3. Figure 2
Bioanalyzer read-out of CMV DNA PCR. The PCR products loaded into a DNA 1000 “lab-on-a-chip” (Agilent Bioanalyzer) for microelectrophoresis are separated according to size, and the resulting electropherogram is rendered as a gel image for easy interpretation of products. Lane L is the base pair ladder; lanes 1–6 are β-globin internal control PCR products (172 bp) of semen specimens assigned laboratory log numbers 12162, 12192, and 12121, plus a new positive control preparation, the old positive control, and a PCR blank. Lanes 7–12 are CMV PCR products (220 bp) from the same semen specimens and controls. Cytomegalovirus DNA was detectable in log numbers and but not 12162.

4. Figure 3
Frequency of CMV-positive semen specimens relative to CD4+ lymphocytes per microliter of blood. The ratios of CMV-positive semen specimens to total specimens from the cohort of men submitting three semen specimens for analysis were grouped according to CD4+ lymphocyte counts in bins of 100–300, 301–500, 501–700, 701–900, 901–1,100, 1,101–1,300, and 1,301–1,500. Numbers in the bars are CMV+ specimens per total specimens in that group. Using Fisher's two-tailed exact test, semen specimens were statistically significantly more likely to test positive for CMV if the man's peripheral blood CD4+ cell count was <700/μL blood (P=.0005).
