bulbourethral glands
pair of exocrine glands near male urethra; cowper glands
ejaculation
ejection of sperm and fluid from male urethra
ejaculatory duct
tube through which semen enters the male urethra
epididymis

erectile dysfunction
inability of an adult male to achieve an erection; impotence
flagellum

fraternal twins
two infants resulting from fertilization of two separate ova by two separate sperm cells
glans penis

sperm cell
sterilization
procedure that removes persons ability to reproduce or release repro cells thorugh removal of testicles, vasectomy or oophorectomy
stromal tissue
supportive connective tissue or an organ; stroma

testosterone
sectreted by interstitial tissue if the testes; responsible for the male sex characteristics
