Robots lend a hand
Like artificial intelligence, robots can be a big help in the IVF lab. Columbia University Fertility Center recently became the first to use an articulated (ART) robot to handle precise and highly repetitive work.
“IVF, from the initial point, involves creating these special plates where embryos can grow, and you do that by making little droplets,” said Dr. Williams. “It’s very time-consuming to create tons of these little droplets for the embryos to grow.” Thus, the lab created a robot to help squirt drops of the media substance required to sustain embryos in a way that is 10 times more precise than that of a trained embryologist.
“It’s a win-win because you allow the robots to do things better than a human can and this allows the humans to do things that a robot just can’t do,” explained Dr. Williams. He and his team began using this technology in the beginning of November 2022.
Dr. Williams sees ART robots being used in many more parts of the fertility treatment journey along the way, like preparing eggs after they are retrieved and performing intracytoplasmic sperm injection (ICSI), with the robot injecting the sperm into the egg.
Launching with the plate making, said Dr. Williams, is a low stakes entry point for robotic technology in the lab. “It allows us to introduce robotics to automate and optimize each step along the way, but to do so in the safest possible way.”
Dr. Williams estimates that robots will have their hands on actual eggs and sperm in 5 years.
Updates in genetic testing
Currently, if a couple wants to have their embryos genetically tested, also known as preimplantation genetic testing, each embryo must be frozen, then a biopsy of that embryo is performed and sent to the lab.
“It takes time to get the results,” said Dr. Williams. “The whole time you’re waiting, you don’t know if you’re going to have any embryos that are transferable or if next month you’re going to have to do another IVF cycle.”
Columbia researchers recently developed a new in-house test that can determine if a fetus or embryo has the right number of chromosomes. This STORK (Short-read Transpore Rapid Karyotyping) can be performed without freezing embryos and sending them out, which Dr. Williams said can save couples money and time, as they won’t necessarily need to do a separate embryo transfer cycle and can transfer an embryo in the same cycle. “You can test in the morning and transfer in the afternoon,” said Dr. Williams.
The test is currently awaiting approval and will first be used to test miscarriage samples to see if embryos were genetically normal or not, which he said should cost around $200 vs. the $2,000 to $4,000 it can cost to have fetal tissue sent to the lab – and insurance doesn’t cover the procedure until after a second or third miscarriage.
This, said Dr. Williams, should be in the field in less than a year, and he estimates that the test will be used for fresh embryos in about a year and a half.
