List the three main phases defined by the STRAW+10 staging system.

• A. Reproductive, Menopausal Transition, Postmenopause
• B. Prepubertal, Reproductive, Postpartum
• C. Follicular, Ovulatory, Luteal
• D. Reproductive, Menopausal Transition, Postmenopause

Answer: (D)

STRAW+10 organizes reproductive aging into three main phases based on menstrual changes rather than age alone. The three phases are Reproductive, Menopausal Transition, and Postmenopause. In the Reproductive phase, cycles are regular and ovulatory with ongoing fertility. The Menopausal Transition covers the period of increasing cycle variability and eventual cessation of cycles, marking the approach to the final menstrual period. Postmenopause begins after the last menstrual period, continuing for life with at least 12 months of amenorrhea. The update merges the earlier separate early and late transition into one Menopausal Transition phase, reflecting the continuous nature of the changes. Other options describe puberty, postpartum states, or basic menstrual-cycle phases rather than aging stages, so they don’t fit STRAW+10.
