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 ...

Swim-up procedure selects spermatozoa with longer telomere length
Mutation Research - Fundamental and Molecular Mechanisms of Mutagenesis, 2010Telomere length and sperm DNA fragmentation were determined in sperm samples from 27 patients, using a quantitative PCR (Q-PCR) assay and the Sperm Chromatin Dispersion (SCD) test, respectively. Comparisons of the samples before and after swim-up processing demonstrated that this procedure selects a sperm population with longer average telomere size ...

A Controlled Study for Gender Selection Using Swim-Up Separation
Gynecologic and Obstetric Investigation, 1999<i>Objective:</i> To evaluate the success for gender selection using a sample of semen separated by a modified swim-up technique. <i>Design:</i> We retrospectively compared the gender outcome of two treatments (A and B) for either a male or female offspring with those who conceived spontaneously.

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

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.

Effect of Motile Sperm Count After Swim Up on Outcome of Intrauterine Insemination
Fertility and Sterility, 1997To analyze the prognostic value of motile sperm count after swim-up in IUI with husband's sperm in a large group of subfertile couples.Retrospective study.University hospital.Nine hundred two couples undergoing 3,037 treatment cycles.Intrauterine insemination with husband's sperm after swim-up was performed after mild ovarian stimulation with ...

Choosing fertilization method by analyzing sperm morphology or by performing swim-up preparation
Acta Obstetricia et Gynecologica Scandinavica, 2006AbstractBackground. Evaluation of sperm morphology has been used as a screening method for choosing between intracytoplasmic sperm injection (ICSI) and conventional in vitro fertilization (IVF). However, sperm morphology analysis is a time‐consuming and often subjective scoring method, and may lead to an unnecessarily large proportion of invasive and ...

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.

Clinical application of the swim-up and washing of human spermatozoa.
International journal of fertility, 1990Artificial insemination with husband's semen is one of the treatments in cases of male infertility. A technique for swim-up and washing sperm is described. A special device was used for introduction of sperm into the uterus. Sperm density after treatment by swim-up and washing of sperm was lower than in the pretreatment specimens, but sperm motility ...
