sac-like pouches attached to vas deferens near base of bladder
produce and secrete fructose-rich seminal fluid
What substances does the fluid produced by seminal vesicles contain?
- amino acids,
What are the functions of the fluid produced by the seminal vesicles?
- provide nutrients and energy for sperm
- help with sperms' motility (ability to move)
- neutralize acidic environment of vagina
The secretions of the seminal vesicles make up ____________ percent of total semen volume.

located on sides of the urethra just below prostate gland
secretes viscous alkaline fluid before ejaculation
. This fluid serves to lubricate the urethra and to neutralize any acidity that may be present due to residual drops of urine in the urethra.
What is the purpose of the fluid secreted by the bulbourethral gland?
- neutralize acidity that may be present due to residual drops of urine in urethra (because urethra is also the duct through which urine travels during urination.)
- helps lubricate urethra
