Zebrafish sox2 Is Required for the Swim Bladder Inflation by Controlling the Swim-Up Behavior. [PDF]
Zebrafish, 2023 The swim bladder functions to maintain the fish balance at a certain position under water. Although the motoneuron-dependent swim-up behavior is important for swim bladder inflation, the underlying molecular mechanism remains largely unknown.

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

Sperm swim-up techniques and DNA fragmentation [PDF]
Human Reproduction, 2001 Swim-up techniques for sperm separation may have detrimental effects on sperm DNA. We wished to determine whether the normal swim-up method with centrifugation used in our laboratory, which involves a centrifugation step, was harmful to sperm compared with swim-up without centrifugation.Semen samples were obtained from patients undergoing IVF or ...

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 ...

Comparison of Sperm Motility between The Swim-up and Swim-down Methods
Siriraj Medical Journal, 2020 The objective of this study was to compare two methods for the extraction of high motility sperm; the swim-up and swim-down techniques. The result showed that both methods produced greater sperm motility than the original semen. The motility of the sperm
