Comparative Study on the Estimation of Estrous Cycle in Mice by Visual and Vaginal Lavage Method.

Introduction: Evaluation of estrous cycle in laboratory animals can be a useful measure of the integrity of hypothalamic-pituitary-ovarian reproductive axis. Assessment of vaginal cytology is crucial to assess the milieu and compare the endocrine status of animals among the experimental groups.

Aim: The present study was attempted to compare the estimation of estrous cycle by visual method and non invasive vaginal lavage method.
