What does 'amenorrhea' signify for women?

'Amenorrhea' refers specifically to the absence of menstrual periods in women. This condition can be classified into two types: primary amenorrhea, which occurs when a woman has never had a menstrual period by age 15, and secondary amenorrhea, which is when periods stop for three months or longer in someone who has previously had regular cycles.

Understanding the context is essential in differentiating amenorrhea from other menstrual-related terms. Regular menstrual cycles indicate normal menstrual health, while infrequent menses could point to irregularities but does not establish a complete absence. Excessive bleeding describes a different issue altogether associated with the volume of menstrual flow rather than its occurrence. Thus, the term amenorrhea is specifically concerned with the lack of menstrual periods, making the selection of this answer accurate.
