What is the expected duration of the early menopausal transition according to STRAW?

• A. 2-5 years
• B. 6-10 years
• C. 1-2 years
• D. 5-7 years

Answer: (A)

During the early menopausal transition, the timing of cycles becomes increasingly irregular as ovarian function declines. In STRAW staging, this phase is defined as lasting about 2 to 5 years before the final menstrual period. Hormonal changes begin, with rising FSH and greater month-to-month variability in cycle length, but menses still occur. That’s why 2-5 years is the best answer—it matches the STRAW-defined window for the early transition. Shorter periods (1-2 years) align with the late transition, while longer spans (6-10 or 5-7 years) exceed the standard duration attributed to the early transition.
