Material and Methods: One hundred patients who underwent HSG during the infertility work-up and were found to have unilateral PTO were included in the study. Forty patients who accepted our proposal of expectant treatment or intrauterine insemination (IUI) were excluded from the study. The remaining 60 patients underwent a second HSG in the next cycle, and the results were compared with the results of the first HSG. Results: Bilateral tubal patency was detected in 35 of 60 patients who underwent a second HSG for PTO confirmation (58.3%). In the remaining 25 patients, unilateral PTO persisted (41.6%). Discussion: In patients with unilateral PTO in the first HSG, performing a second HSG before planning further examination with laparoscopy or hysteroscopy provides bilateral tubal patency in more than half of the patients.eninfo:eu-repo/semantics/openAccessSecond HSGProximal Tubal ObstructionInfertilityArticle10.4328/ACAM.20870126212413WOS:000729254300001N/A
