The bulbourethral glands, also known as Cowper’s glands, secrete a clear, lubricating fluid. This secretion occurs during sexual arousal and plays a crucial role in the male reproductive system.
The primary function of this fluid is to neutralize any acidity in the urethra, which can enhance the viability of sperm. Additionally, it helps to lubricate the urethra, making the passage smoother for sperm during ejaculation. This clear fluid may also contain small amounts of sperm, though typically not enough to result in conception.
