• Vas Deferens 
• Urethra

Gilt: Has a smaller reproductive tract and the ovaries have less structures present on them

• Passageway for urine 
• Receptor for penis during copulation 
• Passageway for fetus during birth
• Protection - prevents material from environment from entering tract

• Receive sperm from testis
• Transports sperm to urethra

• 1. Head: Receive sperm from testes; Concentrates sperm
• 2. Body: Sperm maturation 
• 3. Tail: Sperm storage

• Produce male gamete
• Produces testosterone

• 1. Pampiniform Plexus
• 2. Cremaster Muscle
• 3. Vas Deferens

• Provide attachment and support of the testis to the body
• Provide vascular, nervous, and lymphatic connection to body
• Heat exchange
• Pulse pressure eliminator

• Heat exchange
• Hormone Exchange

• Aid in temperature control 
• Primary muscle supporting the testis 
• *Not responsible for long-term raising

• Transport sperm
• Non-excited: Steady smooth contractions
• Excited: Increase contractions (strength and number)

Transport of sperm from vas deferens to the outside environment

• 1. Vesicular Glands (seminal vesicles) 
• 2. Prostate Glands
• 3. Bulbourethral Glands

Add volume to ejaculate

• Secrete fluid to clean and lubricate urethra 
• Add small amount of volume to semen

Produce viscous secretion that will cause seminal plasma to coagulate following ejaculation

Male organ of copulation

Part of Penis that has a S-shaped configuration

• Found in the Sigmoid Flexure
• Relaxed state: Contracted
• Excited State: Extended, relaxed

Common area for reproductive and urinary system
