Sperm selection with density gradient centrifugation and swim up: effect on DNA fragmentation in viable spermatozoa. [PDF]
Subjects increasing sperm DNA fragmentation (sDF) during Density Gradient Centrifugation (DGC), a common sperm selection procedure in Assisted Reproduction Techniques (ARTs), experience a 50% lower probability of pregnancy. Hence, identification of these

The motility-based swim-up technique separates bull sperm based on differences in metabolic rates and tail length. [PDF]
Swim-up is a sperm purification method that is being used daily in andrology labs around the world as a simple step for in vitro sperm selection. This method accumulates the most motile sperm in the upper fraction and leaves sperm with low or no motility

Effect of zinc on sperm recovered by swim-up. [PDF]
Zinc is known to influence chromatin stability, motility and protection against oxidative stress. While swim-up remains the preferred method for selecting sperm in Assisted Reproductive Technologies (ART), concerns arise regarding sperm DNA fragmentation associated with this procedure. Given zinc's significant role in protecting sperm DNA integrity and

Sperm DNA fragmentation and sex chromosome aneuploidy after swim-up versus density gradient centrifugation. [PDF]
Objective The aim of this study was to compare the efficacy of swim-up and density gradient centrifugation (DGC) for reducing the amount of sperm with fragmented DNA, sex chromosome aneuploidy, and abnormal chromatin structure. Methods Semen samples were

A Comparison of Swim-up and Simple Swim-up Methods for the Extraction of High Motility Sperm
The objective of this study was to compare two methods for the extraction of high motility sperm; swim-up and simple swim-up technique. The results were comparable in concentration, motility and morphology.

Semen preparation methods and sperm telomere length: density gradient centrifugation versus the swim up procedure. [PDF]
Previous studies have shown that both density gradient centrifugation (DGC) and swim up (SU) procedures can select spermatozoa with longer telomeres for assisted reproduction techniques (ART). However, it is unknown which approach is more effective.

A new micro swim-up procedure for sperm preparation in ICSI treatments: preliminary microbiological testing. [PDF]
Objective This study aimed to assess the levels of microbial contamination in semen samples before and after the micro swim-up (MSU) procedure in intra-cytoplasmic sperm injection (ICSI). The new method is an upgrade to the classic wash swim-up procedure.
