What are the testes and their role in male anatomy?

📚 Quick Study Guide

• 🔬 The testes, also known as testicles, are the male gonads.
• 🧬 They are responsible for producing sperm and testosterone.
• 🌡️ The testes are located in the scrotum, which helps regulate their temperature for optimal sperm production.
• ⚙️ Sperm production (spermatogenesis) occurs in the seminiferous tubules within the testes.
• hormone production (testosterone) occurs in the Leydig cells.
• 🩸 Blood-testis barrier protects sperm from the immune system.
• 🩺 Testicular health is vital for male fertility and overall well-being.
