Traditionally, a diagnosis of unexplained infertility is established only when all standard clinical investigations yield normal results. When tubal patency has been established by hysterosalpingography (HSG), laparoscopy has been suggested as a mandatory step to preclude the existence of peritubal adhesions and endometriosis as causes of infertility. In women without ...
