The core biological difference lies in whose egg is used to conceive the child. In traditional surrogacy, the surrogate mother's own egg is fertilised with sperm, making her the biological, genetic mother of the baby. In gestational surrogacy, the surrogate carries an embryo created through IVF using the intended mother’s (or a donor’s) egg and intended father’s (or donor’s) sperm. Therefore, a gestational surrogate has no genetic relationship to the child.
In India, clinical practice and legal frameworks strictly recognise gestational surrogacy to ensure genetic and medical clarity. We recommend consulting a fertility specialist to understand what applies best to your clinical scenario.

From a biological standpoint, the distinction is entirely about genetic lineage. In traditional surrogacy, the surrogate contributes her own oocyte (egg), which is fertilised via artificial insemination or IVF. Consequently, she shares 50% of her DNA with the newborn.
Gestational surrogacy, however, involves transferring an embryo created entirely outside the surrogate’s body using the intended parents' or selected donor gametes. Biologically, the surrogate provides only the uterine environment for nourishment and gestation, sharing zero genetic material with the baby. In Indian clinical practice, gestational surrogacy is the accepted standard. Please consult a qualified fertility specialist to discuss reproductive pathways suited to your medical history.

Understanding the biological difference helps intended parents make informed emotional and clinical choices. Traditional surrogacy uses the surrogate's natural egg, meaning the surrogate is genetically related to the baby.
Gestational surrogacy, by contrast, relies purely on In Vitro Fertilisation (IVF). The embryo is formed using eggs from the intended mother or an approved donor, meaning the gestational carrier has no biological or DNA link to the child she carries. Under current Indian fertility guidelines, gestational surrogacy is the medically accepted route. Because every fertility journey is deeply unique, we encourage scheduling a detailed consultation with a fertility expert to evaluate your personal needs.

Biologically, the difference comes down to the origin of the ovum. In traditional surrogacy, the surrogate is the genetic mother because her own egg is fertilised with the intended father’s or donor’s sperm.
With gestational surrogacy, advanced IVF technology allows an embryo to be generated using the intended mother's or donor egg and transferred into the surrogate's womb. Here, the surrogate acts solely as the gestational host, without passing down any genetic traits or DNA to the child. In India, gestational surrogacy is standard medical practice. I always advise individuals and couples to speak directly with an experienced fertility physician for guidance tailored to their clinical situation.

The primary biological difference between the two forms of surrogacy centers on genetics. In traditional surrogacy, the surrogate provides both the egg and the womb, creating a direct biological and genetic bond between the surrogate and the baby.
In gestational surrogacy, the surrogate carries a pregnancy achieved through IVF using gametes from the intended parents or donors. Biologically, the surrogate provides the uterine environment to support fetal development, but contributes no genetic material. In India, gestational surrogacy is the recognized medical path under modern guidelines. If you are exploring third-party reproduction, please consult a fertility specialist for personalized medical counsel.
