How staging works
The STRAW system divides the transition by cycle behavior rather than age. Persistent variation of seven days or more marks early transition, a skipped stretch of sixty days marks late transition, and twelve months without a period defines menopause.
Understanding your result
- Regular cycles mean the reproductive stage continues
- Seven day variability signals early transition
- Sixty day gaps mark late transition, when symptoms often peak
- Twelve months without bleeding confirms postmenopause
Why staging helps
Each stage carries different priorities, from contraception still being relevant in early transition to bone protection taking center stage after the final period.
Symptoms at any stage
Hot flashes, sleep disruption and mood changes are treatable at every stage, so staging guides but never gates care.
