There are three accessory glands of the male genital system: the seminal vesicles, the prostate, and the bulbourethral glands. The seminal vesicles are paired structures on the posterolateral aspect of the base of the bladder, which secrete fluid that will form part of the semen. Aberrations of the proper development of the seminal vesicles can be seen during fetal life, and can occur in association with other genitourinary tract anomalies, owing to the close embryological origin of these complex tissues. Therefore, knowledge of the normal development and histological appearance of the seminal vesicle during fetal life can be useful. This chapter reviews the embryology of the seminal vesicles and highlights the histological features of the fetal seminal vesicles at various points in gestation.
