Term | Definition |
Bulbourethral Glands | Pair of exocrine glands near male urethra. Secrete fluid into urethra. AKA Cowper Glands |
Ejaculation | Ejection of sperm and fluid from male urethra |
Ejaculatory Duct | Tube through which semen enters male urethra |

Stromal Tissue | Supportive, connective tissue of an organ, distinguished from its parenchyma. AKA stroma |
Testies (plural: testes) | Male gonad (testicle) that produces spermatozoa and the hormone testosterone. |
Testosterone | Hormone secreted by interstitial tissue of testes; responsible for male sex characteristics |
Vas Deferens | Narrow tube (one on each side) carrying sperm from epididymis toward urethra. AKA ductus deferens |
