Which statement best describes STRAW+10 staging system?

• A. STRAW+10 defines three main phases: reproductive, menopausal transition, postmenopause.
• B. STRAW+10 defines four main phases: premenopause, early transition, late transition, postmenopause.
• C. STRAW+10 is used to classify ovarian reserve only.
• D. STRAW+10 has no relevance to menopause staging.

Answer: (A)

The main idea tested is how STRAW+10 categorizes the menopausal aging process. STRAW+10 defines four distinct stages: premenopause, early transition, late transition, and postmenopause. Premenopause is when cycles are regular and ovarian function is typical. Early transition marks the start of menstrual changes with growing variability in cycle length and hormonal shifts. Late transition involves more pronounced irregularity and longer gaps between periods, signaling that end of reproductive years is near. Postmenopause follows the final menstrual period, with sustained low ovarian hormone levels and the end of natural cycling. This four-stage framework best captures the gradual progression of reproductive aging, including both early and late transitional phases, rather than grouping the transition into a single phase. STRAW+10 is specifically about staging menopausal aging, not about assessing ovarian reserve alone.
