Fig. 1. The effect of repeated ovarian stimulation on estrous cycle in mice ovaries.
(A) The smear test was used to examine endometrial cells in OS and RS group mice. (B) The smear test validated the estrous cycle status of OS (n=6) and RS (n=6) groups mice. (C) Visual inspection was used to examine morphological changes in the uterus and ovaries of mice in OS and RS group mice. OS, once stimulation; RS, repeated stimulation.
