Plasma concentration of LH, FSH, prolactin, progesterone and estradiol-17beta throughout the 4-day estrous cycle of the rat.

Endocrinology, 1974
Groups of female rats were decapitated at 3-hr intervals throughout 4-day estrous cycles and the plasma of each rat was assayed for LH, FSH, prolactin, progesterone and estradiol-17β.

THE TEMPORAL RELATIONSHIP BETWEEN GONADOTROPIN RELEASING HORMONE (GnRH) AND LUTEINIZING HORMONE (LH) SECRETION IN OVARIECTOMIZED EWES1

, 1982
Hypothalamo-hypophyseal portal blood has been collected from conscious OVX ewes by a procedure that permits maintenance of pituitary function. GnRH was measured in portal plasma and LH was measured in peripheral (jugular) plasma.

Low energy availability, not stress of exercise, alters LH pulsatility in exercising women.

Journal of applied physiology, 1998
We tested two hypotheses about the disruption of luteinizing hormone (LH) pulsatility in exercising women by assaying LH in blood samples drawn at 10-min intervals over 24 h from nine young, habitually sedentary, regularly menstruating women on days 8, 9,

The menopausal transition: analysis of LH, FSH, estradiol, and progesterone concentrations during menstrual cycles of older women.

Journal of Clinical Endocrinology and Metabolism, 1976
Studies of menstrual cycle length in large populations demonstrated that there is a striking increase in the variability of intermenstrual intervals just before menopause.

Time course of serum estrogen and luteinizing hormone (LH) concentrations during the menstrual cycle of the rhesus monkey.

Endocrinology, 1971
Estradiol and LH levels were measured by radioimmunoassay in daily samples of peripheral serum of rhesus monkeys during 10 normal menstrual cycles. During the 4 days prior to the LH surge, serum estradiol values rose sharply, while the LH levels declined.

Role of estrogen as initiator of daily LH surges in the ovariectomized rat.

Endocrinology, 1975
The following studies were performed to determine whether the occurrence of daily LH surges in long-term ovariectomized rats requires an increment in circulating estradiol concentrations, and if so, to investigate the nature of the estrogen stimulus.
