PURPOSE:- The objective of this study was to assess the effect of Totally extra-peritoneal inguinal hernia repair on testicular perfusion and testicular volume. METHODS: - After obtaining ethical clearance from institutional ethical committee, the present Prospective study was conducted on 48 male patients with unilateral inguinal hernia in a tertiary care hospital. RESULTS: - The study was conducted on 48 patients over a period of 2 years from august 2017 to august 2019 after meeting inclusion and exclusion criteria. Their mean age was 45.70 years (range 21-72 years). In our study comparison of preoperative and postoperative values at third and sixth month in the patients did not show any statistically signicant alteration in the variables studied like testicular volume (p-0.987) and blood ow perfusion parameters Peak systolic velocity (p-0.591); End Diastolic velocity (p-0.526); Resistance index (p-0.415). CONCLUSION: - No alteration in testicular volume and arterial ow over a six-month period was observed among patients who underwent laparoscopic extra-peritoneal surgical correction using polypropylene prosthesis for inguinal hernia
