Description of CpGs in terms of number and methylation status in the swim-up sperm fraction and in B cells.

The number of hypomethylated and hypermethylated loci are indicated as total, autosomic, X chromosome and Y chromosome-linked. A) Sperm CpG numbers refer singularly to the eight normozoospermic men, while B cells CpG numbers belong to two different subjects. The mean CpG number ± DS and the percentage calculated in respect to the mean total CpG number for each group are reported in the middle panel; B) Number of CpGs conserved among individuals: the first raw reports the number of CpGs shared by individuals, while the second raw reports the percentage of conserved CpGs compared to the mean CpG number reported in panel A.

低甲基化位点与高甲基化位点的数量分别按总位点、常染色体位点、X染色体位点及Y染色体连锁位点进行标注。A) 精子样本的CpG（胞嘧啶-磷酸-鸟嘌呤二核苷酸）数量仅针对8名正常精子症男性；B细胞样本的CpG数量则来源于2名不同受试者。中间面板展示了各组CpG数量的平均值±DS，以及各组相对于总平均CpG数量计算得到的百分比。B) 个体间保守CpG位点的数量统计：第一行列出了所有受试个体共有的CpG位点数量，第二行则列出了相较于A面板中报告的平均CpG数量，保守CpG位点所占的百分比。
