What is the average amount of blood lost during a menstrual cycle?

The average amount of blood lost during a menstrual cycle is typically around 80 milliliters, although some sources may provide estimates that can range up to 120 milliliters. This quantity reflects the normal range for menstruation in individuals with regular cycles. Menstrual blood loss can vary based on individual factors such as age, hormonal balance, and overall health. While the average is cited around 80 ml, it is important to understand that this number encompasses a range of normal variability, and higher amounts may occur in cases of heavy menstrual bleeding or other conditions.

This context clarifies why the other amounts listed are generally considered outside the normal range; they either exceed what has been observed in most assessments of menstrual blood loss or may be associated with abnormal conditions rather than typical menstrual cycles.
