Role of IVF
There is still the possibility that something about fertility issues, rather than IVF treatment, makes women more likely to develop borderline ovarian tumors.
"You could easily reason that the ovaries of the women in the IVF group are more resistant to pregnancy than the other subfertile [women with fertility problems] group. It could be that there is some connection between severity of infertility and risk for a tumor," says Joe Leigh Simpson, MD, a gynecologist and past president of the American Society for Reproductive Medicine.
The results of the Dutch study are also based on IVF treatments used before 1995. Today's IVF treatments are different. "Enormous changes have occurred in the last 10-15 years. It's not necessary to stimulate women's ovaries as heavily as we did at one time," Simpson says.
