The recent development of antibodies specific for individual gonadal steroid receptors has been of great use in determining precisely which cells in the hypothalamus express androgen, oestrogen and progesterone receptors. In the sheep brain, both oestrogen and androgen receptor antibodies have been used successfully and th...
