Penis: The external organ composed of erectile tissue that facilitates sexual intercourse, urination, and ejaculation. It includes the glans penis (tip) and is often covered by the foreskin in uncircumcised males.
Scrotum: A pouch of skin and muscle that encloses the testes, functioning to regulate testicular temperature (around 34-35°C) essential for optimal sperm production.
Testes (Testicles): Paired oval organs located within the scrotum that produce sperm (spermatogenesis) and secrete testosterone, the primary male sex hormone.
Foreskin (Prepuce): A fold of skin covering the glans penis in uncircumcised males, which can be surgically removed via circumcision.
Erectile Tissue: Spongy tissue within the penis that fills with blood during an erection, enabling penetration during sexual activity.
