Key Terminology in Surrogacy: A Simple Guide to Fertility and Surrogacy Terms
Surrogacy involves medical procedures, legal requirements and decisions about pregnancy and parenthood. Understanding the terminology can help intended parents, surrogate mothers and families follow discussions with fertility specialists and legal professionals.
This glossary explains common surrogacy and assisted reproductive technology (ART) terms in straightforward language, with particular attention to the Indian regulatory context.
Key Surrogacy Terms Explained
1. Surrogacy
A reproductive arrangement in which a woman carries and gives birth to a child with the intention that the child will be raised by the intending parent or parents, subject to applicable law.
2. Surrogate Mother
The woman who carries a pregnancy under a surrogacy arrangement. In India, the term is used within the framework of the Surrogacy (Regulation) Act, 2021 and associated rules.
3. Intending Couple
A couple who intends to become parents through surrogacy. Eligibility and documentation requirements are determined by the applicable legislation and rules.
4. Intending Woman
A woman who intends to become a parent through surrogacy, as defined and regulated under the applicable Indian legal framework.
5. Gestational Surrogacy
A type of surrogacy in which an embryo created through IVF is transferred to the surrogate’s uterus. The surrogate does not provide the egg used to create that embryo.
6. Traditional or Genetic Surrogacy
A term used internationally for an arrangement in which the woman carrying the pregnancy also provides the egg. This differs from gestational surrogacy. Do not assume that a terminology label means an arrangement is legally permitted in India.
7. Altruistic Surrogacy
Under India’s statutory framework, altruistic surrogacy excludes remuneration, fees or other monetary incentives to the surrogate mother, while allowing prescribed medical expenses, specified expenses and insurance coverage as provided by law.
8. Commercial Surrogacy
A surrogacy arrangement involving payment or reward beyond what the law permits. Commercial surrogacy is prohibited under India’s Surrogacy (Regulation) Act, 2021.
9. Assisted Reproductive Technology (ART)
Medical techniques involving the handling of sperm, oocytes or embryos outside the human body, as defined in the ART (Regulation) Act, 2021. IVF is a commonly used ART procedure.
10. IVF (In Vitro Fertilisation)
A fertility treatment in which eggs and sperm are brought together in a laboratory to achieve fertilisation. An embryo may then be cultured for possible transfer or cryopreservation.
11. ICSI (Intracytoplasmic Sperm Injection)
A laboratory technique in which a single sperm is injected directly into an egg. It may be used in selected IVF cycles based on clinical indications.
12. Embryo
An early stage of development after fertilisation. In IVF, embryos are assessed in the laboratory before a decision about transfer or freezing is made.
13. Embryo Transfer (ET)
A procedure in which an embryo is placed into the uterus. In gestational surrogacy, the embryo is transferred to the surrogate’s uterus.
14. Oocyte
An immature female reproductive cell, commonly called an egg cell. The term is frequently used in fertility treatment and laboratory records.
15. Gametes
Reproductive cells: sperm in males and oocytes (eggs) in females. Their use in treatment is subject to clinical consent and applicable regulations.
16. Donor Gametes
Eggs or sperm provided by a donor for use in fertility treatment. Whether and under what circumstances donor gametes may be used in a surrogacy arrangement depends on current law, rules and the relevant approvals.
17. Cryopreservation
The freezing and storage of reproductive material, such as embryos, eggs or sperm, for possible future use under appropriate clinical and legal requirements.
18. Frozen Embryo Transfer (FET)
A treatment cycle in which an embryo that was previously frozen and stored is thawed and transferred to the uterus.
19. Endometrium
The inner lining of the uterus. Its thickness and appearance may be assessed during fertility treatment to help plan the timing of embryo transfer.
20. Implantation
The process by which an embryo attaches to and begins to embed in the uterine lining. Implantation is an important early step in establishing a pregnancy.
21. Beta-hCG
A hormone measured in blood tests to help detect pregnancy. A clinician may interpret the result alongside the timing of embryo transfer and follow-up testing.
22. Ultrasound Confirmation
Ultrasound assessment used during early pregnancy follow-up to evaluate the pregnancy’s location and development. The timing and findings should be interpreted by the treating clinician.
23. Medical Indication
A medical reason considered relevant to treatment or surrogacy. Under Indian law, surrogacy is subject to statutory conditions and certification requirements; a clinician or authority must assess the individual circumstances.
24. Counselling
Professional support intended to help participants understand the medical, emotional, ethical and practical aspects of treatment and surrogacy.
25. Informed Consent
A voluntary decision made after receiving understandable information about the proposed procedure, relevant risks, alternatives and other material considerations.
26. ART Clinic
A facility that provides assisted reproductive technology services and is regulated under the ART (Regulation) Act, 2021 and applicable rules.
27. Surrogacy Clinic
A clinic providing surrogacy-related services within the regulatory framework. Registration and compliance requirements apply under the relevant legislation and rules.
28. Appropriate Authority
The authority designated under the relevant legislation to carry out specified regulatory functions, which may include registration, oversight and enforcement.
29. National ART & Surrogacy Registry
The national online registry associated with the Department of Health Research, Ministry of Health and Family Welfare, which maintains records relating to ART clinics, ART banks and surrogacy clinics.
30. Surrogacy (Regulation) Act, 2021
Indian legislation establishing the regulatory framework for surrogacy, including the constitution of boards, appointment of appropriate authorities and regulation of the practice and process of surrogacy.
Frequently Asked Questions (FAQs)
1. What does surrogacy mean?
Surrogacy is an arrangement in which a woman carries and gives birth to a child with the intention that the child will be raised by the intending parent or parents, in accordance with applicable law.
2. What is the difference between a surrogate mother and an intended parent?
The surrogate mother carries the pregnancy. The intended parent or parents intend to raise the child after birth, subject to the legal framework governing the arrangement.
3. What is gestational surrogacy?
It is a form of surrogacy in which an embryo created through IVF is transferred to the surrogate’s uterus, and the surrogate does not provide the egg.
4. Is traditional surrogacy the same as gestational surrogacy?
No. In traditional or genetic surrogacy, the carrier also provides the egg. In gestational surrogacy, the pregnancy follows embryo transfer and the carrier does not provide the egg.
5. What is altruistic surrogacy?
In India, it is a legally defined arrangement that excludes remuneration or monetary incentives to the surrogate, while allowing expenses and insurance as prescribed by law.
6. Is commercial surrogacy permitted in India?
