Intranasal Insulin Administration Does Not Affect LH Concentrations in Men with Diabetes

Table 2

LH concentrations before and after intranasal insulin or saline administration in healthy lean men.

Lean	Insulin			Saline			Mean difference (95% confidence interval)
	Baseline (0–120 minutes)	Posttreatment (135–300 minutes)		Mean baseline LH (0–120 minutes)	Mean LH after treatment (135–300 minutes)
Mean LH (IU/l)	3.3 ± 1.4	3.4 ± 1.2	0.76	3.6 ± 0.9	3.8 ± 1.4	0.63	−0.1, [−1.1, 0.9]	0.83
Peak LH (IU/l)	4.6 ± 2.0	5.0 ± 1.4	0.51	5.3 ± 1.8	5.4 ± 1.9	0.92	−0.1, [−1.7, 1.5]	0.89
Number of LH pulses (per hour)	0.4 ± 0.2	0.4 ± 0.4	0.87	0.3 ± 0.3	0.3 ± 0.4	0.99	0.0, [−0.5, 0.5]	0.90
Glucose (mmol/l)	5.2 ± 0.7	4.9 ± 0.4	0.37	5.2 ± 0.5	5.1 ± 0.2	0.41	−0.1, [−1, 0.8]	0.74

The penultimate column shows the mean difference between the two treatments.
