Overview
Accessory male genital organs store transport and contribute seminal fluid to support sperm viability and fertilization. The epididymis matures sperm the vas deferens transports them and seminal vesicles and prostate add seminal components. Pathology affects fertility and urinary function.
Epididymis and Vas Deferens
The epididymis stores and matures sperm while the vas deferens conveys sperm during ejaculation. Obstruction infection and congenital anomalies impair fertility. Ultrasound evaluates scrotal and ductal pathology.
Seminal Vesicles and Prostate
Seminal vesicles produce fructose rich fluid and the prostate contributes enzymes and alkaline fluid to semen. Prostatic enlargement infection and malignancy affect urinary and reproductive function. Imaging and biopsy guide diagnosis and treatment.
Clinical Relevance
Accessory organ disorders include epididymitis obstructive azoospermia prostatitis and seminal vesicle cysts. Fertility evaluation and urologic management address structural and infectious causes. Assisted reproductive techniques bypass some obstructive issues.
