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 ...

Investigation in real time of the effect of gravitation on human spermatozoa and their tendency to swim‐up and swim‐down [PDF]
International Journal of Andrology, 1993 SummaryTo investigate in real time if and how natural gravity affects rates of swim‐up and swim‐down of human spermatozoa, samples of motile or immobilized spermatozoa in a sealed mini‐chamber were placed vertically on a 90° tilted microscope. The mode of their sedimentation, as well as the difference in the rate of their swimming up and down, were ...
