Study Notes
Male Reproductive System Overview
-
Testes: Site of sperm production
-
Seminiferous tubules: Where spermatogenesis occurs
- Sertoli cells: Support and nourish developing sperm cells
- Spermatogenic cells: Cells undergoing sperm development
- Leydig cells: Produce testosterone
-
Testicular duct system: A network of tubules that transport sperm
- Tubulus rectus: Connects seminiferous tubules to rete testis
- Rete testis: Network of channels within the testes
-
Seminiferous tubules: Where spermatogenesis occurs
-
Extra-testicular duct system: Connects testes to the urethra
- Epididymis: Where sperm mature and are stored
- Ductus deferens: Carries sperm from epididymis to urethra
- Efferent ductules: Connect rete testis to epididymis
-
Accessory Glands: Contribute fluids to semen
- Seminal vesicles: Produce a fluid rich in fructose and prostaglandins
- Prostate gland: Produces an alkaline fluid that helps neutralize the acidic environment of the vagina
Spermatogenesis
- Process of sperm production within seminiferous tubules
-
Stages of Spermatogenesis:
- Spermatogonia: Undifferentiated germ cells
- Primary spermatocytes: Diploid cells that undergo meiosis I
- Secondary spermatocytes: Haploid cells produced after meiosis I
- Spermatids: Haploid cells produced after meiosis II
- Spermatozoa: Mature sperm cells
Structures of the Male Reproductive System
-
Testis: Paired oval organs responsible for sperm production
- Tunica albuginea: Fibrous capsule surrounding the testes
- Mediastinum testis: Connective tissue separating the testis into lobules
- Efferent ductules: Small ducts that connect rete testis to epididymis
- Epididymis: A coiled tube where sperm matures and are stored
- Vas Deferens (Ductus deferens): Thick-walled muscular tube transporting sperm from the epididymis
- Seminal Vesicle: Paired glands that produce a fluid rich in fructose and prostaglandins
- Prostate: Gland surrounding the urethra that produces a milky, alkaline fluid
