At what age is primary amenorrhea characterized by no menstruation in the absence of secondary sex characteristics?

Primary amenorrhea refers to the absence of menstruation in individuals by a certain age, specifically when there is also an absence of secondary sex characteristics, such as breast development or pubic hair. The ages noted in the choices reflect the typical milestones in the development of reproductive health.

According to medical standards, primary amenorrhea is typically diagnosed in individuals who have not experienced menarche by age 14 if secondary sex characteristics are absent. This is important because while some individuals may naturally begin menstruating later, the absence of secondary sex characteristics by this age strongly suggests an underlying issue that may need to be addressed.

Selecting age 14 aligns with these guidelines, as it underscores the necessity for further evaluation if menstruation has not occurred by this point without the presence of secondary sex characteristics. Identifying and addressing primary amenorrhea is crucial for reproductive health and can indicate potential hormonal or anatomical issues that require intervention.
