Nasal mucociliary transport time was studied in nine healthy women over the menstrual cycle using the vegetable charcoal powder technique. Three measurements were made at different points of the cycle: during the early follicular phase, periovulatory phase and luteal phase. The mean transport times were 10.1 +/- 3.50, 5.1 +/- 2.08 and 7.5 +/- 3.28 minutes, respectively. Transit was significantly accelerated during the periovulatory phase (p less than 0.01), when the seric estrogens are at their highest level.
