Where are testes located?

• A. Suspended in scrotum by the spermatic cord; left = more inferior
• B. In the abdominal cavity
• C. In the inguinal canal
• D. In the penis

Answer: (A)

Testes reside in the scrotum, outside the body cavity, because the cooler environment of the scrotum supports normal sperm production. Each testis is suspended within the scrotum by the spermatic cord, which carries the vas deferens, testicular vessels, nerves, lymphatics, and the cremaster muscle. During development, they descend from the abdomen into the scrotum via the inguinal canal, guided by the gubernaculum. In most people, the left testis hangs a bit lower than the right, a common natural asymmetry of the scrotal contents.
