Previously reported age predictors were tested using 450K array data for 36 body fluid samples.
Age-related CpG candidates were selected from the array results of 12 semen samples.
Age-predictability of selected CpGs was tested in 68 semen samples.
Age-predictive model generated with 3 CpGs showed prediction error of approximately 5 years.
The CpG sites in the TTC7B gene and the NOX4 gene showed high age prediction capability.
