Hi Helen, HSG could possibly be recommended, but usually a good ultrasound scan can identify a swollen tube and laparoscopy is the only definitive way to confirm if it is present.
Also at the laparoscopy you can remove or clip off the tube if it is swollen to help improve the chances of IVF being successful.
We hope this helps answer your question. If you would like to discuss this matter further with our team, please do call us on 0161 300 2737 to discussing arranging a consultation.
