Regulation of estrous cycle in hysterectomized albino rats by activation of follicular development.

ABSTRACT

Wistar strain albino rats were hysterectomized and the estrous cycle was compared with sham operated controls. Duration of estrous cycle in hysterectomized rats increased markedly with significant delay in the luteal phase and this was correlated to the inhibited follicular development of ovary. When these rats were treated with PGF2 alpha and PMSG and subjected to physical exercises, the estrous cycle was synchronised and the ovaries of such animals had active follicular development. Thus the deranged operation of sexual cycle in hysterectomized rats was regulated through physical exercises.
