Male reproductive system

Explore the intricate network of the male reproductive system, including the testes, epididymis, prostate gland, seminal vesicles, and penis. Delve into the functions of glands, ducts, and accessory organs, learning about spermatogenesis and the vital role of each structural unit. Gain insights into the composition and barriers within the testis and the process of sperm maturation and storage in the epididymis and ductus deferens. Understand the prostate gland and seminal vesicles' roles in ejaculation and the unique urethral zones of the penis.
