A 4-year-old alpaca stud was presented for examination of his reproductive tract. Ultrasonographic examination of the gonads revealed 2 cystic structures associated with the head of each epididymis. Biopsies of each testicle evidenced mild testicular degeneration. Histopathologic examination of the gonads revealed cystic efferent ductules in the head of each epididymis.
