Term | Definition |
Bulbourethral Glands | Pair of exocrine glands near the male urethra. They secrete fluid into the urethra. Also known as Cowper Glands |
Ejaculation | Ejection of sperm and fluid from the male urethra |
Ejaculatory Duct | Tube through which semen enters the male urethra |
Epididymis | One of a pair of long, tiny coiled tubes each testis. It stores and carries sperm from the seminiferous tubules to the vas deferens |
Erectile Dysfunction | Inability of an adult male to achieve an erection; impotence |
Flagellum | Hair-like projection on a sperm cell that makes it motile (able to move) |
Fraternal Twins | Two infants resulting from fertilization of two separate ova by two separate sperm cells |
Glans Penis | Sensitive tip of the penis; comparable to the clitoris in the female |
Identical twins | Two infants resulting from division of one fertilized egg into two distinct embryos. |
Conjoined Twins | Incompletely separated identical twins |
Interstitial cells of the testes | Specialized cells that lie adjacent to the seminiferous tubules in the testes. These cells produce testosterone and are also called Leydig cells |
Parenchymal tissue | Essential distinctive cells of an organ. In the testis, the seminiferous tubules that produce sperm are parenchymal |
Penis | Male external organ for reproduction |
Perineum | External region between the anus and the scrotum in the male |
Prepuce | Foreskin; fold of skin covering the tip of the penis |
Prostate gland | Exocrine gland at the base of the male urinary bladder. The prostate secretes one of fluid parts of semen into the urethra during ejaculation |
Scrotum | External sac that contains the testes |
Semen | Spermatozoa (sperm cells) and seminal fluid (prostatic and seminal vesicle secretions) discharged from the urethra during ejaculation |
Seminal Vesicles | Paired sac-like exocrine glands that secrete fluid (a major component of semen) into the vas deferens |
Seminiferous tubules | Narrow, coiled tubules that produce sperm in the testes |
Spermatozoon | Sperm cell |
Sterilization | Procedure that removes a person's ability to produce or release reproductive cells; removal of testicles, vasectomy, and oophorectomy are sterilization procedures |
Stromal Tissue | Supportive, connective tissue of an organ, as distinguished from it's parenchyma. Also called Stroma |
Testis | Male Gonad- Testicle that produces sperm and the hormone testosterone. Remember! Testis is on testicle, Testes are two testicles |
Testosterone | Hormone secreted by interstitial tissue of the testes. Responsible for male sex characteristics |
Vas Deferens | Narrow tube (one on each side) carrying sperm from the epididymis toward the urethra. Also called the ductus deferens |
