Relationship between DNA damage and sperm head birefringence
(Elsevier B.V., 2011-06-01)
Birefringence or double refraction is the decomposition of a ray of light into two rays when it passes through an anisotropic material such as quartz. Sperm cells have been demonstrated to be optically anisotropic. The ...

Significance of extruded nuclear chromatin (regional nuclear shape malformation) in human spermatozoa: implications for ICSI
(Wiley-Blackwell, 2011-12-01)
The aim of this study was to determine the extent of DNA fragmentation and the presence of denatured single-strand or normal double-strand DNA in spermatozoa with extruded nuclear chromatin (ENC) selected by high magnification. ...

Association of age with sperm DNA fragmentation Aumento del daño en el ADN espermático en varones mayores de 40 años
(2011)
Background: There is an association between aging and an increased number of sperms with alterations in nuclear DNA. Aim: To study the association between age and fragmentation of sperm DNA. Material and Methods: Sixty two ...
Screening and characterization of sex-specific DNA fragments in the freshwater fish matrinch, Brycon amazonicus (Teleostei: Characiformes: Characidae)
(Springer, 2012-10-01)
The matrinch Brycon amazonicus, a commercially important freshwater fish resource, has no heteromorphic sex chromosomes so far described. In the present study, we performed a screening of sex-associated DNA markers in this ...
