FUNCTIONS OF SEMINAL FLUIDS

During ejaculation, the penis expels a fluid called semen made of sperm and fluids from the following three glands:

1. SEMINAL VESICLE: Secretes a high energy (fructose) fluid that serves as an energy source for sperm (motility)

2. PROSTATE: Secretes a milky, basic solution that neutralizes the acidic vagina and urethra); enhances sperm motility (sperm=more efficient and effective as a result)

3. COWPER'S: Secretes a mucus-like fluid that lubricates sperm and semen for intercourse
