Effects of oxytocin and estradiol on volumes of the cell nuclei of the pituitary pars intermedia in male rat.
After administration of estradiol, oxytocin and both together to a male rat, investigations of the pituitary pars intermedia were performed. Diminution of the cell nuclei volumes after simultaneous administration of oxytocin and estradiol was observed. The experiment has stressed the role of both hormones in melanotropin release control.
