Question

Get out your calculators! This week's discussion question is as follows: If a girl started menstruating at age 12 , went through menopause at age 52 , was pregnant twice and carried the child to term during that time frame, how many periods would she normally have in her lifetime?

Answer 1

A woman would typically have 520 periods in her lifetime.

Step-by-step explanation:

A typical menstrual cycle averages 28 days in length but may vary normally from 21 to 45 days. The average menstrual period is five days long but may vary normally from two to seven days. Based on this information, we can calculate the number of periods a woman would have during her reproductive years.

Let's assume that the woman in question started menstruating at age 12 and went through menopause at age 52. This gives us a total of 40 years of menstruation (52 - 12 = 40).

If we consider an average menstrual cycle of 28 days and an average menstrual period of 5 days, we can calculate the number of periods within a year: 365 divided by 28 equals approximately 13 cycles in a year.

Therefore, the number of periods in 40 years would be: 40 years multiplied by 13 cycles per year, which equals 520 periods in a woman's lifetime.
