Which gland secretes fluid that lubricates the urethra during intercourse?

The bulbourethral glands, also known as Cowper's glands, are responsible for secreting a fluid that lubricates the urethra during sexual arousal and intercourse. This fluid, which is typically a clear and viscous secretion, helps to neutralize any acidity in the urethra and provides lubrication, making the passage easier for sperm during ejaculation.

The function of these glands is vital for male reproductive health, as the lubricant they produce can enhance comfort during intercourse and help facilitate the movement of sperm. The bulbourethral glands are located near the base of the penis and their secretion occurs prior to ejaculation, ensuring that the urethra is well-prepared for the passage of sperm and seminal fluid.

While other glands, such as the prostate and seminal vesicles, play crucial roles in producing components of semen, their primary functions differ from that of the bulbourethral glands. The prostate contributes to the fluid component of semen but does not specifically serve the lubrication role for the urethra. Seminal vesicles primarily produce a fructose-rich fluid that nourishes sperm but do not provide urethral lubrication either. The adrenal glands are not involved in the reproductive system in this context. Thus, the bulbourethral
