New standard for PCOS diagnosis

PCOS may be over-diagnosed by new, more sensitive ultrasounds.

A new study by French researchers suggest the diagnoses for polycystic ovary syndrome (PCOS) may be outdated.  The old criterion: more than 12 follicles per ovary, detected with ultrasound, may no longer be valid given new tools.  In their study of 240 women, Dewailly et al. found that a serum anti-Mullerian hormone (AMH) level of more than 5 ng/ml is much more predictive of polycystic ovary morphology than even a follicle number of greater than 19.

This new tool  is less expensive to perform and would be available to a greater variety of women seeking diagnosis for infertility or mentrual disorders.
