Because of the presence of a high density of vasopressin receptors in the epithelial cells of porcine seminal vesicles similar to the V2 vasopressin receptors of renal tubules, human seminal vesicles and kidney were investigated using quantitative binding and adenylate cyclase studies. Tissues were obtained at surgery from 17 patients with urologic diseases. A homogeneous class of vasopressin b...

The mouse seminal vesicle shape (svs) mutation is a spontaneous recessive mutation that causes branching morphogenesis defects in the prostate gland and seminal vesicles. Unlike many other mutations that reduce prostatic and/or seminal vesicle branching, the svs mutation dramatically reduces branching without reducing organ growth. Using a positional cloning approach, we identified the svs muta...

The comparison of measurements of fibronectin and lactoferrin in ejaculates from vasectomized men, subjects with functional deficiency or aplasia of the seminal vesicles, and reference subjects provided evidence that both the fibronectin and the lactoferrin in human seminal fluid originate from the seminal vesicles and the ampullae. The fibronectin is incorporated in the framework of the semina...

2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) has been shown to alter male reproductive development of laboratory animals through in utero and lactational exposure. As a result of exposure, the accessory glands of the male reproductive tract, including the seminal vesicle, are decreased in size as determined by total weight of the tissue. Analysis of seminal vesicle weights over time suggests that...

We have recently demonstrated the expression of leptin and leptin receptor (Ob-R) isoforms a, b, c, e and f in the rat seminal vesicles and prostate. The aim of the present study was to provide a semiquantitative real-time PCR estimation of leptin/Ob-R isoform mRNA expression in the seminal vesicles and individual components of rat prostate, and to ascertain the in vitro effects of leptin on pr...

OBJECTIVE To determine through preoperative serum PSA level, Gleason score on biopsy and percentage of fragments affected by tumor on biopsy, the probability of involvement of the seminal vesicles. MATERIALS AND METHODS During the period between March 1991 to December 2002, we selected 899 patients undergoing radical prostatectomy for treatment of localized prostate adenocarcinoma. The analyz...

A 32-year-old man presented with primary infertility. He had azoospermia with low volume ejaculate. Physical examination was normal. Transrectal ultrasonography (TRUS) revealed grossly dilated seminal vesicles. No other genitourinary tract abnormality was noted. He underwent TRUS-guided aspiration of the seminal vesicles with simultaneous instillation of contrast media and methylene blue dye in...

Mucosal spreading of urothelial tumors to the seminal vesicles is very rare. We experienced a case of mucosal involvement of the seminal vesicles by a bladder tumor in a 72-year-old man. The patient had a history of transurethral resection for invasive urothelial carcinoma of the bladder 8 years previously. Radical cystoprostatectomy was performed owing to recurrent and multiple urothelial carc...
