we conclude that a short-term pituitary refractoriness to lh-rh is present after administration of single pulses of lh-rh in women with amenorrhea of suprapituitary origin and pulses of lh-rh in the physiologic range ( 2 micrograms ) given to these women do not always generate lh and fsh increments that are identifiable as significant hormone pulses .
