[Estradiol receptors in the hypothalamus of androgenized female and castrated male rats].

The content of receptors to estradiol was determined in cytosol of preoptical-anterior hypothalamic area and arcuate nucleus and medial eminence region of the neonatally androgenized females, neonatally castrate male and, for the control, in sexually mature intact rat males and females. The neonatal androgenization of females resulted in the decrease of the content of receptors in preoptical-anterior hypothalamic area and did no affect their content in arcuate nucleus and medial eminence region. The neonatal castration of males resulted in the increase of the content of receptors in preoptical-anterior hypothalamic area and its decrease in arcuate nucleus and medial eminence region.
