Cystadenomas of the seminal vesicles are extremely rare. Here, we report a large seminal vesicle cystadenoma. A 37-year-old man presented a 6-month history of haemospermia, 10 days of Lower Urinary Tract symptoms (LUTSs) and gross haematuria. Transabdominal ultrasonography, computed tomography and magnetic resonance imaging were performed and revealed a large solid-cystic pelvic mass morphometrically measured 7.0 cm × 11.9 cm × 8.6 cm on the right seminal vesicle, which caused hydronephrosis of the right kidney...

To verify if quality of spermatozoa from men with testicular germ cell tumours is better before or after orchiectomy. This prospective study was carried out including 24 patients with testicular germ cell tumours, who provide one semen sample before they were submitted to unilateral orchiectomy and one other semen sample 30 days after the surgery. After collection by masturbation and liquefaction, an aliquot of the semen sample was used for semen analysis and another was used to evaluate sperm mitochondrial activity, DNA fragmentation and acrosome integrity...

Chronic inflammatory conditions of the genital tract are still unsatisfactorily recognised in the workup of male infertility due to inappropriate definitions and inconsistent diagnostic criteria. The most popular term used for description of both, infections and inflammation in the genital tract is MAGI (male accessory gland infection). In asymptomatic patients, the diagnosis is primarily based on leucocytospermia (i.e., more than 1 million peroxidase-positive leucocytes per ml ejaculate), although ongoing infections should be identified and distinguished from post-infectious or non-infectious inflammatory disease...

We explored whether platelet-derived growth factor (PDGF)-BB regulates corpus cavernosum smooth muscle cell gap junctions and can ameliorate erectile dysfunction and how it modulates connexin43 (CX43) after bilateral cavernous neurectomy. Primary cultured rat corpus cavernosum smooth muscle cells were treated with PDGF-BB with or without a PDGFR inhibitor, Akt siRNA or the depletion or promotion of β-catenin. PDGF-BB improved CCSMCs gap junction coupling and increased CX43 and PDGFRβ expression; inhibition of PDGFR activity down-regulated CX43 and decreased Akt and nuclear β-catenin...

In recent years, there has been significant increase in mobile phone users. With this, health concerns associated with the exposure to electromagnetic radiation are also increasing. Continuous exposure to electromagnetic (EM) radiation generated from mobile phone is one of the probable reasons behind increasing male infertility. EM radiations induce oxidative stress that leads to numerous changes in reproductive parameters. With this hypothesis, we studied the effect of 3G mobile phone radiations on the reproductive system of male Wistar rats...

Individuals who regularly exercise utilise dietary supplements to enhance their exercise routine and to increase lean mass. Branched-chain amino acids (BCAAs) are a popular supplement and have been shown to produce a number of beneficial effects in rodent and human models. Therefore, in the present study, the effect of exercise and/or BCAA on sperm parameters and testes tissue was assessed. C57BL6 male mice were divided to six groups; Control, Exercise (Exc), BCAA (consumes 20 mg BCAAs), BCAA+ (consumes 60 mg BCAAs), BCAA/Exc (consumes 20 mg BCAAs during aerobic training) and BCAA+/Exc (consumes 60 mg BCAAs during aerobic training)...
