Recovery of human sperm from the fallopian tubes after natural insemination have been studied in sixty women; out of these, thirty cases were fitted with the Lippes loop, type C, for at least six months. The mean sperm count/high power field (HPF X 400) and percentage of motile sperm in the cervical mucus in both control and Lippes loop groups showed no significant differences. No sperm were recovered from the fallopian tubes of the Lippes loop group, while fourteen control cases had a positive recovery of sperm from the tubal washings. The mean number of white blood corpuscles in the tubal washings of Lippes loop-fitted cases was found to be significantly higher than in control cases. The phagocytic capacity of these cells may explain the low incidence of sperm recovered from the fallopian tubes in such cases.
