Hello, welcome to HCM, I am Dr. Das.
Firstly, it is unnatural to interpret a HSG
report different at different times.
If there is a blockage in one / two tubes, then you have to be get operated. Because, if there is blockage, then fertilization can not take place and this may lead to infertility
A simple procedure is done for this disease - the blockage is tried to open by introducing air.
One important point is , after doing HSG, the blockage sometimes get opened.
So, consult with a gynaecologist for further management as I previously told.
