Mean (±SEM) LH Concentrations (Nanograms per Milliliter) Related to the Surge in Intact Proestrous and OVX+E+E Mice
| . | n . | Basal LH, ng/mL . | Peak Value, ng/mL . | Time of Peak LH Value After Lights Off, h . |
|---|---|---|---|---|
| OVX+E+E surge | 8 | 2.24 ± 0.25 | 7.70 ± 0.69 | 1.06 ± 0.18 |
| Proestous surge | 5 | 1.51 ± 0.41 | 14.50 ± 1.73a | 0.7 ± 0.25 |
| . | n . | Basal LH, ng/mL . | Peak Value, ng/mL . | Time of Peak LH Value After Lights Off, h . |

| OVX+E+E surge | 8 | 2.24 ± 0.25 | 7.70 ± 0.69 | 1.06 ± 0.18 |
| Proestous surge | 5 | 1.51 ± 0.41 | 14.50 ± 1.73a | 0.7 ± 0.25 |
Data are the LH levels prior to the initiation of the surge (basal) and at the peak of the surge (peak). The mean (±SEM) time is given at which the peak LH value occurred after light offs at 6:00 pm.
Peak LH levels were significantly higher in proestrous compared with OVX+E+E mice (P < .01, Mann-Whitney test).
