Abstract: Exposure to a stressor (mild electrical shocks to foot, five times per episode, at 1800, 1830, 1900 and 1930 hrs of proestrus) coinciding with period of pre-ovulatory progesterone secretion in rats abolished estrous behavior as shown by the absence of lordosis response and a significant increase in rejection quotient compared to controls. These rats did not show spermatozoa in the vaginal smear next day morning in contrast to their presence in controls. On the other hand, rats treated with progesterone (a single injection, 500 μg in 0.1 ml olive oil at 1800 hr of proestrus) prior to exposure to stressor showed normal estrous behavior, as shown by significantly lower rejection quotient than rats exposed to stress alone, lordosis quotient similar to controls and presence of spermatozoa in the vaginal smear next day. The results, albeit indirectly, to the best of our knowledge, first time indicate that stress induced impaired steroidogenesis leads to suppression of estrous behavior.
