What do bulbourethral glands secrete?

• A. Alkaline fluid that counteracts acid in male urethra and female vagina.
• B. Slightly acidic, watery secretion
• C. Mucus
• D. Proteolytic enzymes

Answer: (A)

Bulbourethral glands produce an alkaline, clear mucus-like fluid that lubricates the penile urethra and helps neutralize acidic environments, including residual acidity in the urethra and, when present, the vaginal environment. This alkaline secretion raises pH so sperm can survive and move more easily as ejaculation begins. It is released as pre-ejaculate, not as a simple acidic secretion, a watery fluid, or proteolytic enzymes.
