Abstract: Semen samples from an 18-month-old infertile Lamancha buck contained less than 10% motile spermatozoa and a high incidence of morphological abnormalities. Degenerate detached heads, tightly coiled tails, and thickened midpieces were the prominent morphological defects, affecting 46%, 30%, and 15% of ejaculated spermatozoa, respectively. At necropsy, the diagnosis of testicular degeneration was made, characterized by focal, noninflammatory seminiferous tubule occlusion and mineralization, with a more generalized sloughing of tubular germinal epithelium. When examining spermatozoa morphology from various sites of the excurrent ducts, detached heads were readily seen in efferent duct fluid (> 30% incidence) and the coiled tails and other midpiece defects became prominent with passage through the caput epididymis. |
