Hysteroscopy is a minimally invasive procedure used to examine the inside of the uterus (uterine cavity). It is performed using a thin, lighted instrument called a hysteroscope, which is inserted through the cervix into the uterus.

The hysteroscope allows the doctor to clearly view the uterine cavity on a monitor and diagnose or treat abnormalities without making any external incisions. Hysteroscopy is commonly used in the evaluation and treatment of infertility and abnormal uterine conditions.
