Action of swim-up and caffeine on equine frozen sperm. [PDF]
Anim Reprod, 2022 Cryopreservation of equine semen is crucial to semen commercialization. However, it reduces sperm motility and longevity. Thus, sperm selection methods and addition of motility-activating substances to sperm, such as caffeine, may improve sperm quality of equine frozen semen.

Effect of zinc on sperm recovered by swim-up. [PDF]
J Assist Reprod GenetZinc 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

Comparison of the effect of different media on the clinical outcomes of the density-gradient centrifugation/swim-up and swim-up methods. [PDF]
Clin Exp Reprod Med, 2015 Sperm must be properly prepared in in vitro fertilization (IVF)-embryo transfer (ET) programs in order to control the fertilization rate and ensure that embryos are of high quality and have appropriate developmental abilities. The objective of this study was to determine the most optimal sperm preparation method for IVF.Patients less than 40 years of ...

Evaluation of ram semen motility by a swim-up technique [PDF]
Reproduction, 1993 The turbidity formed as ram spermatozoa swam up into a clear medium was measured using a colorimeter and this was used as an objective index of sperm motility. Wavelengths of 470–475 nm yielded higher optical densities (OD) than did 520–640 nm. The recommended distance between the light beam and semen–medium interface, and operation temperature were 5 ...

A comparison of the swim-up procedure at body and testis temperatures [PDF]
Journal of Assisted Reproduction and Genetics, 2008 A range of different sperm preparation methods have been developed during the last two decades following a rapid increase of clinics using assisted reproductive technologies (ART). Among these methods, swim-up procedures and density gradient centrifugation are widely used techniques for sperm preparation [1–3]. The swim-up from a washed sperm pellet

Semen preparation by standard swim-up versus swim-up with test yolk buffer incubation in intrauterine insemination: a randomized study [PDF]
Human Reproduction, 1998 In order to compare the standard swim-up semen preparation with and without test yolk buffer (TYB) incubation in intrauterine insemination (IUI), we conducted a prospective multicentre randomized trial. A total of 121 infertile couples with male factor (n = 52) or unexplained infertility (n = 69) was randomly assigned to two groups following ovulation ...

Effect of the pH in the enrichment of X or Y sex chromosome-bearing sperm in bovine [PDF]
Veterinary World, 2019 Background and Aim: Studies have shown that the pH of the vagina during the course of fertilization may influence the migration of X- and Y-bearing spermatozoa and thus leading to skewness in the sex of the offspring. Hence, this study was carried out to

Analysis of sperm separation protocols for isolating cryopreserved human spermatozoa
Reproduction and Fertility, 2023 Sperm cryopreservation is a valuable tool for the long-term preservation of male fertility. Thus, determining the optimal technique for isolating spermatozoa post-thaw is vital to ensure recovery of the highest quality spermatozoa with minimal iatrogenic
