Accu-Beads as a quality control measure for manual and automated methods of measuring sperm concentration-an observational study.

Purpose: To determine the precision and accuracy of Accu-Beads and their utility as a quality control product for manual and automated measurements of sperm concentration.

Methods: This observational study was performed at an Assisted Reproductive Technology laboratory in a tertiary-care, university hospital. To simulate sperm concentration, bead concentrations were measured with the use of a manual and an automated method.
