OBJECTIVE To analyze whether the presence of congenital anomalies of the genitourinary system that are accompanied by specific types of cancer and predispose patients to many complications, including infection, obstruction, stasis, calculus formation, and impaired renal function, could help in the diagnosis of the primary site of a metastatic tumor. CASE PRESENTATION We report a case of a 58-...

BACKGROUND Degenerative effects of critical regulators of reproduction, the kisspeptin peptides, on cellular aspects of sexually immature male gonads are known but similar information on accessory sex glands remain elusive. METHODS Prepubertal laboratory rats were injected kisspeptin-10 at three different dosage concentrations (10 pg, 1 ng and 1 microgram) for a period of continuous 12 days a...

Local application of actinomycin D does not detectably modify growth response of the chick comb to androgens. The mode of action of androgens on chick comb (a connective-tissue organ) appears to differ from their action on epithelial-tissue organs such as seminal vesicles and prostate.

In endemic regions, Mansoni schistosomiasis is responsible for high morbidity-mortality rates due to diseases associated with infestation of the hepatic system. Genital involvement caused by Mansoni schistosomiasis is rare. We report the first case of Mansoni schistosomiasis in the seminal vesicle, which was diagnosed incidentally by means of histopathological study of the prostate and seminal ...

OBJECTIVES To observe the phenomenon of human ejaculation dynamically using color Doppler ultrasonography. METHODS Human ejaculation was observed using transrectal color Doppler ultrasonography in a healthy man and a patient with retrograde ejaculation. Ejaculation was induced manually with audiovisual sexual stimulation. The ejaculatory phenomenon was analyzed and compared with that of retro...

BACKGROUND Benign ectopia of prostatic glandular tissue in the seminal vesicles is rare with only three prior cases reported in the literature. Prostate cancer, arising within prostatic ectopia in the seminal vesicles, has never been described and therefore presents a challenge in both diagnosis and management. CASE PRESENTATION Herein, we report a rare case of prostatic adenocarcinoma in ect...
