New Time-Lapse IVF Technology Improves Chances for Prospective Parents
A recent study suggests that a new time-lapse monitoring technique can improve success rates for in vitro fertilization patients. Led by Dr. John Zhang, M.D., director of New York City's New Hope Fertility Center, the study found that time-lapse monitoring – continuous observation of embryos in undisturbed culture with strict environmental control – can be used at the preimplantation phase of genetic screening to help improve the chances of an IVF patient conceiving.
When used alongside more conventional techniques, the study further showed a significant impact on IVF success rates. The blind study enrolled patients with a mean age of 36 and compared sets of eggs (each from the same woman) cultured by time-lapse monitoring with those cultured in a normal incubator. When implanted, the pregnancy rate was 71 percent for the time-lapse eggs and 45 percent for eggs incubated normally. This translated to a sustained and ongoing pregnancy rate of 69 percent for those using the time-lapse system, versus 41 percent for those using the conventional method.
