Vaginal atrophy evaluated by histological analysis


  • To evaluate vaginal morphological and histological changes in ovariectomized female rat, a relevant preclinical model of menopause
  • To evaluate the thickness of the vaginal epithelium
  • To examine the architecture and the cell shape of the vaginal epithelium
  • Useful for the evaluation of the effect of drugs developed for menopausal symptoms, including vaginal atrophy, vaginal dryness, lubrication difficulties or dyspareunia.

Summarized methodology:

Adult non-pregnant female Sprague-Dawley rats are ovariectomized bilaterally through a lumbar incision. The ovarian bundles are tied off with 3/0 polyester suture and the ovaries removed. The effectiveness of ovarian removal is checked under binocular microscope. The fascia and the skin are closed using 3/0 polyester suture. Two to four weeks after surgery, the vagina are collected and processed for histological and morphological analysis.


  • Vaginal weight
  • Thickness of the epithelium : surface area and number of epithelial layers
  • Architecture of the epithelium : shape and morphology of epithelial cells
