Abstract
Introduction Thereiscurrently a lackofadequate information onthe mating,reproduction and the reproductive anatomy of the frugivorous bat Eidolon helvum. We, therefore, investigated their uterus during the non-pregnant and pregnant states for adequate information and comparison between the two states to ascertain what histological adaptations occur during pregnancy in relation to collagen and elastic ?bers. MaterialsandMethods Atotal of 47 femalebats (E.helvum) wereused, outof which 24 were pregnant and 23 were not. They were harvested on the Obafemi Awolowo University Campus. The animals were carefully screened, assumed to be presumably healthyandthensacri?cedbycervicaldislocation.Theleftandrightuterinelimbswith theuterinebodyandpartoftheplacentawere?xedin10%formalsaline,processedfor paraf?nembeddingandsectionedat5?mwitharotarymicrotome.Thesectionswere stained using Verhoeff-van Gieson stain to demonstrate collagen and elastic ?bers.
