A microfluidic sperm-sorting device reduces the proportion of sperm with double-stranded DNA fragmentation

La fragmentación del ADN espermático se puede producir en una (ssSDF) o en ambas (dsSDF) cadenas del ADN, estos daños están relacionados con dificultades para lograr un embarazo de forma natural y abortos espontáneos recurrentes, respectivamente. Las técnicas que se utilizan con más frecuencia para seleccionar espermatozoides requieren de centrifugación, lo que puede aumentar el […]

Alkaline and neutral Comet assay profiles of sperm DNA damage in clinical groups

The analysis of sperm DNA fragmentation has become a new marker to predict male infertility, and many techniques have been developed. The sperm Comet assay offers the possibility of differentiating single- and double-stranded DNA (ssDNA and dsDNA) breaks, which could have different effects on fertility. The objective of this study was to perform a descriptive […]

Comprehensive analysis of sperm DNA fragmentation by five different assays: TUNEL assay, SCSA, SCD test and alkaline and neutral Comet assay

Sperm DNA fragmentation (SDF) is becoming an important test to assess male infertility. Several different tests are available, but no consensus has yet been reached as to which tests are most predictive of infertility. Few publications have reported a comprehensive analysis comparing these methods within the same population. The objective of this study was to […]

Comparative study of fertility parameters 2

Abstract The cryopreservation of spermatozoa has the main purpose of preserving male fertility. However, current preservation techniques have shown to produce lesions in the structure and alter sperm functions, probably due to the production of reactive oxygen species (ROS) during cryopreservation. To overcome the damage provoked by ROS, we introduced a novel antioxidant called EmbryORP® in […]

Comparative study of fertility parameters in vitrified human spermatozoa in the presence or absence of EmbryORP ® : A novel antioxidant

Abstract The cryopreservation of spermatozoa has the main purpose of preserving male fertility. However, current preservation techniques have shown to produce lesions in the structure and alter sperm functions, probably due to the production of reactive oxygen species (ROS) during cryopreservation.
