Step 1: Recall what Tyson’s glands are.
Tyson’s glands are sebaceous glands present in the male reproductive system.
They secrete a lubricating substance (smegma).
Step 2: Identify their anatomical location.
These glands are located on the inner surface of the prepuce (foreskin) of the penis, near the glans.
Step 3: Eliminate incorrect options.
Urethra: Passage for urine and semen, not the site of Tyson’s glands.
Scrotum: Sac enclosing testes; contains sweat and sebaceous glands, but not Tyson’s glands.
Epididymis: Coiled tube for sperm maturation, unrelated to glandular secretion.
Hence, the correct answer is
\[
\boxed{\text{prepuce}}
\]
