• Time Savings: Sample processing with both the SpermPrep I & II are typically completed within 25 minutes.
• Safe & Convenient: The SpermPrep Columns are Gamma Ray sterilized, individually packaged and disposable.
• Simple: The columns are easy to use and require minimum handling.
• Selective: SpermPrep selects DNA-healthy fertile spermatozoa during filtration.
• Economical: Priced to reduce the cost to your patients.

SpermPrep I - $13.00

Oligospermic and post thaw specimens: SpermPrep I disposable semen filtration columns have been shown to dramatically improve the recovery of motile sperm in processed oligospermic and post-thaw specimens in comparison to the conventional swim-up technique.  Twenty specimens prepared by both the SpermPrep I and swim-up methods were assessed for motility, grade, morphology, intact acrosomes,debris present, and concentration recovered. 

The samples showed no significant differences in any of the qualitative measurements; however, the number of sperm recovered by the SpermPrep I method was 58% of the original concentration vs 7% by swim-up.  A further comparison of total functional sperm fraction (total sperm recovered [x10⁶] x percent motility x percent normal spermatozoa/[1.0x10⁶]) showed a 341% improvement in yield by SpermPrep I vs swim-up¹. 

This improvement is of particular significance in the preparation of oligospermic and post-thaw samples for critically timed IVF and GIFT procedures, as well as,  in samples prepared for AI and IUI in female patients who have undergone hormonal stimulation.

SpermPrep II - $16.00

Normospermic, asthenospermic and teratospermic samples: SpermPrep II disposable semen filtration columns combine the same filtration technology proven in the original SpermPrep I columns with greater convenience and speed.  SpermPrep II is designed for use with normospermic specimens and those which have a normal count but which may be deficient in other qualitative parameters.

This rapid method effectively removes dead cells and other spermatozoa with DNA abnormalities potentially antigenic debris from the sample to provide the highest quality specimen for todayís assisted reproductive techniques.
