Sperm washing ($100.00)
Sperm are washed with tissue culture medium to remove the seminal plasma. The cells are centrifuged and resuspended in less than a milliliter of medium to concentrate the sperm in a small volume.
Swim-up ($110.00)
This procedure selects the most morphologically normal and most motile sperm from the semen sample. Washed semen is overlaid with tissue culture medium and incubated approximately 1-2 hours. From the upper regions of the medium the sperm are harvested, centrifuged, and resuspended in concentrated form. The resulting preparation contains sperm with improved motility and morphology and is devoid of round cells and debris.
Isolate gradient separation ($110.00)
This is a method of sperm selection in which sperm are separated by centrifugation on the discontinuous Isolate gradient. This method concentrates viable sperm into a small volume, isolates sperm of higher motility, and increases the fertilization capability of the spermatozoa. It is especially useful in cases of asthenozoospermia and oligozoospermia, where the swim-up procedure is a less successful means of isolation.
