USING EPIDIDYMAL AND TESTICULAR SPERM FROM AZOOSPERMIC MEN: THE CLEVELAND CLINIC EXPERIENCE Mehmet Oder, Ramadan A Saleh, Namita Kattal, Mohamed A Bedaiwy, Anthony J Thomas, Ashok Agarwal, Cleveland Clinic Foundation Objective: Sperm retrieval from testis and epididymis, combined with ICSI, has significantly enhanced the chances of azoospermic men to father their own genetic offspring. The impa...

leptin is secreted mainly by fat, which is involved in energy metabolism and reproduction. leptin and itsreceptor (ob-r) have been detected in human spermatozoa and testis, thus it can be concluded leptin involves in male physiology. the goal of this study was determination of the presence of leptin receptor mrna in the ram testis, epididymis and spermatozoa by reverse transcription polymerase ...

Previous studies have shown that epididymal epithelium and its secretions are critical for sperm maturation. These secretions contain many glycoconjugates with sialic acid terminal sugar. This terminal sugar by interveining in cellular interactions and masking surface receptors, has an important role in sperm maturation and protection. Moreover lectins have been employed as useful probes to det...

  SUMMARY This study was conducted to shed light on to the factors contributing to fertilizing ability of the caput epididymal spermatozoa. In this content, it should be stated that seminal plasma am! epididymal fluid of most mammalians contains inhibitory factors connected to spermatozoa surface. To do this, components of different regions of mouse epididymis centrifuged and a given volume o...

Primary epididymal adenocarcinoma (PEA) is exceedingly rare. Only 22 cases had been published worldwide by 2008; nearly 80% of these cases were reported before 2007. In order to investigate the current clinical status of PEA, we search for relevant literatures with "epididymis and adenocarcinoma" and "epididymal and adenocarcinoma" as keywords published between January 1997 and November 2017 in...

BACKGROUND Epididymal inflammatory myofibroblastic tumor, also known by various other synonyms is a rare benign disease. Only eight cases have been reported to date. The most common presentation is a scrotal mass of variable duration. For a scrotal mass it is difficult to distinguish a benign or malignant etiology, in addition to the origin whether from testis or epididymis. As a result the def...

Most aspects of reproductive function including spermatogenesis, oocyte growth and maturation, early embryonic development, fetal and placental growth, and lactation can be affected by thermal stress. Furthermore, it has been shown that oxidative stress involves in the pathology of thermal stress. Therefore, the aim of this study was to investigate the impacts of thermal stress on the ovine mat...
