Background: A variety of factors, including tubal blockage, cause infertility, a global problem. As a result, the purpose of this study was to look at the most common tubal irregularities. Methodology: A descriptive longitudinal study was undertaken in Khair Alelag private hospital in El-Obeid, North Kordofan State, Sudan, from January to December 2023. We included approximately 60 individuals who presented for a hygrosalpingogram (HSG) evaluation. Results: According to our findings, half of the study group 30(50%) has a history of PID, with 17 (57%) having tubal obstruction, either bilaterally (7%) or unilaterally (10%). Those without a history of PID (12%) have tubal obstruction, either bilaterally (3%) or unilaterally (9%). 12 (20%) have a history of uterine or tubal surgery, all with tubal obstruction; 8 (13%) have unilateral tubal obstruction; and 4 (7%) have bilateral tubal obstruction. Conclusion: Tubal blockage is common in Sudan, and it may contribute to the country's high rate of infertility. Unilateral tubal blockage is the most prevalent form.
