Description: Sperm concentration, motility, and morphology were assessed in 765 men in infertile couples and 696 men in fertile couples to identify values that would distinguish fertile from subfertile men. Subfertile ranges were a sperm concentration of less than 13.5 million per milliliter, less than 32 percent motility, and less than 9 percent sperm with normal morphologic features. Fertile ranges were a concentration greater than 48.0 million per milliliter, greater than 63 percent motility, and greater than 12 percent normal morphologic features. However, there was extensive overlap between fertile and infertile men with regard to all measures. Semen analysis is routinely used to evaluate the male partner in infertile couples 1 , 2 and to assess the reproductive toxicity of environmental or therapeutic agents. 3 Although widely used thresholds for normal semen measurements have been published by the World Health Organization (WHO), 4 – 7 the available norms for sperm concentration, motility, and morphology fail to meet rigorous clinical, technical, and statistical standards. In recognition of these limitations, the nomenclature in the most recent WHO manual 7 for semen evaluation was changed from “normal” to “reference” values. Two recent prospective studies of semen quality and fertility concluded that the current WHO reference values . . .
