Figure 3.

Mean pulse parameters of LET, control (CON), and OVX mice from 2.5 hours of in vivo serial LH sampling. Luteinizing hormone pulse frequency (pulses per hour) (A), inter-pulse interval (IPI; the number of minutes between pulses) (B), pulse amplitude (C), pulse peak (zenith value of a pulse) (D), basal LH level (E), and mean LH across the entire sampling period (F) were all significantly different in LET versus CON females. Different letters above bars indicate significantly different (P < 0.05) from each other.
