ULTRASTRUCTURAL AND DNA FRAGMENTATION ANALYSES IN SWIM-UP SELECTED HUMAN SPERM
Archives of Andrology, 2006Seventeen sperm samples were evaluated by transmission electron microscopy (TEM) before and after swim-up separation. DNA-fragmentation was tested by terminal d-UTP nick end labeling (TUNEL) in unselected and selected semen samples, and the results were analyzed in relation to sperm ultrastructural characteristics detected by TEM.

[Spermatic fertilization capacity after swim-up spermatozoa recovery technique].
Archivos espanoles de urologia, 2006To investigate sperm quality before and after swim up in infertile patients, and to compare it with a fertile men population.Semen samples from 55 patients consulting at the infertility services of the Hospitals "Centenario" in Rosario and "Eva Perón" in Gro Baigorria were collected and analyzed accordingly with the WHO guidelines.

Artificially selected human sperm morphology after swim-up processing
Canadian Journal of Zoology, 2012The swim-up technique is a clinical practice used to select highly motile sperm cells from patient ejaculates to use in assisted fertilization. The aim of this study was to investigate whether the length of different sperm-cell components is related to gamete function. Thus, we explored whether swim-up technique selects for longer sperm cells than mean

Sensitivity of Guadalupe Bass Swim-up Fry to Hyperoxia
North American Journal of Aquaculture, 2017Abstract Hatchery-reared fingerling Guadalupe Bass Micropterus treculii are stocked into central Texas rivers to restore threatened populations and combat hybridization with Smallmouth Bass M. dolomieu. Fry survival in hatchery rearing ponds has declined by more than 50% in recent years, and pilot investigations indicated that exposure ...

Dextran/Swim-Up Procedure for Ram Sperm Selection
The procedures for separating spermatozoa from seminal plasma are frequently applied in reproductive technologies. Most of these procedures include centrifugation steps, which have detrimental effects on ram spermatozoa. We developed a special dextran/swim-up technique without centrifugation which allows the recovery of highly motile and viable ram ...Rosaura, Pérez-Pe +3 more

Increased recovery of swim-up spermatozoa by application of “antigravitational” centrifugation
Fertility and Sterility, 1999To compare the quantity and quality of sperm recovered following the 10-minute application of an antigravitational force during the swim-up procedure with the standard 60-minute swim-up (SSU) procedure.Prospectively controlled in vitro study.Private andrology laboratory and hospital-based infertility practice.Equal aliquots of semen were evaluated ...

Choline Requirement of Swim-Up Rainbow Trout Fry
The Progressive Fish-Culturist, 1991Abstract Triplicate 150-fish lots of first-feeding fry of rainbow trout (Oncorhynchus mykiss; initial mean weight, 0. 12 g) were fed casein–gelatin-based diets containing 0, 200, 400, 800, 1,000, 2,000, 4,000, or 8,000 mg choline/kg of feed for 12 weeks to determine their need for dietary choline.

Enhanced recruitment of motile spermatozoa by prostasome inclusion in swim-up medium
Human Reproduction, 1994Prostasomes, which are prostate-derived organelles, were purified from human seminal plasma for inclusion in Earle's balanced salt solution (EBSS) medium with or without human serum albumin. These media were used for swim-up experiments and the subsequent analyses of sperm motility parameters at different incubation times.

In vitro fertilization outcome: glass wool-filtered sperm versus swim-up sperm
Fertility and Sterility, 1989At present, most in vitro fertilization (IVF) programs use a swim-up procedure for sperm preparation. This method mimics the in vivo selection of motile sperm by cervical mucus. Filtration through a column of glass wool, on the other hand, may result in recovery of more viable sperm from an ejaculate with relatively poor quality as compared with the ...
