Comparison between LH- and hCG-induced cAMP production by dose–response experiment. Murine primary Leydig cells were stimulated by increasing doses of hCG and LH, in the presence of 500 μM IBMX. Total cAMP was measured after 3 h of incubation and cAMP levels were normalized as percentage of the maximal response. All the results are represented as means ± SEM in a logarithmic X-axis, then non-linear regressions were plotted. The EC50 cAMP values were compared (LH EC50 = 192 ± 53.96 pM; hCG EC50 = 18.64 ± 10.14 pM; means ± SEM; Mann-Whitney’s U-test; P = 0.0286; n = 4)
