2. Male Reproductive System
• Central Node: Male Reproductive System
• Two Main Branches:
• 1. Primary Sex Organs
• 2. Secondary Sex Organs

3. Primary Sex Organs - Testes
• - Seminiferous Tubules: Site of sperm
production
• - Leydig Cells: Produce testosterone
• - Spermatogenesis: Process of sperm
formation

4. Secondary Sex Organs - Overview
• Three Sub-categories:
• 1. Accessory Glands
• 2. Duct System
• 3. External Genitalia

5. Secondary Sex Organs - Accessory
Glands
• - Seminal Vesicles: Produce fructose-rich fluid
• - Prostate Gland: Secretes slightly alkaline fluid
• - Bulbourethral Glands: Lubricates and
neutralizes urethra

6. Secondary Sex Organs - Duct
System
• - Epididymis: Sperm maturation and storage
• - Vas Deferens: Transports sperm
• - Ejaculatory Duct: Pathway to urethra
• - Urethra: Passage for urine and semen

7. Secondary Sex Organs - External
Genitalia
• - Penis: Copulatory organ
• - Scrotum: Holds testes and regulates
