The time course of ovum transport was determined in cycling guinea pigs. The occurrence of ovulation was determined in assessing changes in vaginal cytology. The day of the postovulatory leukocyte influx was considered day 1 of the cycle. Ovum transport in guinea pigs is characterized by a relatively long sojourn in the ampulla, followed by rapid transport through the isthmus. This pattern is similar to that seen in women and subhuman primates and different from the pattern in rabbits.
