Quality Comparison of Three Disposable Sperm Cell Counting Chambers
AND CONCLUSION In this study various quality aspects of the CellVision, Leja, and MicroCell disposable sperm cell counting slides were investigated. The height of the chambers was determined using interferometric spectrometry. The average heights of the Leja and MicroCell were very close, respectively 20.0 μm and 20.3 μm, whereas the CellVision was lower than specification (17.9 μm). The accura...
متن کاملMicrofluidic Device Increases Sperm Concentration by Optimization of Chamber Structure
Intracytoplasmic sperm injection (ICSI) is an extremely timeconsuming and tedious procedure in cases of oligozoospermia, because it is difficult to obtain a sufficient number of motile sperms. To circumvent this difficulty, we previously developed a microfluidic device to increase sperm concentration and reduce time required for ICSI. Here, we improved this device by carefully optimizing its di...
متن کاملMicro-cell chamber and washed human spermatozoa.
With the development of the Makler counting chamber, the reproducibility and accuracy of computer-assisted semen analysis and of manual determination of sperm concentration and sperm motility were significantly enhanced beyond what is possible with other methods, such as the hemocytometer, the Horwell chamber, the Petroff-Hausser chamber, and Chartpak slides. The use of Micro-Cell, a disposable...
متن کاملMeasurement of Sperm Concentration in Stallion Ejaculates Using Photometric or Direct Sperm Enumeration Techniques
A highly significant correlation was detected among photometric and direct sperm enumeration techniques for evaluating sperm concentration. Depending on the instrument used, the photometric techniques tended to overestimate or underestimate sperm concentration when compared to a hemacytometer standard. Precautions should be taken when using techniques other than a hemacytometer to measure sperm...
متن کاملAccuracy Evaluation of The Depth of Six Kinds of Sperm Counting Chambers for both Manual and Computer-Aided Semen Analyses
Background Although the depth of the counting chamber is an important factor influencing sperm counting, no research has yet been reported on the measurement and comparison of the depth of the chamber. We measured the exact depths of six kinds of sperm counting chambers and evaluated their accuracy. MaterialsAndMethods In this prospective study, the depths of six kinds of sperm counting chamber...
