About 54.3% of the infertile females has subtle distal fallopian tube anomalies, which are non-obstructive anomalies outside the fallopian tube. These include fimbria agglutinations, tubal phimosis, Morgagni hydatids cysts, tubal sacculation, tubal diverticula, accessory tubes, and accessory fimbrial ostia. Unexplained infertility refers to the absence of a clear reason for a couple's infertility and females' inability to conceive after at least 12 cycles of unprotected regular sexual activity. Traditional diagnostic testing does not necessarily indicate no cause for infertility. Laparoscopy can reveal undetected pelvic diseases correlated to subfertility, and surgically correction of these abnormalities can have a therapeutic effect on conception. Applying this management protocol can minimize the use of procedures and reduce costs if IVF is not readily available.

AIM OF THE WORK:
The aim of this study was to investigate the prevalence of subtle fallopian tube abnormalitiesdetected during laparoscopy in women with otherwise unexplained subfertility.

PATIENTS AND METHODS:
This observational cross-section study was conducted on 120 infertile women who were originally diagnosed as having unexplained infertility and scheduled for diagnostic laparoscopy at the endoscopy unit at El Shatby University Hospital.All patients were subjectedpre-operatively to complete history taking, complete general and pelvic examination and checkedfornormalTVUS, infertility hormonal assay, andHSG. Upon laparoscopy, correlation with HSG considering tubal patency, andevaluate fallopian tubes for unilateral or bilateral presence of subtle fallopian tube anomalies.
