Male reproductive Chapter 6

study of males

the paranchymal organs that produce the sex cells in both sexes

male sex cells

male gonads

testes/testicles produce gametes called

sac the testes are suspended in

the stage of life in which males and females become functionally capable of sexual reproduction

sex hormone responsible for the growth and development of male sex characteristics

a series of tightly coiled tiny tubes in each testis where spermatozoa are formed

the formation of sperm

the serous membrane that surrounds the front and sides of the testicle

where sperm is stored

seminal fluid ejected from the urethra

an enclosed sheath that includes the vas deferens, along with arteries, veins, and nerves

fluid from a series of glands that provide fluid either to nourish or to aid in mobility and lubrication

begins where the seminal vesicles join the vas deferens, and this "tube" joins the urethra

the enlarged tip of the penis

fold of skin surrounding the glans penis at birth

removal of the prepuce

sexual intercourse

condition of being born without a testicle

congenital defect resulting in a downward (ventral) curvature of the penis due to a fibrous band (cord) of tissue along the corpus spongiosum

condition in which the testicles fail to descend into the scrotum before birth

urethral opening on the dorsum (top) of the penis rather than on the tip

urethral opening on the ventral surface (underside) of the penis instead of on the tip

condition of no living sperm in the semen

inflammation of the glans penis

inflammation of the glans penis and foreskin

abnormal enlargement of the prostate gland surrounding the urethra, leading to difficulty with urination

blood test used to diagnose BPH. very high levels may indicate prostate cancer

inflammation of the epididymis, usually a result of an ascending infection through the genitourinary tract

inability to achieve or sustain a penile erection for sexual intercourse

accumulation of fluid in the tunica vaginalis testis

a hardening of the corpus cavernosa of the penis that can cause painful erections

condition of temporary or permanent deficiency of sperm in the seminal fluid; related to azoospermia

inflammation of the testicles

condition of tightening of the prepuce around the glans penis so that the foreskin cannot be retracted

an abnormally prolonged erection

inflammation of the prostate gland

a swelling of the epididymis that contains sperm

twisting of a testicle on its spermatic cord, usually caused by trauma. may lead to ischemia of the testicle

inflammation of a seminal vesicle, usually associated with prostatitis

other term for STD

disease caused by the gram-negative diplococcus Neisseria gonorrhoeae bacterium (Gc), which manifest itself as inflammation of the urethra, prostate, rectum, or pharynx. the cervix and fallopian tubes may also be involved in females, although they may appear asymptomatic

form of the herpesvirus transmitted through sexual contact, causing recurring painful vesicular eruptions

virus that causes common warts of the hands and feet and lesions of the mucous membranes of the oral, anal, and genital cavities.

genital wart

inflammation of the urethra caused by Chlamydia trachomatis, Mycoplasma genitalium, or Ureaplasm urealyticum

multistage STD caused by the spirochete Treponema pallidum. a highly infectious chancre, a painless, red ulcer, appears in the first stage

used to diagnose syphillis

these testicular tumors arise from the stromal tissue of the testes that produce hormones. usually benign

prostate cancer is diagnosed in one of every sex men. with early detection, however, this cancer is treatable

a type of germ cell tumor (GCT). it accounts for the majority of testicular cancer causes and occurs in younger men, usually between 15-35.

this malignancy is one type of GCT that develops from the cells that form the sperm

this tumor is a type of nonseminoma that is usually benign in children. because these tumors are created from germ cells, they have half the necessary genetic information to form an individual

surgically correcting a defect of the glans penis

surgical procedure in which the prepuce of the penis is excised

incision of the epididymis to drain a cyst

imaging of the epididymis and seminal vesicle using a contrast medium

cutting out part or all of one or both testicles, usually for removal of a tumor or cyst

surgical procedure to mobilize an undescended testicle, attaching it to the scrotum

surgically correcting a defect of the penis

removal of the prostate gland.

prostate gland, seminal vesicles and area of vas ampullae of the vas deferens are removed

cutting out the prostate in sections through a urethral approach. the most common type of prostatectomy

form of prostate surgery involving tiny incisions of the prostate. the prostate is not removed

anastomosis of the ends of the vas deferens as a means of reconnecting them to reverse the sterilization techinique

incision, ligation, and cauterization of both the vas deferens for the purpose of male sterilization

imaging of the vas deferens to visualize possible blockages

a tying of the vas deferens as a sterilization procedure

cutting out the seminal vesicle
