Abstract: Congenital anomalies and acquired diseases of the uterus cavity may interfere with normal implantation and placentation that may lead to infertility and pregnancy loss. Hysteroscopy is considered the“gold standard” investigation for assessment of the uterine cavity，with the ability to treat uterine pathology in infertile patients. It also improves pregnancy outcome singnificantly. Hysteroscopy was even regarded as one of assisted reproduction technique by some authors. But the value of hysteroscopy as a routine approach in the management of infertile women is a matter of debate. Hysteroscopic tubal cannulation should be considered as a treatment option for women with proximal tubal obstruction because the treatment improves the chance of pregnancy. ART combineded with hysteroscopy requires further investigation. With the advantage of direct visualization，amplification，“see and treat”，and minimal invasion，hysteroscopy plays an more important role in infertility.
