seminal vesicles

Two small, elongated, sac-like containers situated on the PROSTATE GLAND at the point at which the VAS DEFERENS passes through to join the URETHRA. The seminal vesicles store part of the SEMINAL FLUID until it is discharged by ejaculation. Their secretion contributes most of the volume of the ejaculate but the vesicles do not store spermatozoa.
