Synonyms
Seminal glands; Vesicular glands
Anatomy
Seminal vesicles are a pair of glands located below the bladder, lateral to the vas deferens, and in connection with the base of the prostate (Tjionas et al. 2015).
Function
Seminal vesicles release up to 60% of the fluid found in semen. The other 40% is produced by the prostate and bulbourethral glands.
Size
The normal seminal vesicle measures 3.0 cm ± 0.8 in length and 1.5 cm ± 0.4 in diameter.
Macroscopy
Seminal vesicles are a pair of glands located below the bladder and in connection with the base of the prostate. The vesicles are blind pouches and are rounded on their most superior aspects and taper to their inferior aspects (Fig. 1).
