1. Seminal vesicles
• Alkaline fluid – neutralizes the acidity of the male urethra and vagina
in order to facilitate the survival of spermatozoa.
• Fructose – provides an energy source for spermatozoa.
• Prostaglandins – have a role in suppressing the female immune
response to foreign semen.
• Clotting factors – designed to keep semen in the female reproductive
tract post-ejaculation.
