Revisiting India’s Ultrasound Laws

UPSC Syllabus: Gs Paper 2- Issues relating to development and management of Social Sector/Services relating to Health.

Introduction

India’s Pre-Conception and Pre-Natal Diagnostic Techniques (PCPNDT) Act, 1994 was enacted to prevent prenatal sex determination and protect the declining child sex ratio. However, advances in portable ultrasound and artificial intelligence (AI) have expanded the medical use of ultrasound beyond obstetrics, particularly for early diagnosis in rural areas. This has raised important questions about whether the existing regulatory framework continues to balance the objectives of gender justice and accessible healthcare.

PCPNDT Act: Background, Objectives and Key Provisions

1. Historical Need for the Law: The spread of amniocentesis and ultrasound during the 1970s–1990s enabled prenatal sex determination in a society with a strong preference for sons. This led to widespread sex-selective abortions.
2. Objectives of the PCPNDT Act: The Act was enacted in 1994 to prohibit prenatal sex determination and prevent the misuse of diagnostic technologies. It also sought to address gender discrimination and protect the declining child sex ratio while fulfilling India’s commitments to gender equality.
3. Regulation of Ultrasound Services: The Act requires all genetic clinics, ultrasound centres and laboratories to be registered. It prohibits the disclosure of the foetus’s sex and prescribes strict monitoring, record keeping and penalties for violations.
4. Strict Control over Ultrasound Machines: Ultrasound machines can only be purchased by registered centres after government approval. Manufacturers must verify buyers, maintain transaction records and ensure that machines remain at their registered locations.
5. Protection of Gender Equality: The law recognises that preventing sex selection is essential to protect the dignity and equal worth of girls before birth. At the same time, it is not intended to weaken safe abortion access or women’s reproductive rights.

Achievements of the PCPNDT Act

1. Established a Strong Regulatory Framework: The Act created a nationwide legal system to regulate ultrasound technology, monitor diagnostic centres and prohibit prenatal sex determination. It made misuse of ultrasound for sex selection a punishable offence.
2. Improvement in Sex Ratio at Birth: India’s sex ratio at birth has gradually improved after the introduction of the Act. However, available evidence does not conclusively establish that this improvement resulted only from the law, as education, urbanisation and changing social attitudes also played important roles.
3. Expansion of Monitoring Mechanisms: The number of registered diagnostic centres increased from 49,544 (March 2014) to 98,595 (June 2025). This reflects a significant expansion of the regulatory system governing ultrasound services.
4. Reinforced Gender Equality: The Act recognised that sex-selective abortion is rooted in gender discrimination rather than medical practice alone. It established an important legal safeguard against practices that deny equal value to girls before birth.

Limitations of the Existing Framework

1. Limited Success in Eliminating Sex Selection: Illegal prenatal sex determination continues despite decades of prohibition. Crackdowns, including an organised racket uncovered in Karnataka in October 2025, show that such activities continue through informal networks and portable devices.
2. Enforcement Focuses More on Compliance than Outcomes: Implementation is largely measured through registrations, inspections, machine seizures and legal cases instead of actual prevention of sex selection. Around 68% of reported violations were procedural, showing that paperwork often receives greater attention than criminal misuse.
3. Fear among Genuine Healthcare Providers: Strict penalties, complex documentation and the risk of machine seizure have created fear among doctors and hospitals. Even minor clerical mistakes can result in legal action, discouraging the wider use of ultrasound for legitimate medical care.
4. Unintended Social Consequences: Where son preference continues, families with a first-born girl often have more children in the hope of having a son. Studies associate this with a 25% higher child mortality among first-born girls, reduced investment in health and education, and greater pressure on poorer rural households.
5. Law Alone Cannot Change Social Norms: Evidence from India and the Indian diaspora in countries such as the United Kingdom and Australia shows that son preference can persist despite strict regulation. This highlights that legal restrictions alone cannot eliminate deep-rooted gender bias and must be supported by broader social change.

Technological Advances and the Need for Reform

1. Changing Nature of Ultrasound Technology: The Act was framed when ultrasound was mainly used for obstetric imaging. Today, ultrasound is widely used in emergency medicine, trauma care, anaesthesia, cancer diagnosis and other clinical specialties, requiring a more differentiated regulatory approach.
2. Portable Ultrasound Can Improve Rural Healthcare: Portable and handheld ultrasound devices now make it possible to provide diagnostic services closer to patients’ homes. This can improve early detection of diseases such as breast cancer, especially in rural areas where nearly 70% of India’s population lives.
3. Current Law Has Not Kept Pace with Technology: The PCPNDT Act treats the movement of ultrasound machines outside registered centres as a serious offence. As a result, portable devices that can safely support community healthcare remain largely unavailable for legitimate medical use.
4. Same Rules for Different Medical Uses: Modern high-frequency linear probes used for breast cancer and other superficial conditions cannot determine foetal sex. Yet they are regulated under the same provisions as obstetric ultrasound, limiting access to essential diagnostic services.
5. Growing Role of Artificial Intelligence (AI): AI-enabled ultrasound systems can assist in image acquisition, interpretation and automated reporting. Such technologies can support purpose-specific diagnosis while reducing the possibility of misuse for prenatal sex determination.
6. AI Can Strengthen Early Cancer Detection: A pilot study found that AI-assisted portable ultrasound accurately identified all confirmed breast cancer cases, even when scans were performed by people with limited training. This can help frontline health workers identify suspicious cases and refer patients for timely treatment.
7. Importance for Rural Cancer Care: Unlike many Western countries that rely mainly on mammography, India can expand early diagnosis through community-based ultrasound because it requires fewer resources and can improve access in underserved areas.

The Way Forward

1. Separate Obstetric and Non-Obstetric Ultrasound: The regulatory framework should distinguish ultrasound used for pregnancy from ultrasound used in emergency care, trauma, anaesthesia, cancer diagnosis and other medical conditions. This will reduce unnecessary restrictions on legitimate healthcare services.
2. Legalise Community-Based Diagnostic Services: The Act should permit community-based ultrasound using high-frequency linear probes, as these cannot determine foetal sex. This can improve access to early diagnosis, particularly in rural and underserved areas.
3. Adopt Risk-Based Regulation: Portable ultrasound devices should be regulated through training standards, device registration, digital records and random inspections instead of treating machine mobility itself as the main risk. This can improve compliance while supporting wider healthcare access.
4. Modernise Monitoring Systems: Paper-based compliance should be replaced with secure digital systems such as encrypted image logs, machine-use records, geotagged scans and tamper-resistant data storage. These measures can improve monitoring without creating unnecessary administrative burdens.
5. Evaluate the Law Using Better Evidence: A national assessment should examine how much improvement in the sex ratio is due to the Act and how much results from education, urbanisation, fertility decline and changing social attitudes. Public reporting should focus on convictions, offence types and trial outcomes instead of only inspections and registrations.
6. Update the Law for Emerging Technologies: The Act should permit community-based ultrasound using high-frequency linear probes and include provisions for AI-enabled ultrasound systems that are designed to prevent foetal sex determination or disclosure.

Conclusion

The PCPNDT Act remains an essential safeguard against sex-selective practices, but its regulatory framework should evolve with changing medical technologies. India needs a balanced, risk-based approach that continues to prevent misuse while expanding access to safe, affordable and community-based diagnostic services. Such reforms can strengthen both gender justice and public healthcare.

Question for practice:

Evaluate the need to reform India’s PCPNDT Act in light of advances in ultrasound technology and changing healthcare needs.
