baby matches the egg provider and the sperm provider.

The surrogate's body supports the baby's growth through nutrition and the placenta. That care is real and deserves respect. But it does not make her the genetic mother.

Many parents worry that the baby will look like the surrogate. Our page on common myths about surrogacy addresses such concerns.

When can a donor egg be used in surrogacy?

A donor egg may be used only in limited situations. The intending mother must have a medical condition that makes her own eggs unusable. This must be certified by the District Medical Board.

The rules on donor gametes in surrogacy were amended in 2024. Please check the current position on the National ART & Surrogacy Portal before you plan.

The rules expect the embryo to be created with at least one gamete from the intending couple. Your clinic must also be registered under the ART (Regulation) Act, 2021.

Who is the biological mother with a donor egg?

With a donor egg, the donor is the genetic mother. The surrogate is still the birth mother. The intending mother is the legal mother and raises the child.

Egg donors in India are bound by the ART rules. They do not have parental rights or responsibilities toward the child. Their identity is kept confidential. This is a strict legal requirement, not just a clinic policy.

Who is the legal mother of a child born through surrogacy?

The intending mother is the legal mother. The Surrogacy (Regulation) Act, 2021 says a child born through surrogacy is deemed the biological child of the intending couple. This applies in the way the Act describes, and the surrogate has no parental claim.

Before the procedure begins, the intending couple must get the required certificates. They also need a magistrate court order on parentage and custody. These steps protect the child, the surrogate and the parents. The surrogacy procedure guide shows where each step fits.

Only altruistic surrogacy is allowed in India. Commercial surrogacy is banned. Our guides on whether surrogacy is legal in India and altruistic surrogacy explain this in practice. For a neutral summary of the Act, read the PRS Legislative Research note.

What should you ask your clinic about the egg source?

Before any treatment begins, ask clear questions. A good clinic will answer them in writing.

• Will my own eggs or donor eggs be used, and why?
• Is the clinic registered under the ART (Regulation) Act, 2021?
• Which certificates and approvals do we need for our case?
• How will the donor be screened, and how is her consent recorded?
• How will the embryo be labelled and tracked to prevent mix-ups?

Registration and approvals are done online. Our page on national ART and surrogacy portal registration explains the steps.

How do you talk to a child about their origins?

Honest, early and simple conversation tends to work better than a late surprise. Many families begin with age-appropriate words when the child is small. They repeat the story as the child grows.

If a donor egg was used, you can explain that a kind woman helped by giving a cell. You can then explain that you are the child's parents. If your own egg was used, you can say that another woman helped the baby grow until birth.

Your doctor or a counsellor can help you plan the words. Every family decides this in its own way. There is no single right script. What suits one family may not suit another. For more background, see what surrogacy is and who the surrogate, parents and egg donors are.

Frequently Asked Questions

In surrogacy who is the biological mother?

The biological mother is the woman whose egg is used to create the embryo. In gestational surrogacy, this is the intending mother or an egg donor. The surrogate carries the baby but is not genetically related to the child.

In surrogacy whose egg is used?

Usually the intending mother's egg is used. If a medical reason stops her from using her own eggs, a donor egg may be allowed. The surrogate's own egg cannot be used under Indian law.

Whose eggs are used in surrogacy if the mother cannot produce any?

A donor's eggs may be used, but only within the limits of Indian law. This requires certification from a District Medical Board. The rules were updated in 2024, so check the National ART & Surrogacy Portal for the current position. Your clinic should confirm eligibility before starting.

Is the surrogate the real mother of the baby?

No. The surrogate is the birth mother, but not the genetic or legal mother. Under the Surrogacy (Regulation) Act, 2021, the child is deemed the biological child of the intending couple.

Will the baby look like the surrogate?

The baby inherits genes from the egg and sperm providers, not from the surrogate. Looks depend mainly on those genes. This is why the baby may resemble the egg provider and the father.

Does a donor have any rights over a child born with a donor egg?

No. Under the ART rules, a donor has no parental rights or duties toward the child. Donor details are kept confidential. The process must go through a registered clinic or bank.

Can a surrogate mother be paid for providing her egg or womb?

No. Commercial surrogacy is banned in India, and only altruistic surrogacy is allowed. The surrogate cannot provide her own egg. The Act allows certain medical expenses and 36 months of insurance cover for the surrogate. Anything beyond that can be an offence, so stay within the law.

How can you start your surrogacy journey?

Egg source, eligibility and paperwork differ from one family to another. If you would like calm, clear guidance based on your situation, you can speak with the VinsFertility team. Outcomes vary from person to person. We will explain your options honestly, with no pressure.
