What marks the postmenopausal period?

• A. Interval before menopause
• B. Immediately after menarche
• C. Time after final menstrual period
• D. During lactation

Answer: (C)

The postmenopausal period is defined by what happens after the final menstrual period occurs. Once menstruation ceases permanently due to waning ovarian function, a woman enters postmenopause. The final menstrual period is the event that marks this transition, and the time thereafter is when estrogen levels remain low and long-term effects—like bone and cardiovascular changes—can become more evident. Perimenopause is the transitional phase leading up to this point, characterized by irregular cycles, while the other options refer to puberty (the onset of menstruation) or a postpartum lactation state, not menopause.
