內部性器官：生殖管道系統 |
位置、形狀與功能
睾丸產生的精子由生殖管道運送直至從身體釋放出去。這些成對的生殖管道（依次是：附睾、輸精管和射精管）從睾丸引出，進入腹腔，最後與尿道匯合。尿道是一條既排出精子也導出尿液的單一管道。 |

The
Internal Sex Organs: The System of
Genital Ducts |
Location, form and function
The sperm cells produced in the testicles are transported to their point of discharge from the body by a system of genital ducts. These ducts, which consist of matched pairs (in sequence: epididymides, vasa deferentia, ejaculatory ducts), lead from the testicles into the abdominal cavity where they eventually join the urethra, a single tube which discharges sperm as well as urine. |
