title: Evocability of a slight positive oestrogen feedback action on LH secretion in castrated and oestrogen-primed men.
abstract: Orchidectomized heterosexual men suffering from prostatic cancer with suppressed serum LH values by oestrogen priming exhibited a slight, but significant surge of LH secretion following oestrogen injection. In contrast, orchidectomized and oestrogen-primed heterosexual men with unsuppressed serum LH levels as well as intact heterosexual men did not display any positive oestrogen feedback action on LH secretion,  as it was observed in intact homosexual men.
