Which of the following is NOT a STRAW+10 phase?

• A. Reproductive
• B. Menopausal Transition
• C. Postmenopause
• D. Luteal phase

Answer: (D)

STRAW+10 describes stages of reproductive aging based on how ovarian function and menstrual cycles change over time. The main categories are Reproductive (regular cycles with preserved ovarian function), Menopausal Transition (perimenopause with increasing cycle variability and hormonal shifts), and Postmenopause (after menopause with low estrogen). The luteal phase, however, is a specific part of the menstrual cycle that occurs after ovulation and is ruled by progesterone, lasting about two weeks. It’s a normal cycle phase, not a long-term aging stage. Because STRAW+10 is about aging and transitions in ovarian function rather than the routine cycle phases, the luteal phase isn’t a STRAW+10 phase.
