Abstract
(1) Methods and experiments are described for testing the length of fertility of the sperms in the male and female tracts of rabbits.
(2) The sperms may retain their fertility in the male tract up to 38 days, but in the female tract only up to 30 hours.
(3) In cases where the sperms had remained in the female tract for 24-30 hours before ovulation small litters were frequently produced; it is suggested that this is due to the end point of the vitality of the sperms falling within the limits of time during which the process of ovulation occurs.
(4) The bearing of these results on problems of fertility and sterility is discussed.
