Intracytoplasmic Morphology-Selected Sperm Injection
2012Approximately 40% of sterility in couples can be attributed to male subfertility and intracytoplasmic sperm injection (ICSI) has become a powerful tool in assisted reproduction to overcome male infertility. Intracytoplasmic morphologically selected sperm injection (IMSI) is an advanced and sophisticated method of ICSI, where prior to sperm injection ...

Sperm Selection by Colloid Centrifugation
Colloid centrifugation has several uses within spermatology. It has traditionally been used as a biomimetic method to select the most robust, fertile spermatozoa from a sperm sample. However, any sub-population can be selected, or the spermatozoa can be separated from seminal plasma, by changing the density of the colloid used.openaire +2 more sources
XY Sperm Separation for Sex Selection
Urologic Clinics of North America, 1987At present, laboratory methods that can successfully differentiate X- from Y-bearing sperm do exist; namely, staining with quinacrine mustard and DNA flow cytometry. However, methods that can successfully and reproducibly separate X- from Y-bearing sperm with resultant functionally intact sperm have yet to be developed.

Sperm Selection Based on Electrostatic Charge
2012Charge is a fundamental property of all forms of matter that exhibit attraction or repulsion in the presence of another charged particle. This electrokinetic property occurs when the particles exhibiting a net negative or positive charge are subjected to an external electric field that exerts an electrostatic force between them. Sperm surface membranes

[Sperm quality and selection].
Journal de gynecologie, obstetrique et biologie de la reproduction, 2008Selection of a live and morphologically normal spermatozoa is a fundamental stage in ICSI success because of its potential effects on early and late embryo development. In addition to the routine tests such as the spermogram and the spermocytogram, a number of tests have been developed for this purpose : the hyaluronic acid test, which measures the ...
