Unlike anovulation, where irregular menstrual cycles may hint to a problem, blocked fallopian tubes rarely cause symptoms.
A specific kind of blocked fallopian tube, called hydrosalpinx, may cause lower abdominal pain and unusual vaginal discharge, but not every woman will have these symptoms.
However,some of the causes of blocked fallopian tubes might lead to hints of a problem. For example, endometriosis and pelvic inflammatory disease may cause painful menstruation and painful sexual intercourse. But these symptoms don't necessarily point to blocked tubes.
