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

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. We generated a sox2 KO zebrafish using TALEN and found that the posterior chamber of the swim bladder was ...

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 Genet
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

Warm-Up and Performance in Competitive Swimming [PDF]

Sports Medicine, 2013
Warm-up before physical activity is commonly accepted to be fundamental, and any priming practices are usually thought to optimize performance. However, specifically in swimming, studies on the effects of warm-up are scarce, which may be due to the swimming pool environment, which has a high temperature and humidity, and to the complexity of warm-up ...

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 ...
