Minute-to-minute fluctuations of serum LH and FSH concentrations resembling a pulsatile pattern were demonstrated in both pre- and post-menopausal women. A pulsatile pattern of LH but not FSH was seen during the menstrual cycle. These appear to follow a varying frequency and magnitude according to the different phases of the cycle; a periodicity of 1–2 hr was seen during the early follicular phase, early luteal phase and midcycle surge while a periodicity of 4 hr was seen in the mid- and late-luteal phase. During the late follicular phase only “minor oscillations” were noted. A greater net increase of circulating LH was found in pulses during the midcycle surge which was more than double that seen during other phases of the cycle. In contrast, post-menopausal subjects had pulses of both gonadotropins. These were usually coincident, however, a minor asynchrony between LH and FSH patterns was discernible. The frequency of pulses in the postmenopausal subjects was the same as in the follicular phase and midc...
