Abstract:
OBJECTIVE:To propose the sperm recovering efficiency (SRE) model, an equation that can be used to objectively quantify the technical skill of individual operators processing semen specimens in an andrology laboratory. Additionally, this equation can be used to compare different semen processing methods and protocols. This model integrates the semen parameters of initial sperm concentration, motility, morphology, and final sperm recovery to produce a unique number that can be used to compare results. DESIGN:A theoretical and deductive analysis. SETTINGS:Private assisted reproductive units. PATIENT(S):None. INTERVENTION(S):None. MAIN OUTCOME MEASURE(S):Motile progressive and morphologically normal sperm concentration. RESULT(S):The SRE is a mathematical equation that can be used to compare initial semen parameters to postpreparation concentration, progressive motility, and normal morphology. The result is a number between 0 and 1. The model constitutes an objective means for determining the efficiency of a particular technique (gradients, migration, or filtration) or to set up the best conditions for that technique (time, gravities, medium volume, and sample volume). Additionally, the SRE permits comparisons between different operators, media, lots, laboratory conditions, treatments, and sample parameters. It can be used as a tool in laboratory quality control and for multicenter studies. CONCLUSION(S):Sperm recovering efficiency (SRE) is an objective method to compare the results of semen processing techniques.
