Ejaculatory duct

Epididymis
One of a pair of long, tightly coiled tubes on top of each testis; Carries sperm from the seminiferous tubules to the vas deferens
Erectile dysfunction

Flagellum
Hair like projection on a sperm cell that makes it motile (able to move)
Fraternal twins
Two infants born of the same pregnancy from two separate egg cells fertilized by two different sperm cells

Seminiferous tubules

Spermatozoon
Sperm cell
Sterilization
Procedure that removes an individual’s ability to produce or release reproductive cells
Stroma
Supportive, connective tissue of an organ
Testis
Male go ad that produces sperm and testosterone
Testosterone
Hormone secreted by the interstitial tissue of the testes; responsible for male sex characteristics
Vas deferens
Narrow tube that carries sperm from the epididymis into the body and toward the urethra
Bulbourethral glands
A pair of exocrine glands near the male urethra; secrete fluid into urethra (Cowper glands)
