Male Genital Organs (Organa genitalia masculina) Internal Genital Organs External Genital Organs Internal Genital Organs Testis Male reproductive gland Leydig Cells (produce testosterone) Sertoli Cells (Structural support and support spermatogenesis) Prenatal Development: ○ Originate in lumbar region ○ Decend and take the abdominal layers with it to form the scrotal layers External Structures of Testis ○ Upper pole (Extremitas Superior) ○ Lower Pole (Extremitas Inferior) ○ Anterior Border (Margo Anterior) ○ Posterior Border (Margo Posterior) ○ Lateral Surface (facies lateralis) ○ Medial Surface (Facies Medialis) Internal Structures of Testis ○ Tunica Albuginea ○ Vascular Layer (Tunica Vasculosa) ○ Septa of Testis (septula testis) ○ Lobules of testis (lobuli testis) ○ Convoluted seminiferous tubules (tubuli seminiferi contori) ○ Straight Tubules (tubuli seminiferi recti) ○ Rete Testis ○ Efferent Ductules (ductuli efferentes testis) Epididymis Composed of tightly packed tubes Serves as a reservoir of spermatozoa Head of Epididymis (Caput epindidymidis) Body of Epididymis (corpus epididymidis) Tail of Epididymis (cauda epididymidis) Sinus of epididymis (sinus epididymidis) Coverings and External Fixation of Testes and Epididymis Tunica Vaginalis (tunica vaginalis testis) ○ Visceral Layer (Lamina visceralis/epiorchium) ○ Parietal Layer (Lamina parietalis/periorchium) Internal Spermatic Fascia (fascia spermatica interna) Cremaster External Spermatic Fascia (Fascia spermatica externa) Dartos Fascia (tunica dartos) Spermatic Cord (Funiculus Spermaticus) Ductus Deferens Artery to ductus deferens (arteria ductus deferentis) Testicular Artery Lymph vessels Pampiniform plexus (plexus pampiniformis) Testicular plexus (plexus testicularis) Deferential plexus (plexus deferentialis) Ductus Deferens Scrotal Part (pars scrotalis) Funicular Part (pars funicularis) Inguinal Part (pars inguinalis) Pelvic Part (pars pelvica) Ampulla of ductus deferens (ampulla ductus deferentis) Seminal Gland (glandula vesiculosa) Simple tubular gland. Produces ejaculate fluid Excretory duct (ductus excretorius) Fuse with ductus deferens to form ejaculatory duct (ductus ejaculatorius) Prostate (prostata) Base of prostate (basis prostatae) Apex of Prostate (apex prostatae) Posterior Surface (facies posterior) Anterior Surface (facies anterior) Prostatic Urethra (pars prostatica urethrae) Histological Zones ○ Peripheral Zone (Zona peripheralis) ○ Central Zone (zona centralis) ○ Transitional Zone (zona transitionis) ○ Anterior fibromuscular stroma Posterior Surface ○ Prostatic Ductules (ductuli prostatici) ○ Urethral Crest (crista urethralis) ○ Seminal Colliculus (colliculus seminalis) ○ Prostatic Utricle (Fetus) (utriculus prostaticus) ○ Openings of the ejsaculatory ducts Bulbo-urethral glands (glandulae bulbourethrales) Empties into beginning of spongious urethra Male urethra (urethra masculina) Prostatic Urethra Membranous Urethra Spongy Urethra External Genital Organs Penis External Structures ○ Root of Penis (Radix Penis) § Bulb of penis (bulbus penis) § Crura of penis (crura penis) ○ Body of penis (corpus penis) § Corpora Cavernosa Penis § Corpus Spongiosum penis § Dorsum of penis (facies dorsalis penis) § Urethral Surface (facues urethralis) § Fundiform ligament of penis (ligamentum fundiforme penis) § Suspensory ligament of penis (ligamentum suspensorium penis) § Raphe of penis ○ Glans penis § Corona of Glans § Neck of Glans (collum glandis) § Foreskin / Prepuce (preputium) § Frenulum § Preputial glands / Tyson's glands (glandulae preputiales) produces smegma Internal Surface of Penis ○ Corpora Cavernosa Penis ○ Corpus Spngiosum Penis ○ Tunica Albuginea ○ Deep fascia of penis / Buck' fascia (fascia penis profunda) ○ Superficial fascia of penis (fascia penis superficialis) Scrotum Tunica Vaginalis Internal Spermatic Fascia Cremaster External Spermatic Fascia Dartos Fascia Skin Sources: Complete Anatomy by 3d4medical Biorender Memorix Anatomy 2nd Edition by Hudák Radovan (Author), Kachlík David (Author), Volný Ondřej (Author) Snell, Richard S.
