Male genitalia - Rce - Chn

Penis

— The male external sex organ used for urination and sexual activity

Shaft of penis

— The long part of the penis

Glans

— Corona

— The round tip or “head” of the penis

Prepuce

— The foreskin that covers the glans(if not circumcised)

Urethra

— The tube inside the penis where urine and semen come out

Frenulum

— A small, sensitive band of tissue under the glands that connects to the shaft

Scrotum

— Loose sac of skin behind the penis that hold and protects the testicles

Rugae

— Wrinkled skin of the scrotum

— Helps with the temperature

— Contracts when cold

— Relaxes when warm

Testes

— Make sperm and male hormone(testosterone)

Tunica vaginalis

— Thin cover that protects the testes

Spermatic cord

— Holds the vas deferens, blood vessels, and nerves

Vas deferens

— Tube that carries sperm; longer on the left side

Epididymis

— Stores and matures sperm

Prostate gland

— Produces fluid that helps sperm move and survive

Cowper’s glands

— Produce a clear fluid that lubricates the urethra before ejaculation

Seminal Vesicles

— Produces fa sugary fluid that mixes with sperm to make sperm

Chancre

— Signals primary syphilis

— Painless, ulcerated, exudative

— Papular lesion with an erythematous halo surrounding edema a friable base

Chancroid

— Caused by haemophilus through small breaks in epidermal tissue

— Pinhead papules to cauliflower-like groupings of painful lesions

Condyloma acuminatum

— Genital warts

— Caused by HPV infection

— Multifocal, wartlike, maculopapular lesions

— Tan, brown, pink, violet, or white

Candida

— Superficial mycotic infection of moist cutaneous sites

— Erythematous plagues with scaling, papular lesions with sharp

Hereptic lesions

— Herpes simplex virus 1 and 2

— Painful eruptions of pustules and vesicles that rupture

— Fever, headache, dysuria, DYSPAREUNIA (painful intercourse), and urinary retention may occur

Dysuria

— Painful urination

Dyspareunia

— Painful intercourse

Tinea cruris

— Fungal infection of the groin often referred to as jock itch

Priapism

— Penis stays hard(erect) for more than 4 hours, even without sexual arousal

— Often associated with leukemia, metastatic carcinoma, or sickling hemoglobinopathies

Chordee

— Ventral or dorsal curvature of penis

— seen mostly with epispadias (pee hole is in the wrong place)

Phimosis

— Occurs in uncircumcised males

— Foreskin is unable to retract and may become swollen

Spermatocele

— Nontender, well-defined

— Cystic mass on superior testis or epididymis caused by blockage of efferent and ductules of rete testis

Varicocele

— Varicose veins of spermatic cord that feel like a “bag of worms” and slowly collapse when scrotum is elevated

— caused by dilated veins in pampiniform plexus of spermatic cord

— Right-sided may indicate obstruction at vena cava

Sebaceous cyst

— Round, firm, nontender

— Cutaneous cyst confined to scrotal skin

— Decrease in localized circulation

— Closure of sebaceous glands or ducts

Epispadias

— Urethral meatus opens on dorsal (upper) side of penis

— A congenital defect

— Exstrophy is the treatment

Hypospadias

— Urethral meatus opens on ventral(under) side of the penis

— A congenital defect

Testicular torsion

— Testicle that is enlarged, retracted, in a lateral position, and extremely sensitive

Cryptorchidism

— Related to testicular failure, deficient gonadotrophic stimulation, mechanical obstruction, or gubernacular defects.

Orchitis

— Is acute, painful swelling of testicle and worm scrotal skin. Patient may feel heaviness in scrotum

Red glow on transillumination

— Serous fluid within scrotal sac

— Occurs in hydrocele and spermatocele
