Healthy, adult, male and female goat temporomandibular retrodiscal tissues were characterized to determine if biochemical differences existed between the genders. RNA concentrations were not different between male and female retrodiscal tissues; however, the DNA concentration in female retrodiscal tissues was 82% greater than in male retrodiscal tissues. Collagen concentrations were significantly greater in male retrodiscal tissues, and this was reflected in significant gender differences of type I and III collagen concentrations. More specifically, male temporomandibular retrodiscal tissues contained 70% more type I collagen and 119% more type III collagen when compared to female retrodiscal tissues. These differences in collagens and DNA reflect a gender difference in temporomandibular retrodiscal tissue composition that underlies divergent biomechanical and neurophysiological properties.
