Biometric studies on the uterine tube of buffalo

Abstract

The study was conducted in both the left and the right uterine tubes of 33 buffaloes. The difference between the length
of left and right tubes was not significant. The infundibulum was the shortest segment. Of the remaining length, the initial
'U' shaped (hair pin loop) portion of the ampulla constituted 33.410/0, the tortuous ampulla 42.22% and the isthmus
24.37%. The ratio between the lengths ofthe ampulla and the isthmus was approximately 3: 1. The tubal length increased
during follicular phase. The formaline fixation evidenced a significant (P < 0.05) shrinkage (7.29%) in tubal length. The
maximum lumen diameter of the tube in the ampulla near infundibulum (4.81 ± 0.52 mm), gradually decreased to a minimum (0.55 ± 0.01 mm) in the isthmus. The tubal wall was thinnest (0.54 ± 0.05 mm) in the middle of the ampulla and thickest (0.90 ± 0.06 mm) in the isthmus. The mean values in respect of lengths, outer diameter, lumen diameter and the wall thickness differed significantly (P < 0.05) between the segments.
