Texas Tech researchers develop safer approach to in vitro fertilization

Researchers at the Texas Tech University Health Sciences Center (TTUHSC) have invented a new method for selecting viable embryos for in vitro fertilization (IVF).

Developed by TTUHSC researchers Samuel Prien and Lindsay Penrose, the patented technology determines the viability of an embryo by applying a non-invasive grading based on factors such as gravity, density, and estimated weight. According to Prien and Melrose, the method has been shown to recover 100% of embryos and is between 90-100% accurate in its selection.

“Our device is based upon a very simple concept of buoyancy,” says Prien. “The healthy embryo should have a certain kind of chemistry and so much fluid content, so if you put it in a buoyancy chamber, it should drop at a given rate. If it’s not healthy, it should either drop faster or slower.”

The novel method could assist couples who have difficulty getting pregnant, but without any direct sampling or risk to the embryo. By contrast, current methods such as preimplantation genetic testing involve risky procedures that can damage or even destroy the embryo.

“We were trying to find something where the risk to the embryos was going to be absolutely minimal, because sometimes you’re talking about a patient that may only have three embryos,” Prien adds. “The holy grail of what we’ve been trying to do is come up with a way of evaluating the embryo non-invasively so that we’re not doing anything to the embryo; we’re just getting back an answer.”
