Research Question: To evaluate the findings of outpatient transvaginal hydrolaparoscopy (THL) in comparison with diagnostic laparoscopy combined with chromopertubation in subfertile women.
Design: In a retrospective study in four large teaching hospitals, all subfertile women who underwent a THL and a conventional laparoscopy as part of their fertility work-up in the period between 2000 and 2011 were studied. Findings at THL were compared with findings at diagnostic and therapeutic laparoscopies.
