What does the prostate do?
Secretes a slightly alkaline fluid which increases sperm motility and aids in fertilization by neutralizing acidic secretions of the vas deferens and vagina.
Prostatic secretions include:
- Zinc
- Citric acid
- Prostaglandins
- Acid phosphatase
- Prostate specific antigen (PSA)
- Other proteases involved in the liquifaction of semen.
