Uterine secretion during the sexual cycle in the rat and its capacity to disperse corona cells in vitro.
It was found that closure of the uterus disturbed the first 2 cycles after the operation; thereafter the normal cycle was resumed. The quantity of uterine fluid was increased at pro-oestrus and oestrus and reduced at met-oestrus and di-oestrus. Slight inverse changes in viscosity were observed. There was no significant difference in the pH. The corona-cell dispersing factor seems to be an oestrogen-dependent constituent of uterine secretion.
