Patient's question:
I didn't think I was sick at first, but I often felt abdominal pain and found it uncomfortable when urinating. I experienced frequent urination and urgency. Sometimes, I would only urinate a little but still feel the urge, so I had to strain a bit to urinate again. The most shocking thing was when I saw red semen during masturbation, which made me decide to see a doctor. The examination revealed "seminal vesicle cyst."Doctor's answer:
Hello! Congenital seminal vesicle cysts can be divided into two categories based on their origin: those arising from the seminal vesicle itself and those formed due to abnormal development of the mesonephric duct during the embryonic period. During the development of the male embryo, the paramesonephric duct, mesonephric duct, and some remaining mesonephric tubules either transform into useful structures or degenerate into useless ones. Certain parts often form residual tubular or vesicular structures that persist in the tissues of the testis, epididymis, or seminal vesicle. Some of these structures develop into cysts, while others may form cysts over a long period of postnatal life due to abnormal proliferation caused by certain factors.
