Which gland secretes lubrication of the glans?

Lubrication of the glans is provided by the bulbourethral glands, also known as Cowper's glands. During sexual arousal they release a clear mucus called pre-ejaculate that coats the glans and the urethra. This fluid reduces friction and helps protect sperm by neutralizing residual acidity in the urethra before ejaculation. The glands themselves are small and located near the base of the penis, just below the prostate, and they secrete directly into the urethra. The other structures mentioned are not responsible for lubricating the glans: the vas deferens is a duct that carries sperm from the epididymis toward the urethra; the seminal vesicles produce most of the fluid component of semen, rich in fructose to nourish sperm; the prostate adds additional fluids to semen but does not provide the lubrication of the glans itself.
