The time taken for radio-opaque markers to pass through the intestine has been measured in 25 healthy men, and 18 healthy women in both the follicular and luteal phases of the menstrual cycle.

The mean values (2 standard deviations) for men and women in both phases of the menstrual cycle proved to be so similar that the results have been combined to provide a single normal range. These data for the normal range for retained markers (as assessed by p..
