Treatment protocol Sperm from semen was extracted using gradient method and purified DNA was isolated our previously developed method of beads, RLT and TCEPS
Extracted molecule genomic DNA
Extraction protocol Standard Illumina Protocol
Label Cy3,Cy5
Label protocol Standard Illumina Protocol
 
Hybridization protocol bisulphite converted DNA was amplified, fragmented and hybridised to Illumina Infinium HumanMethylationEPIC BeadChip using standard Illumina protocol
Scan protocol Arrays were imaged using BeadArray Reader using standard recommended Illumina scanner setting
Description sperm DNA methylation
Processed_methylation_data_matrix_LIFE.RData
Data processing Sperm DNA methylation was assessed using Illumina's EPIC Infinium Methylation Beadchip. Raw idat files were imported into R and within-array normalization and dye-bias equalization of Type I and Type II probes was performed using normal-exponential convolution method (Noob) via minfi package. Batch effects were corrected with the ComBat function in the sva package while cross-hybridizing probes were removed using the DMRcate package. probes with detection pvalue >0.01 were also exluced prior to downstream analysis.
Processed matrix contains the NOOB-normalized beta values representing the percent CpG methylation for all the CpGs that passed the preprocessing method.
