Materials   and   Methods:   The   study   focused   on   morphological   study   of   the    fallopian   tube,   the   specimens   were   divided   in   three   age   groups   (0   to   13   years,   14 to 49 years and ≥50 years) with 10 specimen each group. Results: The   average   length   of   the   fallopian   tube   was   found   to   be 7.89   cm   in   left   and   7.65   cm,   in   right,   10.5   cm   in   left   and   10.27   cm   in   right   and   9.87   cm   in left   and   9.57cm   in   right      respectively,   while   the   average   outer    diameter   of   left   and   right   side   were   at   isthmus   3.01   mm   and   2.85   mm,   6.87   mm   and   6.05   mm and   6.18   mm   and   5.33   mm   respectively,   average   outer   diameter   of   left   and   right   side   were   at   ampulla   4.78   mm   and   4.43   mm,   10.56   mm   and   9.25   mm   and 9.24   mm   and   8.23   mm   respectively,   average   outer   diameter   of   left   and   right   side   were   at   infundibulum   were   3.63   mm   and   3.44   mm,   9.39   mm   and   8.24   mm and 7.69 mm and 7.02 mm respectively in different age groups. Conclusion:   The   length   and   outer   diameter   showed   significant   difference   in   right   and   left   side   and   in   different   age   groups.   Knowledge   of   normal   values might be helpful in different disease condition of the fallopian tube.
