Inside STAT: Most IVF 'add-ons' rest on shaky science, studies find

When Sarah Chamberlin’s doctor suggested that a drug called Neupogen might help her become pregnant through IVF, she didn’t hesitate. After all, she and her husband had already been through five rounds of artificial insemination and two cycles of in vitro fertilization — none of which had led to pregnancies. And Neupogen, the doctor explained, would help Chamberlin’s immune system stop rejecting IVF embryos, which he called "genetically incompatible" with her. New research, however, finds little evidence that “add-ons” like Neupogen — which are not essential to IVF but have increasingly become available in the past four decades  — improve the chances of a healthy, full-term pregnancy, and some may actually reduce a woman’s chance of conceiving.
