Sperm Preparation
Laboratory processing techniques to isolate motile, morphologically normal sperm for use in assisted reproduction procedures.
Full Definition
Sperm preparation encompasses various laboratory techniques designed to separate viable, motile sperm from seminal plasma and debris for use in ART procedures. Common methods include density gradient centrifugation, swim-up technique, and sperm washing procedures. These techniques concentrate motile sperm while removing dead sperm, white blood cells, bacteria, and seminal fluid components that may impair fertilization. The choice of preparation method depends on semen parameters, intended use (IUI versus IVF/ICSI), and laboratory protocols. Quality control measures ensure optimal sperm recovery and functionality. Prepared sperm samples are assessed for concentration, motility, and morphology before use in reproductive procedures.
Usage
Usage note: Hyphenate when used as compound adjective; use as two words for the process itself.
