Frequent blood sampling during an 8-hour iv infusion of vehicle or NKB (at an initial rate of 5.12 nmol/kg/h) to healthy men (study 3). Subjects underwent 10 minutes of blood sampling for 8 hours (n = 5/group) during an 8-hour vehicle infusion and then an 8-hour NKB infusion within 2 days. A, Time profile of mean serum LH during vehicle or NKB infusion. B, Mean serum LH for entire vehicle or NKB study. C, Mean number of LH pulses during the entire vehicle or NKB study. D, Mean secretory mass per LH pulse during the entire vehicle or NKB study. Data are shown as mean ± SEM.
