There is a robot working in IVF labs right now that most embryologists outside the US have not heard of yet. It is called APRIL – the ART Pipetting Robot for the IVF Laboratory and a peer-reviewed study published in Fertility and Sterility found it prepares embryo culture dishes ten times more precisely than a human doing the same job.

That is not a headline number pulled from a press release. It comes from a prospective randomised study at Columbia University Fertility Center ranked the number one fertility clinic in the United States by Newsweek comparing APRIL’s dish preparation against standard manual methods, using both mouse and human embryo outcomes as the measure.

Dr Zev Williams, who led the research and directs the Columbia fertility centre, put it plainly: “IVF requires extraordinary precision, but human hands introduce variability, no matter how skilled.”

That sentence is worth sitting with. It is not a criticism of embryologists. It is an honest observation about the physical limits of manual work at microscopic scale limits that affect every human in every lab, regardless of training or experience.

What APRIL actually does

APRIL is a liquid-handling robot built specifically for preparing the microdroplet culture dishes used to sustain embryos during development. It uses custom 3D-printed adapters and is enclosed to maintain sterility. The precision gain comes from consistent dispensing volume, timing, and environmental control removing the variability introduced by fatigue, technique differences between operators, and the unavoidable slight inconsistencies of manual pipetting across a long working day.

It does not select embryos. It does not perform ICSI. It does not make clinical decisions. It prepares the dishes and it does that one specific task with a consistency that human hands cannot match.

What this means practically

Columbia also developed the STAR system (Sperm Tracking and Recovery), which uses AI to identify viable sperm in men with infertility. Conceivable Life’s AURA platform, currently in pilot with early results showing 51% pregnancy rates automates broader parts of the IVF workflow. Overture Life’s DaVitri device handles egg freezing specifically and is preparing to launch in Europe.

None of these companies are positioning their technology as a replacement for embryologists. The framing across all of them is consistent: automation handles precision repetition, the embryologist handles judgement.

What is shifting is the definition of the embryologist’s role. As robotic systems absorb the tasks where human variance is a liability, the human contribution concentrates more fully in the areas where experience and adaptability actually matter reading a cycle that is not going to plan, making a call that no algorithm has been trained to make, being the person in the room when a family gets news.

The part worth watching from a UK perspective

These systems are largely US-based for now, with European launches at various stages. For UK fertility labs, the more immediate technology shift is AI-assisted embryo selection time-lapse imaging tools that support morphological grading decisions. These are already in use at a number of UK clinics and the evidence base is building, though large-scale outcome validation is still ongoing.

One thing that automation does not change and arguably makes more important as volumes increase is the quality of physical sample management. Cryogenic storage organisation, identification systems, handling protocols. A robotic system upstream does not compensate for a storage error downstream. The fundamentals still matter.
