  Abbreviations: CL, confidence limit; k, number of samples from a future subject; TSperm, total number of sperm per ejaculate.
  aEstimated by method 1, assuming that the new observed value for TSperm/h is 1.00. Multiplying the average observed TSperm/h abstinence for future samples by the appropriate pair of factors will provide CLs for that individual. These values are compared with those calculated by other methods in Supplemental Table 1.
