The epigenome is highly responsive to various metabolic, cellular, and physiological signals [25, 26], and the immediate pre-pubertal period is clearly a particularly sensitive period for moderating SRD5A1 expression given that it is normally upregulated at this time, as seen also in other developmental genome-wide screens [86]
