Study Notes
Male Reproductive System
- Gonads (Testes): Male reproductive glands responsible for sperm production and testosterone synthesis.
Testes Structure and Function
- Scrotum: External pouch that regulates testicular temperature for optimal sperm production.
- Tunica Albuginea: Fibrous covering surrounding the testis.
- Seminiferous Tubules: Coiled structures within the testes where spermatogenesis (sperm production) occurs.
- Interstitial Cells (Leydig Cells): Cells producing testosterone, the primary male sex hormone.
- Epididymis: Coiled tube where sperm mature and are stored after leaving the seminiferous tubules.
Pathway of Sperm
- Ductus (Vas) Deferens: Tube carrying sperm from the epididymis to the ejaculatory duct.
- Ejaculatory Duct: Fusion of the vas deferens and seminal vesicle duct; passes through the prostate and opens into the urethra.
- Urethra: Common duct for both sperm and urine exiting the body.
Accessory Glands and Fluid
- Seminal Fluid (Semen): Fluid containing sperm and produced by accessory glands.
- Seminal Vesicles: Glands producing a significant portion of seminal fluid, rich in fructose, vital for sperm nourishment.
- Prostate Gland: Produces a nourishing fluid to aid with sperm transport.
- Bulbourethral Glands (Cowper's Glands): Produce a pre-ejaculatory fluid that lubricates the urethra.
External Genitalia
- Scrotum: External pouch containing the testes.
-
Penis: Male copulatory organ.
- Corpus Spongiosum: Erectile tissue surrounding the urethra, preventing collapse during erection.
- Corpora Cavernosa: Two erectile tissues filling with blood for erection.
- Glans: Sensitive tip of the penis.
- Prepuce (Foreskin): Fold of skin covering the glans (often removed in circumcision).
