An experimental fertility method called intralipid infusion may help boost fertility treatments. But the procedure, more commonly practiced in the U.K., does not have a wide range of support in the United States.
Intralipid infusion involves a woman receiving an IV solution consisting partly of soybean oil and egg yolk. This procedure is given in conjunction with a fertility procedure such as IVF to aid the process of embryo implantation.
Though the procedure lacks comprehensive evidence-based studies to support it, its users believe its effect is a result of decreasing the activity of natural killer immune cells. By regulating these cells, proponents of the procedure allege that the risk for miscarriage is decreased.
Many American fertility doctors are leery about performing a procedure that is not supported in the medical literature.
Dr. Michael Murray, director of reproductive endocrinology and infertility at Northern California Fertility Medical Center, believes that the infusion is just another example of patients “…grasping at straws for a solution to their recurrent miscarriages.”
Scientific studies that have tested the procedure have given mixed results, with no study strongly supporting intralipid infusion as a treatment to prevent miscarriage.
