Study Notes
Male Reproductive Organs
- The male reproductive organs are located in the pelvic region.
- The tunica albuginea, a fibrous layer, surrounds each testis and provides protection and support.
Sperm Production
- Sperm production occurs in the seminiferous tubules within the testes.
Hormone Production
- The interstitial cells, also known as Leydig cells, are responsible for producing male sex hormones (androgens) in the testes.
Accessory Glands
- The bulbourethral glands produce a mucous secretion that helps to neutralize acidity in the urethra and facilitate sperm movement.
- The seminal vesicles produce a protein-rich secretion that makes up a significant portion of semen, providing nutrients and energy for sperm.
Sperm Maturation
- Sperm cells become fertile and capable of fertilizing ova in the epididymis.
Sperm Storage
- Mature sperm are stored in the epididymis.
Ejaculatory Ducts
- Each ejaculatory duct passes through the prostate gland before emptying into the urethra.
Urethra
- The urethra serves as the passageway for reproductive fluids.
Prostate Gland
- Benign prostate hypertrophy occurs in the prostate gland.
- The prostate gland is divided into lobes, including the median lobe.
Sertoli's Cells
- Sertoli's cells, located in the seminiferous tubules, provide support and nourishment to developing sperm cells.
Spermatic Cord
- The spermatic cord forms a cord-like structure along with nerves and blood vessels.
Ejaculatory Ducts Location
- The two ejaculatory ducts are located on either side of the median lobe of the prostate gland.
