| Among males, presence of convoluted epididymides and spermatozoa in seminiferous tubules and epididymides were used to define minimum size at sexual maturity. |
| The ductus deferens begins at the tail of the epididymis, in the lower region of the scrotal sac, the pouch of thin skin that covers the testes and epididymides. |
| No treatment-related gross changes in the thoracic or abdominal cavities, testicular weights, or gross or microscopic changes in the testes or epididymides were observed. |
| In rats, there were decreased prostate weights and the presence of immature spermatocytes in the epididymides. |
| There are two ductus deferentes, identical in structure and function, which emerge from the two epididymides. |
| A small volume is from the bulbourethral glands, epididymides and prostate and the major volume contribution is from the seminal vesicles. |
