What is the male external reproductive organ that delivers sperm to the female reproductive tract?

• A. Penis
• B. Testes
• C. Urethra
• D. Scrotum

Answer: (A)

Delivering sperm to the female reproductive tract requires an external organ that can deposit semen during intercourse. The penis is the external male reproductive organ designed for this function. Inside it runs the penile urethra, the channel through which semen travels during ejaculation to exit at the tip. Sperm are produced in the testes and travel through the vas deferens, mixing with fluids from the seminal vesicles and prostate to form semen, which then passes through the urethra and out. The erection enables penetration and proper delivery into the female tract. The other structures don’t fit this role: the testes produce sperm but don’t deposit it; the urethra is a tube inside the penis, not the external organ itself; and the scrotum mainly supports and temperature-regulates the testes.
