Parental Acceptability of Artificial Womb Technology for Extreme Prematurity
A study of 30 parents found that a majority would accept participating in a first-in-human trial of artificial womb technology for 23-week gestational infants, driven by hope for better outcomes, though their willingness depends on transparent communication regarding risks and trial safeguards.

When a baby is born far too early, before the body is ready to breathe or regulate its own temperature, the medical world faces a profound and heartbreaking challenge. These infants, born before twenty-eight weeks of pregnancy, often require a neonatal intensive care unit, a high-tech environment where machines breathe for them and tubes deliver nutrients. While modern medicine has saved many of these tiny lives, the journey is fraught with danger, and the risk of long-term health issues remains high. For decades, doctors have worked within the limits of this external support, but a new idea has emerged from the laboratory: a way to continue the pregnancy outside the mother's body. This concept, known as artificial womb technology, envisions a fluid-filled chamber that mimics the womb, allowing an extremely premature infant to continue developing as if still inside the mother. The technology has moved from science fiction to animal trials, where it has successfully supported fetal lambs for weeks. Now, as scientists prepare to test this device in humans for the first time, a critical question arises: if this technology were available, would parents choose it for their own children?
To answer this, researchers at Duke University spoke with thirty parents, asking them to imagine a difficult scenario. They were told to picture a pregnancy where labor begins unexpectedly at twenty-three weeks, a point where survival is possible but uncertain and the risks of severe complications are high. The parents were presented with three choices for their baby: standard intensive care in a hospital, comfort care focused on making the baby comfortable without aggressive life support, or enrollment in a first-in-human trial for the artificial womb device. The researchers explained that the device would keep the baby in a liquid environment, connected to oxygen through the umbilical cord, without the baby ever taking a breath on its own. They showed the parents images of the technology, including a picture of a lamb in the system, to help them visualize what it might look like. The goal was not to predict the future, but to understand what parents value when facing such a terrifying decision and what information they would need to make a choice.
The results of these conversations revealed a surprising openness to the new technology. When faced with the hypothetical choice, nearly two-thirds of the parents said they would enroll their baby in the trial for the artificial womb. The primary reason for this choice was hope. Parents believed that keeping the baby in a fluid environment that mimics the womb might lead to better survival rates and fewer long-term health problems compared to the harsh reality of a hospital incubator. Many described the device as more natural, feeling that it allowed the baby to continue growing in the way nature intended, rather than fighting against the environment of a neonatal unit. For some, the device appeared more comfortable, free from the tangle of wires and tubes that often surround premature infants. Others expressed a deep trust in medical progress, believing that if the technology worked for lambs, it could work for humans, and some felt a desire to help future families by participating in the research.
However, the decision was not unanimous, and a significant portion of parents hesitated. About one-third of the participants chose standard intensive care, and a small number opted for comfort care. The most common reason for declining the trial was a fear of being the first. These parents were uncomfortable with the idea of their child being the very first human to test a new, unproven technology. They worried about unforeseen complications, such as a tube disconnecting or the machine failing, and they valued the decades of experience and proven track record of traditional intensive care. For some, the lack of human touch was a major barrier; they felt that a machine could not replace the warmth and connection of holding a baby or the reassurance of a doctor's hands. One bereaved parent, who had lost a child born prematurely, chose comfort care, highlighting that even among those with the most painful experience, there is no single path or preference.
The study also uncovered the specific questions parents would need answered before making a decision. They wanted clear data on survival rates and the likelihood of long-term developmental issues. They asked practical questions about how long the baby would stay in the device, what would happen if the treatment failed, and whether they could switch back to standard care. There was a strong desire to understand the science behind the device, including how the baby would be fed and how doctors would monitor its health without touching it. The researchers found that while parents were willing to consider this revolutionary approach, their trust depended entirely on transparency. They needed to know exactly what was known, what was unknown, and what safeguards were in place. The study suggests that for artificial womb technology to be accepted by families, the conversation must go beyond the science of the machine and address the deep emotional and practical needs of the parents, ensuring they feel informed and supported as they navigate the most difficult choices of their lives.
