What is the term for the natural cessation of menstruation, often accompanied by biological changes?

The term for the natural cessation of menstruation is menopause. This biological transition typically occurs in women between the ages of 45 and 55, marking the end of reproductive capability. During menopause, the ovaries produce less estrogen and progesterone, which leads to various physical changes and symptoms, such as hot flashes, mood changes, and changes in sexual function.

Understanding the context of menopause is important, particularly in relation to other terms. Menarche refers to the first occurrence of menstruation, signaling the beginning of a woman's reproductive years, while oligomenorrhea describes infrequent menstrual periods, which is not associated with the cessation of menstruation. The menstrual cycle simply refers to the regular monthly cycle of hormonal and physiological changes that occur in preparation for a potential pregnancy, which also does not indicate the cessation of menstruation. Therefore, menopause is the most accurate term describing the natural end of menstruation and its accompanying biological changes.
