Increased testicular weight in ghrelin KO mice.
A) Testicular weights and picture of WT, GHSR KO and Ghrelin KO testes. The right testis weight was significantly increased in ghrelin KO mice compared to the WT and GHSR KO mice (80 day old). No significant differences were detected in testis weight between WT mice and GHSR KO mice. Photomicrographs of testis cross-sections from 80 day old WT mice (B), ghrelin KO mice (C) and GHSR KO mice (D). Scale bar = 200 μm. Data were analyzed by one-way ANOVA multiple comparisons Bonferroni's test and expressed as mean ± SEM (** p<0.01).
