Bisphenol-A(BPA) is a member of alkylphenol family, and shows adverse effects including reduced fertility, reproductive tract abnormalities, metabolic disorder, cancer induction, neurotoxicity and immunotoxicity. In the present study, we conducted Hershberger assay to evaluate whether the two candidates to replace BPA have androgenic or antiandrogenic activity. The assay was carried out using immature castrated Sprague-Dawley male rats. After 7 days of the surgery, testosterone propionate (TP, 0.4 mg/kg/day) and test materials (low dose, 40 mg/kg/day; high dose, 400 mg/kg/day) were administered for 10 consecutive days by subcutaneous (s...

The origin of the posterior scrotal nerve is considered to be the bilateral pudendal nerves but the course to the midline is still obscure. Using 5 late-stage human male fetuses, we identified the single nerve through the intramuscular midline septum of the bulbospongiosus and the bilateral nerves along the left and right sides of the septum. Thus, the posterior scrotal nerve showed a variation: a single midline trunk or bilateral nerves. Branches of the bilateral pudendal nerves ran medially between the muscle and Cowper's gland and, at the midline area, they joined or associated closely...

Background: Cowper's syringocele is a rare condition, uncommon in the adult population. It is more common in the pediatric population. Patients could be asymptomatic or present with irritative and/or obstructive symptoms. Ultrasonography (US) of perineal region, pelvis MRI, or urethrography are the most often used diagnostic modalities. Surgical treatment is indicated in all symptomatic patients. Endoscopic approach is preferred over open surgery. Unroofing of syringocele with cold knife or holmium yttrium aluminium garnet (YAG) laser is effective treatment...

The present report describes a case of multicystic degeneration of the Cowper's gland in a 1.3-year-old purebred Large White intact boar with reduced fertility in Switzerland. Based on the case history, a general physical examination, an andrological investigation and a transrectal ultrasonography combined with a subsequent thorough pathological examination including histology a multicystic degeneration of the Cowper's gland were diagnosed. The case indicates that cystic degeneration of the bulbourethral gland should be contemplated in the differential diagnoses of andrological disorders even though it has not been described in pigs so far...

Syringocele or dilatation of the duct of the bulbo-urethral (Cowper's) gland is usually of congenital origin but can be acquired. It is a very rare deformity, <10 cases have been reported in literature. The main objective is to describe an additional case of syringocele of Cowper's glands and review the literature. An 18-month-old infant presented with a history of acute urinary retention 3 days after birth and a cystostomy was done. Voiding cystourethrogram was normal and cystourethroscopy showed a syringocele...

Cystic dilatation of bulbourethral gland ducts (Cowper's gland syringocele) is a rare abnormality. The condition has been described among pediatric populations, but it is uncommon in adults. It can be asymptomatic or present with obstructive and irritative urinary symptoms. We report a case of a symptomatic imperforate Cowper's syringocele in a young patient that was successfully managed with transurethral unroofing of the cyst.

The diagnosis of prostate cancer is made based on the architecture of the glandular proliferation and nuclear atypia, but some normal structures (seminal vesicle, Cowper's glands, prostatic central zone) or nonneoplastic proliferative lesions can mimic carcinoma. Of the 3 patterns of prostate cancer--solid, cribriform, and microglandular, the microglandular pattern is the one that imitates carcinoma most frequently on needle biopsy. The demonstration of basal cells can be the best method to identify these prostate cancer mimickers...

The impact of exogenic testosterone (T): 1.5 and 3.0 mg/ and 19-nortestosterone 17-decanoate (ND): 1.5 and 7.5 mg/ in castrated male rats was evaluated based on: (a) weight increase of the androgen target tissues, respecting the Hershberger methodology; (b) the 17α and β-testosterone, 17 α and β-estradiol and 17 α and β-nortestosterone levels using the GC-MS/MS technique; and (c) observation of the serum free thyroxine levels (T4). Results revealed that T and ND significantly increased the weight of androgen target tissues as follows: ND was more influential on seminal vesicles, levator ani-bulbocavernosus muscle (LABC) and Cowper's glands and T (at a dose of 3...

The explosive 3-nitro-1,2,4-triazol-5-one (NTO) is an insensitive formulation developed to replace high energetics that are susceptible to accidental detonation from heat, shock, and impact. Although studies have shown NTO to be nontoxic at acute exposures, recent subacute and subchronic tests have demonstrated effects on testes and subsequent sperm production in rats. This study assessed endocrine disruption as a potential mechanism for these reproductive effects via the Hershberger and uterotrophic bioassays...

The present study examines the structure and ultrastructure of the bulbourethral glands in 10 sexually matured male greater cane rats raised in captivity. Following anaesthesia, the rats were perfusion-fixed transcardially and the bulbourethral glands dissected out. Upon morphologic and morphometric analysis, the Cowper's glands were observed to have an average volume of 0.24±0.08 ml, a diameter of 6.3±0.6 mm and weighs 0.199±0.06 g. The paired, gourd-shaped tubuloalveolar glands were surrounded by dense connective tissues and separated into lobules by capsular septae...

Cancer of Cowper's gland is a very rare cancer. This case represents the 9th case in the medical literature. As such, there are no phase II or phase III trials to guide treatment. In this article, we report the successful treatment of a patient over a 7-year period guided solely by molecular profiling. Through multiple cycles to treatment, the cancer was controlled using drugs targeting c-kit, as the cancer steadily increased the expression of c-kit. This report also documents the use of a novel drug combination based on sunitinib that was well tolerated and may warrant testing in other c-kit-dependent cancers...

We report what to our knowledge is the first case of a giant multicystic cystadenoma of the Cowper's glands. An otherwise healthy 41-year-old man presented with acute urinary retention. Physical examination showed a perineal mass. Different imaging techniques demonstrated a multicystic tumor and en bloc excision was performed. Histological evaluation showed that the tumor arised from the bulbourethral glands; immunohistochemistry proved positive staining for high molecular weight cytokeratin. CASE HYPOTHESIS: Cystic tumors in the pelvis can arise from different structures...

The diagnosis of prostate cancer (PCa), especially limited adenocarcinoma on needle biopsy, is often challenging. Before making diagnosis of PCa, it is prudent for the pathologist to consider different benign patterns that may lead to a false positive interpretation. Histoanatomic structures such as seminal vesicles, Cowper's glands and paraganglia along with hyperplasia, atrophy with its different patterns and adenosis may generate difficulties in differential diagnosis. Furthermore, inflammatory processes and post-treatment changes may cause problems...

This case report describes a tubulosquamous polyp resembling a penis in the uterine cervix. A 34-yr-old, gravida 0, para 0, woman showed an 18 × 8 × 5 mm polypoid lesion in the uterine ectocervix. The polyp had a penis-like appearance; the tip looked like glans penis and the middle portion resembled the shaft of the penis. Its surface was covered by squamous epithelium, and tissues resembling those of a urethra, corpus spongiosum penis, and external orifice urethra were observed. Foreskin-like tissues were also observed, although a corpus cavernosum penis was not seen...
