Recommendations from a multi-study evaluation of proposed criteria for Staging Reproductive Aging
In 2001 , the Stages of Reproductive Aging Workshop ( STRAW ) proposed bleeding and endocrine criteria for defining the early and late menopausal transition stages . Based on expert consensus , STRAW recommended a shorter interval of amenorrhea than the commonly used 90-day amenorrhea criteria for late transition and a > 7-day change in cycle length for early transition . The ReSTAGE collaboration  used prospect i ve menstrual calendar data from four cohorts ( TREMIN , Melbourne Women 's Midlife Health Project , Seattle Midlife Women 's Health Study , and Study of Women 's Health Across the Nation ) to quantitatively evaluate STRAW 's recommendations . This empirical assessment supported the STRAW recommendations that ( 1 ) ≥60 days of amenorrhea be used to define the late menopausal transition and ( 2 ) that early transition is consistent with a persistent 7 or more day difference in length of consecutive cycles . Serum follicle stimulating hormone ( FSH ) values ≥40 IU/l was an independent marker of the transition and , when occurring together with a bleeding marker , increased prediction of final menstrual period . Such a FSH criterion could be incorporated into the STRAW paradigm to facilitate prediction of proximity of the final menstrual period
