Seminal vesicle enlargement is usually seen in seminal vesiculitis. Seminal vesicle, also known as seminal vesicle gland, is a pair of accessory glands of male genitalia. They produce seminal vesicle fluid, which provides carrier and nutrients for sperm, and is conducive to the transport and storage of sperm. Seminal vesiculitis is caused by bacteria invasion. Bacteria invasion, such as Escherichia coli infection, or any other factors that lead to prostatitis and hyperemia in seminal vesicle, will cause bacterial infection in seminal vesicle and result in inflammation. Hemospermia (blood in semen) is the main symptom of seminal vesicle inflammation. Seminal vesiculitis can be divided into non-specific seminal vesiculitis and specific seminal vesiculitis, the former includes acute seminal vesiculitis and chronic seminal vesiculitis; the latter includes seminal vesicle tuberculosis and gonococcal seminal vesiculitis. Nonspecific chronic seminal vesiculitis is the most common in clinic. Seminal vesicle is not an organ for semen storage. It is a pair of elongate oval saccular organs located beneath the bottom of the bladder, outside the ampulla of the spermaduct. Seminal vesicle has a wide top and a narrow end, slightly flat in depth, and with a bumpy surface. The free end of the top is enlarged, which is called the bottom of the seminal vesicle. The narrow and straight lower end of the seminal vesicle is called excretory duct. Because of the special structural of seminal vesicle, once inflammation occurred, seminal vesicle fluid discharge is congested, bacteria is blocked in and very difficult to clear thoroughly. If let the condition develop and delay, serious complications such as secondary infertility will occur, result in a life-long regret for patient. So, to prevent the seminal vesiculitis from getting prolonged, both acute and chronic seminal vesiculitis should be thoroughly treated. It should also be pointed out that, seminal vesiculitis, especially the chronic seminal vesiculitis accompanied with chronic prostatitis, is much easier to prolong and relapse. Seminal vesiculitis treatment should be persistent. Doctors should help patients to establish confidence and encourage them to overcome the disease.
