Objective: To describe the aetiology and efficacy of the treatment of persistent and recurrent hemospermia as a novel technique of transurethral seminal vesiculoscopy. Methods: The clinical data of 290 patients with persistent and recurrent hemospermia (a course of hemospermia persisting more than 6 months) from multiple medical center of South China were analyzed retrospectively. The age range...

We isolated the major protein of apparent Mr of 15,000-16,000 from seminal plasma as well as from seminal vesicle secretion of bull and proved by amino acid analysis and tryptic peptide mapping that the two proteins were identical. An antiserum against this major protein was employed to quantitate and identify the major protein in seminal plasma as well as seminal vesicle secretion. The antiser...

Introduction. Zinner syndrome is a rare congenital malformation characterized by ipsilateral renal agenesis or hypoplasia, seminal vesicle cysts, and ejaculatory duct obstruction. Patients are usually asymptomatic develop unspecific symptoms. Case Report. We present case of 22-year-old male patient who presented with painless terminal hematuria. The denied trauma other urinary tract Magnetic re...

The three Pegoscapus species present the same internal reproductive tract features comprising testes with a single testicular tubule, seminal vesicles, vasa deferentia, accessory glands and an ejaculatory duct. The seminal vesicle shows two morphologically distinct portions although they do not resemble the separate chambers found in other Chalcidoidea. The anterior portion of the seminal vesic...

Whereas in all other vertebrates the Müllerian ducts of genetic males are aborted during development, under the influence of Müllerian-inhibiting substance, in the caecilian amphibians they are retained as a pair of functional glands. It has long been speculated that the Müllerian gland might be the male accessory reproductive gland but there has been no direct evidence to this effect. The pres...

INTRODUCTION Primary tumors of seminal vesicles are rare and only a few cases have been reported. Diagnosis is difficult due to the absence of early clinical signs. Prognosis is generally poor. CASE PRESENTATION We present the case of a 70-year-old Caucasian man with a seminal vesicle mass and concomitant lymph node metastasis detected by computed tomography and body positron emission tomogra...

We report a case of male infertility with low ejaculate volume and azoospermia. An infected seminal vesicle cyst that induced partial obstruction of the seminal duct system was diagnosed by transrectal ultrasound. After transrectal cystic aspiration and decompression, a normal spermogram was obtained.

BACKGROUND Yolk sac tumor (endodermal sinus tumor) is a rare malignant germ cell tumor arising in the testis or ovary. Extragonadal yolk sac tumor is even rarer and has only been described in case reports. Due to the rarity of the tumors, the appropriately optimal treatment remains unclear. We report a case of yolk sac tumor in the seminal vesicle. CASE A 38-year-old Asian male presented with...
