Estrous cycle alteration.

<p>Estrous cycle determined according to the observation of the cell population of vaginal washes was daily followed on mice in standard conditions (CT), or separated and submitted to food access restriction (SBA) from day 0 to day 70, followed by 20 days of standard housing conditions. D = diestrus, M = metestrus, E = estrus, P = proestrus, 0 = no cell observed. <i>A</i>: A representative example of estrous cycle of CT mice. <i>B</i>: A representative example of cycles observed in SBA mice, with the onset of long duration diestrus during the recovery period. <i>C</i>: A representative example of cycles observed in SBA mice, with the onset of estrus during the recovery period.
