Background
The ubiquitin ligase HECT, UBA, and WWE domain‐containing E3 ubiquitin protein ligase 1 is essential for the establishment and maintenance of spermatogonia. However, the role of HECT, UBA, and WWE domain‐containing E3 ubiquitin protein ligase 1 in regulating germ cell differentiation remains unclear, and clinical evidence linking HECT, UBA, and WWE domain‐containing E3 ubiquitin protein...
Cryopreservation of small quantities of human spermatozoa whilst maintaining adequate post‐thawing motility has been found an essential challenge for male fertility preservation. Therefore, the study used an effective, and convenient rapid‐freezing method to freeze small amounts of human spermatozoa by adding self‐prepared cryoprotectant (SPC) without animal component. In the feasibility experiment,...
To evaluate the effect of surgical intervention on catch-up growth as determined by a decreased testicular volume discrepancy in children and adolescents with varicocele. A systematic search was performed using MEDLINE and the PubMed database and cross-referenced as of October 28, 2011 using the terms “varicocele,” “children,” “adolescent,” “surgery,” and “testicular volume.” All relevant studies...
Objectives: To determine the effect of surgical varicocele repair in improving testicular Leydig cell function as shown by increased testosterone production.
Methods: Eligible studies were searched in Medline and the Pubmed database, and cross‐referenced as of 31 May 2011 using the terms “varicocele,”“testosterone” and “surgery.” The database search, quality assessment and data extraction were independently...
