Which term describes the cessation of menstrual periods for 12 months or more?

• A. Dysmenorrhea
• B. Menopause
• C. Oligomenorrhea
• D. Menorrhagia

Answer: (B)

Menopause is the term that describes the cessation of menstrual periods for 12 months or more, marking the end of a woman's reproductive years. This occurs due to the natural decline in the production of hormones like estrogen and progesterone by the ovaries, leading to the absence of menstruation. Menopause typically occurs between the ages of 45 and 55 and is a normal biological process, signifying that a woman can no longer conceive.

Dysmenorrhea refers to painful menstruation and is not related to the cessation of periods. Oligomenorrhea describes infrequent menstrual periods, which does not indicate a complete stop of menstruation. Menorrhagia is characterized by abnormally heavy or prolonged menstrual bleeding, indicating issues within the menstrual cycle rather than its cessation. Thus, menopause is distinctly identified by the complete and permanent halt of menstrual cycles, confirming the choice as the correct answer.
