Flashcards in Male Reproductive System Deck (92)
Testis, or testicle (pl. testes, or testicles)
primary male sex organs, paired, oval-shaped, and enclosed in a sac called the scrotum. The testes produce spermatozoa (sperm cells) and the hormone testosterone.
sperm (spermatozoon, pl. spermatozoa)
The microscopic male germ cell, which when unite with the ovum, produces a zygote (fertilized egg) that with subsequent development becomes an embryo.
the principal male sex hormone. Its chief function is to stimulate the development of the male reproductive organs and secondary sex characteristics such as facial hair.
approximately 900 coiled tubes within the testes in which spermatogenesis occurs
coiled duct atop each of the testes that provides for storage, transit, and maturation of spermatozoa; continuous with the vas deferens
vas deferens, ductus deferens, or seminal duct
duct carrying the sperm from the epididymis to the urethra. The spermatic cord encloses each vas deferens with nerves, lymphatics, arteries, and veins. The urethra also conects with the urinary bladder and carries urine outstide the body. A circular muscle constricts during intercourse to prevent urination.
Two main glands located at the base of the bladder that open into the vas deferens. The glands secrete a thick fluid, which forms part of the semen.
encricles the upper end of the urethra. The prostate gland secretes a fluid that aids in ejaculation.
Sac suspended on both sides of and just behind the penis. The testes are enclosed in the scrotum.
male organ of urination and copulation (sexual intercourse)
enlarged tip on the end of the penis
fold of skin covering the glans penis in uncircumcised males (foreskin of the penis)
composed of sperm, seminal fluids, and other secretions
reproductive organs (male or female)
orchid/o, orchi/o, orch/o, test/o
spermatozoon (pl. spermatozoa), sperm
state of absence of testis (unilateral or bilateral)
inflammation of the glans penis
discharge from the glans penis
benign prostatic hyperplasia (BPH) (be-NIN pro-TAT-ik hi-per-PLA-zha)
excessive development pertaining to the prostate gland (nonmalignant englargement of the prostate gland)
state of hidden testes.
inflammation of an epididymis
