Concentration of sRAGE in follicular fluid is several-fold higher compared to serum and most other biological fluids investigated until this time. It supports the hypothesis that mammalian ovulation can be compared to an inflammatory event.
A significant negative correlation of serum sRAGE with the yield of follicles and oocytes, together with the high follicular sRAGE levels, in particular in women who conceive after the IVF, could be explained by the essential outflow of sRAGE to the follicular compartment.
