What is uterotubal insufflation?

Uterotubal insufflation is a medical procedure used primarily to assess the patency (openness) of the fallopian tubes in women. During the procedure, a gas, typically carbon dioxide, is introduced into the uterine cavity and fallopian tubes through the cervix. This allows for the evaluation of any blockages or abnormalities that might affect fertility. It is often performed as part of a fertility workup.
