From Assisted Hatching to Embryo Glue, Most IVF ‘Add-ons’ Rest on Shaky Science, Studies Find

November 6, 2019

(STAT News) – In the 40 years since the world’s first “test tube baby,” fertility clinics have cooked up nearly three dozen such “add-ons,” or supplementary procedures. Like immune therapy for supposed genetic incompatibility, they’re not essential to IVF. Instead, clinics offer procedures such as “assisted hatching” and “embryo glue” and “uterine artery vasodilation” as purportedly science-based options that increase the chance of having a baby. Except there is little to no evidence that the vast majority of IVF add-ons do any such thing, conclude four papers published on Tuesday in Fertility and Sterility, the journal of the American Society for Reproductive Medicine.
