Given a 27-day cycle, when is the expected date of ovulation based on a last menstruation date of April 12, 2014?

• A. April 25, 2014
• B. April 26, 2014
• C. May 25, 2014
• D. May 26, 2014

Answer: (A)

To determine the expected date of ovulation for a woman with a typical 27-day menstrual cycle, the calculation begins with the last menstrual period (LMP). Ovulation generally occurs about 14 days before the start of the next menstrual period. In this case, if the last menstrual period is on April 12, 2014, adding 27 days to this date gives the expected start of the next period, which would be May 9, 2014. To find the ovulation date, we subtract approximately 14 days from this date. Calculating this, we find that ovulation is likely to occur around April 25, 2014, which aligns with a common estimate that ovulation occurs approximately midway through the cycle. Therefore, selecting April 25, 2014, reflects a solid understanding of the ovulation timing within a typical menstrual cycle. Other choices are from dates outside the ovulation timeframe based on the standard cycle length and the provided LMP. Specifically, April 26 is too late after the calculated ovulation date, and May 25 and May 26 are much too late, as they fall well outside the typical ovulation timing. Thus, April 25 is indeed the correct and
