Study of the hypothalamic-pituitary-ovarian axis, dysfunctional uterine bleeding.

Descripción del Articulo

We have studied the interplay of hypothalamus-pituitary and ovarian cancer for three months in three cases of young women with dysfunctional uterine bleeding, by radioimmunoassays serial plasma determinations of FSH, LH, estradiol and progesterone. In 2 patients novulatorios cycles were observed eve...
