vas deferens, external and internal cremaster muscle)
- Pampiniform plexus
- heat exchange
- testosterone exchange
- pulse pressure eliminator
- Tunica dartos muscle
- Gubernaculum (connective tissue)
Secondary sex organs (leading to exterior)
- Vas efferentia (ductuli efferentes)
- Epididymis - head, body and tail (caput, corpus, cauda)
- Vas deferens (ductus deferens)
- Ampulla of vas deferens
- Urethra (pelvic and penile)
- Penis

The Penis
- Retractor Penis Muscle

- End of Penis - glans penis, raphe, free part of penis, prepuce
Blood supply
- Arteries
- Aorta
- Testicular artery
- External Iliac
- Umbilical
- Internal Iliac
- Prostatic
- Internal Pudendal
- Veins - use similar paths but terminate in Vena Cava
