homeostasis/metabolism
N
• mice exhibit normal gonadotropin-releasing hormone responsiveness
• female mice, but not male mice, exhibit a reduction in serum phospholipids compared with wild-type mice
• male and female mice exhibit decreased serum globulin levels compared with wild-type mice
• male and female mice exhibit an increase in the ratio of albumin to globulin compared with wild-type mice
• in female mice, but not male mice
• in male mice, but not female mice
• basal and Kp-10-stimulated luteinizing hormone levels are reduced in male mice compared to in wild-type mice
• male mice treated with NMDA, RF9 or GALP exhibit less of an increase in luteinizing hormone levels compared with wild-type mice
• following orchiectomy and testosterone treatment, male mice fail to exhibit an increase in luteinizing hormone levels in response to NMDA or RF9 unlike wild-type mice
• male mice treated with senktide fail to exhibit an increase in luteinizing hormone unlike wild-type mice
• following orchiectomy and/or testosterone treatment and withdrawal, mice fail to exhibit a change in luteinizing hormone unlike wild-type mice
• however, mice exhibit normal response to gonadotropin-releasing hormone administration and nor-BNI treatment
• in female mice, but not male mice
• in male mice, but not female mice
• in male mice, but not female mice
