To evaluate the function of the fallopian tube after a recanalization by endoluminal laser probe, 34 mature female New Zealand white rabbits have been separated into two groups. The group 1 (nb = 12) had for aim to validate the procedure of obstruction. In group 2 (nb = 22), we performed the recanalization six weeks after the obstruction. The female rabbits underwent a fertilization six weeks after the laser treatment. The results have been appreciated by the ratio nidation/ovulation. In group 1, we valided the procedure of obstruction. In group 2 twelve rabbits on thirteen have been fecundated in the treated tube.
