This experiment investigates CO 2 ‐laser‐induced histological effects on fallopian tubes obtained during hysterectomies in women. Tubal transversal sections were performed at isthmic and ampullar sites. Forty strips were available for histological study of the cut section area. The role of different parameters such as radiation power and beam fractionation (continuous versus pulsed) on tissue lesions was assessed. In tubal microsurgery, the CO 2 laser can be used as a scalpel with the predominant advantage of minimal tissular alterations. As a result of this study, our recommended parameters are the following: radiation power, 7–10 W; beam focalization zone, 0.2 mm; energy density, 20,000–35,000 W/cm 2 ; continuous operation; moving speed, 1 cm/s.
