Figure 2 Comparison of HIV-1 RNA in the motile sperm fractions from single tube gradient (n = 3), swim-up (n = 3), and double tube gradient (n = 3) methods using ISolate sperm separation medium. Data are represented as mean ± standard error HIV-1 RNA copy number per motile sperm fraction. Politch. Removal of HIV-1 from motile sperm fraction.Fertil Steril 2004.

Figure 3 Comparison of HIV-1 RNA in the motile sperm fractions from single tube gradient (n = 6), gradient/swim-up (n = 6), and double tube gradient (n = 6) methods using ISolate sperm separation medium.

Figure 4 Comparison of sperm yield in the motile sperm fractions from single tube gradient , double tube gradient , and gradient/swim-up methods using ISolate and Percoll sperm separation media. Data are represented as mean ± standard error percent total motile sperm of initial sample. No statistically significant differences in sperm yield were found between ISolate and Percoll. Politch.
