Abstract
This study reports the quantitative immunohistochemical distribution of luteinizing hormone-releasing hormone (LH-RH) neurons within rostral forebrain of young (5-6 month) and old (26-28 month) C57BL/6J mouse. Old mice demonstrated a significant (18%) loss of LH-RH-containing neurons (p < 0.001, ANOVA). The most striking losses involved the preoptic area (24%) and more rostral regions (26%). The presence of pituitary or mesenteric tumors in order mice did not affect the density of LH-RH neurons. These observations indicate that LH-RH neurons comprise part of the neuronal population previously reported to be reduced in the preoptic area of older mice (4).
