Journal ArticleDOI
Microdeletions in the Y chromosome of infertile men
Jon L. Pryor,Marijo Kent-First,A. Muallem,A. Muallem,A.H. Van Bergen,W. E. Nolten,L. Meisner,Kenneth P. Roberts +7 more
TL;DR: A small proportion of men with infertility have Y-chromosome microdeletions, but the size and position of the deletions correlate poorly with the severity of spermatogenic failure, and a deletion does not preclude the presence of viable sperm and possible conception.
Journal ArticleDOI
Mechanical property characterization of mouse zona pellucida
TL;DR: In this article, a microelectromechanical system-based multiaxis cellular force sensor has been used to conduct mouse ZP force sensing, establishing a quantitative relationship between applied forces and biomembrane structural deformations on both mouse oocytes and embryos.
Journal ArticleDOI
Defining regions of the Y-chromosome responsible for male infertility and identification of a fourth AZF region (AZFd) by Y-chromosome microdeletion detection.
Marijo Kent-First,Ariege Muallem,John Shultz,Jon L. Pryor,Kenneth P. Roberts,W. E. Nolten,L. Meisner,A. Chandley,G. Gouchy,L. Jorgensen,T. Havighurst,J. Grosch +11 more
TL;DR: To thoroughly analyze the AZF region(s) and any correlations that may be drawn between genotype and phenotype, the design of nine multiplex PCR reactions derived from analysis of 136 loci is described, which include four populations of males with these STSs.
Journal ArticleDOI
The adolescent varicocele: what's new with an old problem in young patients?
TL;DR: The purpose of this review is to present the most current information on the adolescent varicocele, provide guidelines on managing this perplexing problem in the asymptomatic adolescent male, and stimulate future research about the enigmatic relationship between thevaricocele and its effects on testicular growth and function.
Journal ArticleDOI
Inhibition of Capacitation-Associated Tyrosine Phosphorylation Signaling in Rat Sperm by Epididymal Protein Crisp-1
TL;DR: Capacitation results in the acquisition of hyperactivated motility, changes in the properties of the plasma membrane, including changes in proteins and glycoproteins, and acquisition of the ability to undergo the acrosome reaction.
